Cryptocurrency is accessible anywhere. It feels smart and sophisticated. It is built to be technologically secure. It can be an asset as well as, in some parts of the world, a means of payment. It can be converted into fiat (cash) at a moment’s notice. And, unlike conventional financial instruments, it offers no barriers to adoption. With as little as a hundred rupees, an aspiring youngster in the hinterlands of India can buy a fraction of cryptocurrency and feel like a grand investor.
Mitali Mukherjee’s book Crypto Crimes deals with this alluring asset class that has the potential to exist beyond the reaches of governments and conventional financial institutions or at least dodge easy scrutiny by governments. This is why crypto is so popular among scamsters, kidnappers, extortionists, drug peddlers, hawala operators, terrorism financiers, and ransomware invaders. Mukherjee successfully depicts this web of nefarious activities. She describes the world of crypto as one without guardrails, lethal to many, and potentially dangerous to all. Like a good journalist, she does this by expertly piling fact-filled passages upon each other.
Crypto Crimes: Inside India’s Best-Kept Secret
By Mitali Mukherjee
HarperCollins India
Pages: 336
Price: Rs.499
Two chapters dedicated to the threat posed by ransomware attacks offer us details about how a cross section of Indian organisations—both public and private—were affected. The list includes JNPT, SpiceJet, Oil India Limited, Dr Reddy’s, BSNL, Mobikwik, Paytm Mall, BigBasket, and AIIMS. In this model, the invaders have the option to not only extract ransom but also earn through the sale of sensitive personal information of the customers of these companies. The author highlights the inadequacies of security frameworks in many Indian corporates and also how some companies under attack resort to denials or react irrationally against whistle-blowers or those offering a helping hand.
Even more revealing is the existence of “Ransomware-as-a-Service” groups that lease technologies to other groups that actually carry out the attack. But what is crypto’s role in ransomware? Well, it brings scalability to this grimly innovative industry by offering convenience and anonymity and, therefore, the promise of an untraceable escape.

Need for regulations
The book helps one understand the dire need for standardised regulations, protocols, and practices for this porous currency, which has as much disregard for national borders as greenhouse gases. However, with world leaders unable to build a consensus to combat greater existential threats such as climate change and AI, the only hope is that the global crypto market offers sufficient financial incentive for such a consensus to be reached.
As things stand, three different entities of the Indian government itself—the RBI, the Securities and Exchange Board of India, and the Ministry of Finance—are unable to agree upon the approach to cryptocurrency. Whereas the RBI has been sounding the warning bugle since 2013, the ministry has been inconsistent in its response. It has pondered over banning cryptocurrency altogether, created committees at various points that made different recommendations, and mulled over the introduction of its own virtual currency (Central Bank Digital Currency) and, after all these years, still has not formulated regulations for the domain. However, in 2022, it did announce heavy taxation of gains made in cryptocurrency, which affected the industry. Without a trace of irony, the Finance Minister denied that this move offered legitimacy to crypto and instead claimed “a sovereign right to tax”.
The book captures a sole, sane voice from within the corridors of power: former Finance Secretary Subhash Chandra Garg, who recommends that policy-making precede legislation, which can then lead to well-framed and implementable regulations.
The book makes a compelling case for regulating cryptocurrency that may be longer-lasting than its detractors believe
Two chapters on ransomware attacks offer us details about how a cross section of Indian organisations were affected by these.
However the book suffers from poor storytelling and repetitiveness.
Tedious and repetitive
Now for the flaws of the book. The author often overloads the reader with information while resorting to poor storytelling, except in the last few chapters, which are more free-flowing. In some chapters, the same point is repeated in a loop, with a new source offering a similar or slightly differing perspective of the same point. In the process, the drama, emotions, and imagery surrounding poignant human moments are left untapped. Can a serious book not also be evocative?
Had the organisation of information been better, this would have been a much smaller book. It does not help that key points are repeated ad nauseum. These include the specific vulnerabilities of India to crypto crimes, the speed with which the technology penetrated rural and semi-rural landscapes in the country, market fluctuations vis-a-vis the pandemic, and the involvement of Russian and Chinese entities in ransomware attacks and extortions respectively. Sometimes, the same study is cited twice in a span of a few pages, such as the mention of Maharashtra being the target of 42 per cent of ransomware attacks in India. One wonders whether each chapter was written like an isolated article and, therefore, the author felt compelled to set contexts and data points all over again.
For a book that relies extensively on surveys and statistics, it seems astonishing that the author has made no attempt to leverage infographics. These could have made the points more memorable, while offering the beginnings of analysis. Forget a grand diorama of stakeholders, issues, and interactions, the book does not include even a timeline of events or a simple table or graph that would help one absorb comparative data.

Although the book has the viscous storytelling of a scholarly study, it lacks the rigour to make it one. A great deal of the book relies on secondary research; while citing these external sources of information, the author hardly ever offers more than rudimentary analysis of her own. And the primary research itself is unsatisfactory. The author has interviewed technocrats, the odd retail investor, some insiders, and a few crypto entrepreneurs. She walks on eggshells with the latter category, making no attempt to provoke or even challenge their self-serving opinions. For instance, when BuyUCoin co-founder Shivam Thakral laments the lack of financial literacy among Indians, the author does not ask whether this puts a greater onus on the government to protect such a target audience from harm. Perhaps just making an observation in this regard would have sufficed. Similarly, while interviewing Nischal Shetty, the co-founder of WazirX—a company that was slapped with a show-cause notice for allegedly contravening regulations of the Foreign Exchange Management Act to the tune of Rs.2,790.74 crore—who refuses to look within and states that people will always choose freedom (as opposed to regulations), she does not ask if all people, including the honest retail investor, would object to regulations that protect them. Finally, in a book based on hard research, the citations provided are not substantiated either in the back pages of the book or in the publisher’s website URL linked to a QR code that promises “Detailed Notes” on both the front and back sides of the book.
Overall, Mukherjee makes a compelling case for regulating this new asset class that may be longer-lasting than its detractors believe while also highlighting its potential for positive transformation. This makes the book a ready reckoner for those who want to delve into and dwell on the world of crypto. Others are likely to find it tedious and mediocre.

APOPKA, Fla. – A 34-year-old Florida man, who served as the president and CEO of an alleged cryptocurrency investment firm, has been accused of running a $328 million Ponzi scheme, according to the U.S. Department of Justice.
Christopher Alexander Delgado, of Apopka, Florida, was arrested on federal charges of wire fraud and money laundering, the DOJ announced on Tuesday.
The backstory:

According to the DOJ, Delgado was the CEO and founder of Goliath Ventures, formerly known as Gen-Z Venture Firm.
The DOJ alleges that Delgado convinced people to invest a total of $328 million with his firm between January 2023 & January 2026 under the assumption that it would be invested in cryptocurrency “liquidity pools” – and would promise monthly returns.
Advertisement
The DOJ alleges that the money was instead used to pay returns and principals to previous investors, as well as to pay for lavish business gatherings, holiday parties, and to buy four multi-million-dollar homes (varying in cost between 1.15M and $8.5M).
“Victims were induced to give money to Goliath through personal referrals, professional marketing materials, luxury events, charitable sponsorships, and some monthly payments of purported returns, all of which were designed to establish Goliath’s bona fides with investors,” the DOJ said in a news release.
If convicted, Delgado faces up to 30 years in federal prison, the DOJ said.

According to the complaint, Delgado bought four homes:
$3.2 million home in Winter Park in July 2025
$1.15 million home in Kissimee in December 2024
$8.5 million home in Windermere in September 2025
$1.65 million home in Sanford in August 2024
Victim: Lost $720,000
According to the complaint, one unnamed investor reportedly lost $720,000 in Delgado’s alleged scheme. A second investor was reportedly able to get his money back, though he had to directly contact Delgado to ensure he did. The amount of money returned in the second example was not disclosed.

In 2026, every serious crypto product relies on a strong API. APIs power trading bots, wallets, payment apps, and analytics dashboards. This guide reviews 15+ leading cryptocurrency APIs across market data, exchanges, blockchain nodes, and payments. By the end, you will learn how to evaluate them and understand key trends such as WebSocket streaming, DEX integrations, and NFT APIs. Let’s break it down clearly and practically.
What Are Cryptocurrency APIs?
A crypto API is a software interface that allows one application to communicate with another system, such as a blockchain network or a crypto exchange. It acts as a bridge. Your app sends a request and the API connects to the blockchain or exchange. Then it returns structured data in seconds.
Developers use APIs to fetch prices, check balances, place trades, or broadcast transactions. Without APIs, teams would need to run full nodes and build complex infrastructure.
Most APIs use REST for standard requests like price queries. WebSocket APIs stream real-time data, such as live trades or order books. As a result, APIs reduce complexity and accelerate crypto adoption worldwide.
Types of Crypto Data APIs
Every crypto data API serves a specific function. Some provide market prices. Others enable trading or blockchain access. Some help merchants accept payments. In practice, most crypto products combine several API types. The four core categories are market data APIs, exchange APIs, blockchain APIs, and payment processing APIs. Each plays a different role in the ecosystem.
Market Data APIs
A cryptocurrency market data API delivers price information, trading volume, and market capitalization. Developers use it to build portfolio trackers, price comparison tools, and analytics dashboards. These APIs offer real-time data for live updates and historical data for analysis. Many also provide OHLCV data for charting. Most market data APIs are read-only. Therefore, they usually do not require user authentication.

Exchange APIs
A crypto exchange API enables trading operations on centralized exchanges. It offers public endpoints for price data and private endpoints for account actions. Developers must use API keys and HMAC signatures for authentication. These APIs allow users to place orders, check balances, and review trade history. Because trading involves funds, exchanges require KYC compliance for verified accounts.
Blockchain APIs
A blockchain API gives developers direct access to blockchain networks without running full nodes. It allows applications to query balances, track transactions, and broadcast new transfers. Many also support smart contract interaction. Popular networks include Ethereum, Bitcoin, and Solana. Developers use these APIs to build wallets, DApps, NFT platforms, and blockchain explorers efficiently.
Payment Processing APIs
A cryptocurrency payment gateway API helps merchants accept digital asset payments. It detects incoming transactions and confirms them automatically. Many providers convert crypto to fiat at settlement. These APIs support invoice creation and multi-currency payments. They also handle compliance, risk checks, and pricing models. As a result, businesses can integrate crypto payments quickly and securely.
Key Features to Evaluate
Choosing the right API depends on your use case. A trading bot needs speed. A portfolio app needs reliable data. Therefore, you must compare key factors before integration. Focus on accuracy, performance, coverage, documentation quality, security standards, and pricing structure. These elements define long-term stability and scalability.
Data Accuracy and Coverage
Accuracy is critical in crypto because prices change every second. A weak cryptocurrency price data API can show outdated or incorrect values. Always check data freshness and update frequency. Review how the provider aggregates data and whether sources remain transparent. Reliable APIs publish uptime SLAs and maintain stable infrastructure. Also compare how many cryptocurrencies and exchanges they support. Broad coverage improves flexibility and reduces dependency on multiple providers.

Performance and Documentation
Low latency matters for trading and real-time dashboards. Test response times under load before full deployment. Rate limits also affect performance, especially for high-frequency requests. Clear crypto API documentation reduces integration errors. Strong providers offer SDKs, code examples, API explorers, and step-by-step guides. Good documentation saves development time and lowers maintenance costs.
Best Cryptocurrency Market Data APIs
Most developers start with a price feed. The best crypto data API delivers reliable market data at scale. These APIs power tracking apps, trading dashboards, and analytics tools. Many providers offer free tiers, but limits vary. Below are three leading options in 2026
CoinGecko API
The CoinGecko API ranks among the most widely used market data APIs in the industry. It covers over 10,000 cryptocurrencies and tracks more than 600 exchanges worldwide. Developers can access prices, trading volumes, market caps, DeFi metrics, and NFT floor prices through structured REST endpoints.
The free tier allows up to 50 calls per minute, which works well for small apps and prototypes. In 2026, paid plans include Analyst at $129 per month, Lite at $499 per month, and Pro at $999 per month. Higher tiers unlock greater rate limits and advanced endpoints.
The main advantage is its generous free tier and broad asset coverage. Integration remains simple thanks to clear documentation. However, rate limits can restrict high-frequency use. Some users also report occasional short delays during peak volatility. Overall, CoinGecko remains a strong choice for both beginners and scaling projects.

CoinMarketCap API
The CoinMarketCap API carries strong institutional credibility. Many enterprises rely on it for structured and consistent market data. It tracks more than 9,000 cryptocurrencies and offers historical data going back to 2013. This long-term dataset supports deep research and backtesting.
The platform uses a credit-based system. The Basic plan remains free but offers limited access. Paid tiers range from Hobbyist at around $29 per month to higher Enterprise plans with custom pricing. Costs increase as request volume grows.
The key strength lies in reliability and historical depth. Large funds and fintech apps often prefer it for compliance and reporting. However, the free tier remains restrictive. High-volume usage can also become expensive quickly. For professional environments, it remains a trusted option
Messari API
The Messari API focuses on professional research and curated crypto intelligence. It combines market data with fundamental analysis and on-chain metrics. Developers can access structured datasets, DeFi statistics, and advanced indicators. One standout feature is the Real 10 Volume metric, which filters unreliable exchange activity.
In 2026, the Professional plan costs around $25 per month, while Enterprise pricing remains custom. Compared to other providers, coverage includes fewer assets but higher-quality research.

The main advantage is curated and transparent data. Analysts and research platforms benefit most from this API. The main drawback is narrower asset coverage and pricing that may exceed basic project budgets.
Best Cryptocurrency Exchange APIs
The best cryptocurrency exchange api allows developers to access trading functions and real-time market data directly from exchanges. These APIs require account creation and, in most cases, KYC verification. Because they handle funds, security becomes critical. Below are leading centralized and instant exchange solutions in 2026.
Binance API
The Binance API powers the world’s largest exchange by trading volume. It supports Spot, Futures, and Margin trading through structured REST and WebSocket endpoints. Developers use it as a full cryptocurrency trading API for order execution, balance tracking, and historical trade analysis.
Binance applies a weight-based rate limit system, capped at 1200 weight per minute. This model allows flexibility but requires monitoring request usage carefully. The API provides live market data, order book depth, account management, and real-time WebSocket streams.
Security relies on API keys and HMAC SHA256 signatures. Developers must sign private requests properly. Binance also offers a Testnet environment for safe testing before deploying to production.
Advertisement
The main advantage is deep liquidity and global coverage. Documentation remains detailed and actively maintained. However, regulatory restrictions apply in some regions. The API structure can also feel complex for beginners due to many endpoints and trading rules.
Coinbase API
The Coinbase API focuses on compliance and user trust. It offers Consumer, Exchange, and Commerce APIs. Developers can integrate buy and sell functions, wallets, merchant tools, and professional trading features. The Advanced Trade API serves active traders.
Authentication uses OAuth2 and API keys. Fiat integration remains a major strength. Developers can link bank transfers and card payments directly within applications.
The platform holds strong U.S. regulatory compliance, which benefits fintech startups targeting American users. Security standards remain high, and infrastructure stability is strong.
However, trading fees tend to be higher than competitors. Asset coverage also remains smaller compared to Binance. For regulated markets and fiat-heavy platforms, Coinbase remains a reliable cryptocurrency exchange api option.

StealthEX API
The StealthEX API provides an instant crypto exchange API built on a non-custodial model. It supports over 2,000 cryptocurrencies and more than 100 fiat currencies. Users do not need registration to swap assets. This structure makes it a strong non-custodial API for wallet and aggregator integrations.
The API uses RESTful endpoints and supports both fixed-rate and floating-rate swaps. Partners can set a customizable commission between 0 and 0.5 percent, with revenue-sharing options available. The average swap completes in under 15 minutes.
White-label solutions allow companies to integrate exchange functionality directly into their platforms. The model works well for wallets, fiat providers, and comparison services.
Advantages include no mandatory user KYC, broad asset coverage, and flexible pricing. However, this API does not support advanced order types or high-frequency trading strategies. It focuses on instant crypto swaps rather than order book trading.
Best Blockchain and Node APIs
A strong Bitcoin API or multi-chain node API allows developers to interact with blockchain networks without running full nodes. This saves infrastructure costs and setup time. Node access APIs provide raw JSON-RPC endpoints. Enhanced platforms add indexing, analytics, and developer tools on top. Multi-chain support is now essential for modern DApps.

Infura
Infura remains one of the most established infrastructure providers in Web3. ConsenSys owns and operates the platform. It started as Ethereum-focused infrastructure and later expanded to support Polygon, Optimism, Arbitrum, and other networks.
Infura provides standard JSON-RPC endpoints and WebSocket connections. Developers use it to read blockchain data, send transactions, and interact with smart contracts. It also supports IPFS for decentralized storage use cases.
The free tier allows up to 100,000 requests per day. Paid plans start around $50 per month in 2026, with higher tiers based on request volume. The platform offers a 99.9% uptime SLA, which matters for production-grade applications.
Infura works well for wallet apps, NFT platforms, and DApps that require stable Ethereum infrastructure. It also plays a role in cryptocurrency exchange integration, where platforms need reliable node connectivity for deposit monitoring.
The main advantage is industry-standard reliability and wide ecosystem adoption. However, costs can rise quickly at scale, especially for high-traffic applications.

Cryptocurrency Payment APIs
A strong cryptocurrency payment API allows merchants to accept digital assets without deep technical knowledge. These APIs simplify e-commerce integration and improve user experience. They offer payment buttons, invoice generation, and shopping cart plugins. Many also convert crypto into fiat automatically, which reduces volatility risk for businesses.
NOWPayments
NOWPayments provides a simple and flexible free cryptocurrency API model with transparent pricing. It supports over 150 cryptocurrencies, including major assets and stablecoins. Developers can integrate the API directly or use ready-made plugins for WooCommerce and Shopify.
The platform offers automatic coin conversion and mass payout functionality. Merchants can accept one asset and settle in another. The pricing model remains straightforward, with a 0.5% processing fee.
Setup takes minutes, and documentation remains clear for beginners. The main advantage is ease of integration and broad asset support. However, fees remain higher than self-hosted solutions. Businesses also depend on a third-party provider for transaction processing and compliance.
Specialized APIs: DeFi and NFT
A DeFi API targets specific blockchain sectors like decentralized finance and NFTs. These APIs provide deeper protocol-level data than general market APIs. Developers often combine them with broader infrastructure tools to build advanced dashboards and trading applications.
Advertisement
DeFi and DEX APIs
A DEX API connects applications to decentralized exchanges and DeFi protocols. Developers access liquidity data, swap routes, and protocol metrics without relying on centralized exchanges.
Uniswap data is often accessed through The Graph subgraphs, which index blockchain events. The 1inch API aggregates liquidity across multiple DEX platforms and calculates the best trading route automatically. DeFiLlama provides total value locked (TVL) data and protocol rankings, and it remains free for public use.
These APIs power DeFi dashboards, yield aggregators, and portfolio analytics tools. The main advantage is decentralized liquidity and no KYC requirements. However, smart contract risk and integration complexity require careful testing and security audits.
How to Choose the Right API
There is no single best cryptocurrency API for every project. The right choice depends on your goals. Start by defining your exact use case and required metrics. Compare providers based on features, performance, and pricing. Test integration in a staging environment. Monitor uptime and latency continuously. Many professional projects combine multiple APIs to reduce risk and improve coverage.
Technical and Budget Considerations
Every crypto API for developers must match both technical and financial constraints. First, define your data needs. Do you need real-time streaming or daily updates? Estimate expected request volume and traffic growth. Review performance requirements such as latency and rate limits.
Advertisement
Next, analyze pricing models. Some providers charge per request. Others use credit systems or compute units. Support level and SLA guarantees also affect cost. Map each use case to API capabilities. Finally, calculate projected monthly expenses based on expected call volume before committing to a paid tier.
