The development of blockchain has moved well beyond the proof of concept stage. In 2026, developers and traders regularly work across multiple chains, extract portfolio data from dozens of networks, and feed bots, dashboards, and AI agents with real-time market information. What all of these workflows have in common is a reliable crypto API.

In Brief
- Crypto APIs allow developers and traders to access multi-chain data, market prices, and wallet activity without managing their own infrastructure.
- Major providers like CoinStats, Alchemy, Moralis, Helius, and Bitquery each specialize in different tiers, from RPC access to rich analytics.
- Choosing the right API depends on channel coverage, data depth, pricing model, and the complexity of your application.
Crypto APIs (Application Programming Interfaces) allow software to interact with blockchain networks and market data sources programmatically. Rather than operating your own nodes, indexing raw on-chain data, or manually aggregating prices, a good API abstracts this complexity into clear endpoints that you can call with a few lines of code. The result: faster development cycles, reduced infrastructure costs, and more of time spent building the product itself.
Choosing the right API, however, depends on what you’re building. Some providers focus on low-level RPC access and node infrastructure. Others specialize in aggregated market data, portfolio tracking, or DeFi analytics. A few attempt to unify all of this under a single integration. The five providers below represent an overview of crypto APIs in 2026, each with a distinct approach to multi-chain data.
What to Look for in a Crypto API
Before evaluating specific providers, it’s helpful to define the criteria that matter most when choosing a crypto data API.
- Channel coverage determines how many networks you can support through a single integration. If your product tracks wallets or multi-chain wallets on EVM, Solana and Bitcoin, an API covering all three under a single schema saves significant development time compared to assembling specific providers per chain.
- Data depth refers to the degree of processing the API does for you. Raw RPC data requires parsing, enrichment and normalization before being usable in an interface. Higher-level APIs return balances with USD valuations, decoded transaction histories, and DeFi position breakdowns right out of the box.
- Pricing model varies greatly between suppliers. Some charge per request, others use calculation units adjusted to the complexity of the requests, and some offer fixed monthly plans. Understanding this pattern is crucial, especially as usage grows.
- Documentation and developer experience influence how quickly a team moves from registration to functional integration. Well-organized docs, code samples in multiple languages, and responsive support channels reduce friction during development.
With these criteria in mind, here are five crypto API providers to consider in 2026.
1. API CoinStats
Focus : Unified multi-chain data for wallets, marketplaces, DeFi and wallets
The CoinStats API takes a broad approach to crypto data by combining portfolio tracking, market insights, DeFi position detection, and portfolio analytics in a single integration. It covers more than 120 blockchains and aggregates data from more than 200 exchanges and 10,000 DeFi protocols.
Données de portefeuilles are among the strengths of the API. Developers can query balances and transaction histories for Solana, Ethereum and EVM-compatible chains (Polygon, Arbitrum, Optimism, Avalanche, Base, BSC, etc.), as well as Bitcoin (including xpub/ypub/zpub extended public keys) via a consistent endpoint structure. A single call to the Multi-Chain Balances endpoint can return token holdings across all supported EVM networks simultaneously, avoiding the need to query each chain individually.
On the market data side, the API provides real-time prices, market caps, volumes and historical charts for thousands of cryptocurrencies. The coverage threshold is approximately $50,000 in liquidity and trading volume, meaning that most actively traded tokens are included regardless of the chain or exchange where they are traded.
DeFi positions are automatically detected on over 1,000 protocols. Staking positions, loans, liquidity providers (LPs), and yield data appear alongside standard wallet balances without requiring separate integrations per protocol.
For teams developing AI-powered tools, CoinStats offers Model Context Protocol (MCP) support, which exposes API capabilities like callable tools for AI assistants and IDE integrations such as Claude Code and Cursor. This is a relatively new category of API functionality, and CoinStats is among the providers that offer top-notch support.
Wallet endpoints allow developers to access data already stored in a user’s CoinStats account (total value, holding distribution, P/L charts) via a ShareToken authentication mechanism. This is useful for building custom analytics layers, built-in portfolio widgets, or performance dashboards on top of existing CoinStats data.
Pricing: The API uses a credit-based system. A free tier offers 50,000 credits per month at 5 requests per second. Paid plans start at $49/month (1M credits, 30 req/s), with Pro at $199/month (5M credits) and Business at $999/month (80M credits). Enterprise plans are available with custom limits. Authentication is done via an X-API-KEY header.
Consider the CoinStats API if you need wallet, market and DeFi data across multiple chains via a single integration, or if you are building wallet-oriented products benefiting from pre-aggregated multi-chain data.
2. Alchemy
Focus : Blockchain infrastructure and RPC access for EVM and Solana
Alchemy is one of the largest blockchain infrastructure providers, primarily known for its Remote Procedure Call (RPC) endpoints. The platform supports Ethereum, Solana, and a growing list of EVM-compatible networks including Polygon, Arbitrum, Optimism, and Base.
Alchemy’s core product is reliable, low-latency access to blockchain nodes. Developers send standard JSON-RPC requests (or native RPC calls to Solana) and receive raw blockchain data in response. The platform handles node management, load balancing, and background uptime monitoring. For Solana specifically, Alchemy has invested in custom infrastructure providing faster retrieval of archived data and higher throughput than many competing RPC providers.
Beyond raw RPC, Alchemy offers several higher-level products. Its NFT API provides metadata and ownership queries. Webhooks allow developers to subscribe to on-chain events (like address activity or mined transactions) without having to do polling. Smart Wallets enable the creation of integrated wallets with social login for EVM and Solana. The platform also supports gas-free transactions on Solana, which can improve the UX of consumer applications.
The major difference with aggregated data providers is what the RPC responses return. They contain the raw state of the blockchain: unformatted balances, undecoded transactional data, without integrated USD valuations or DeFi position tracking. Teams building portfolio dashboards or user interfaces will need to add their own enrichment layer on top of the raw data.
Pricing: Alchemy uses a Computing Units (CU) model. The free tier includes 30 million CU per month. Usage pricing starts at $0.45 per million CU for the first 300M, then drops to $0.40 per million CU. Enterprise plans with SLA are available. The CU model means that costs vary depending on the complexity of the requests.
Consider Alchemy if You need high-performance, reliable node infrastructure for EVM or Solana development and are comfortable building a data enrichment and normalization layer on top of raw RPC.
3. Moral
Focus : High-level Web3 data APIs for EVM and Solana channels
Moralis provides pre-indexed and enriched blockchain data via REST APIs designed to minimize the number of calls needed to create common Web3 features. The platform supports over 19 EVM and Solana chains, and powers applications used by over 100 million end users, including integrations with wallets like MetaMask and Blockchain.com.
The Wallet API returns token balances, NFT holdings, and transaction histories with decoded metadata, USD valuations, and readable labels already included. This allows developers to display wallet contents in a front-end without writing custom parsing logic. The Token API covers real-time and historical prices on DEXs of all supported EVM chains, updated with each block. The NFT API provides collections metadata, ownership data, floor prices, and market transaction histories.
Moralis also offers event data via its Streams product. Developers can configure real-time webhooks that trigger during specific on-chain events (token transfers, contract interactions, price changes), which is useful for building alert systems, automatic trading triggers, or live dashboards.
Moralis is known to be a good fit for rapid prototyping and reducing time-to-market. The APIs are designed so that common tasks (retrieving a full wallet, listing an owner’s NFTs, extracting token prices) require a single endpoint call rather than multiple RPC requests followed by manual enrichment.
The platform is SOC 2 Type 2 certified, which may be important for teams developing in regulated environments or handling sensitive user data.
Pricing: Moralis uses a calculation unit model. A free plan is available for development and testing. Paid plans are billed annually, with pricing that changes according to CU consumption. The average API request consumes approximately 72 CUs, although this varies by endpoint. Enterprise plans with custom terms are available for high-volume use.
Consider Moralis if You want pre-enriched wallet and token data on EVM and Solana chains with minimal backend processing, particularly for wallet apps, wallet trackers, or NFT platforms.
4. Helius
Focus : Infrastructure native Solana, APIs, and streaming of data in real time
Helius is built exclusively for the Solana ecosystem. Rather than spanning multiple chains, Helius is investing deeply in Solana-specific infrastructure: optimized RPC nodes, improved APIs, gRPC-based data streaming, webhooks, and transaction submission tools.
At the infrastructure level, Helius provides shared, dedicated RPC nodes with global distribution and 99.99% availability. Staked connections are included in paid plans, which improves transaction landing rates during periods of network congestion. The platform processes hundreds of millions of RPC requests daily for clients such as Coinbase, Phantom, Backpack, and Pump.fun.
Above the RPC layer, Helius offers several Solana-specific APIs. The Digital Asset Standard (DAS) API provides fast queries for NFT and fungible tokens, including metadata, ownership, and collectible data. Improved transaction APIs decode Solana instructions and token transfers into readable formats, saving developers from having to manually parse raw transactional data. Priority Charge APIs estimate optimal charges based on real-time network conditions.
LaserStream is Helius’ gRPC streaming product for ultra-low latency access to blocks, transactions, and account updates. It is designed for trading firms, market makers, and any application where latency is critical. Enhanced WebSockets and webhooks-based event listeners provide alternative real-time data options with different latency/complexity trade-offs.
Helius also acts as one of the largest Solana validators and offers a Validator-as-a-Service for institutions. The platform holds SOC 2 certification and has partnered with organizations like Bitwise (for their Solana Staking ETF) and Chainalysis.
Pricing: The plans start with a free tier (1M credits, 10 RPC requests/s). The Developer plan is $49/month with 50 RPC requests/s and chat support. Business is $499/month with enhanced WebSockets and 200 RPC requests/s. Professional is $999/month with LaserStream access, 500 RPC requests/s, and direct Slack/Telegram support. Enterprise plans are available for tailored needs.
Consider Helius if You develop exclusively on Solana and need a deep native infrastructure with low-latency streaming, reliable transaction submission, and Solana-specific APIs.
5. Bitquery
Focus : Analyses blockchain multi-chaînes via GraphQL
Bitquery takes a different approach from the other providers listed. Rather than REST endpoints, it routes all queries through a GraphQL interface, giving developers the flexibility to request exactly the data fields needed in a single call. The platform indexes historical and real-time data on over 40 blockchains, including Ethereum, Solana, BSC, Bitcoin, Polygon, Avalanche, Tron, Cosmos, Cardano, and many others.
The GraphQL schema covers a wide range of on-chain data types: token exchanges, transfers, holder analytics, address balances, smart contract events and calls, NFT exchanges, and DEX activity. For trading applications, Bitquery offers a dedicated Crypto Price API that provides pre-aggregated OHLCV data, moving averages (SMA, EMA, WMA), and cross-chain/cross-DEX price aggregation with per-second granularity.
Real-time data is available via three streaming mechanisms: WebSocket GraphQL subscriptions, Apache Kafka streams, and CoreCast gRPC streams (optimized for Solana). This range of streaming options provides teams with flexibility in consuming live blockchain data according to their infrastructure preferences.
Bitquery also provides a Mempool API that simulates unconfirmed transactions, useful for MEV detection and pre-confirmation analyses. For enterprise data teams, Bitquery integrates with cloud data warehouses (AWS S3, Snowflake, Google BigQuery, Azure, Databricks) and supports SQL access, allowing blockchain data to be incorporated into existing analytical pipelines.
The platform includes a browser-based GraphQL IDE for creating, testing, and saving queries before integrating them into application code. An open-source blockchain explorer is also available.
The trade-off with Bitquery is complexity. GraphQL requires a steeper learning curve than REST, and query costs are harder to predict because they depend on the scope and depth of each call. The pricing model uses a points system where intensive queries consume more points.
Pricing: A free Developer plan includes 1,000 trial points with 10 requests per minute and 2 simultaneous streams. Paid commercial plans are available via custom agreements. Academic discounts are offered to students and researchers.
Consider Bitquery if you need deep and flexible on-chain analytics across multiple blockchains, especially for DEX trading data, holder analytics, or compliance use cases where building custom queries is an advantage.
Choosing the Right API
The above suppliers are not interchangeable. Each occupies a different position in the crypto data landscape, and the choice depends on what you’re building.
- If your project requires Unified data from wallets, markets, and DeFi across multiple chains With minimal integration overhead, the CoinStats API consolidates these categories into a single set of endpoints. It is particularly suitable for portfolio trackers, tax tools, and multi-chain wallet applications.
- If you needlow-level blockchain infrastructure With reliable RPC access for EVM or Solana chains, Alchemy offers the node layer that many production applications rely on. Get ready to build your own enrichment layer on top.
- If you want Pre-enriched Web3 data, ready for display for token portfolios and analyzes without heavy backend processing, Moralis reduces time-to-market with its high-level REST APIs.
- If you develop exclusively on Solana and need the deepest native chain tools (streaming, transaction submission, validator services), Helius is specifically designed for this ecosystem.
- If your use case involves des analyses complexes cross-chain Where custom query construction and deep historical data take precedence over out-of-the-box simplicity, Bitquery’s GraphQL interface provides the flexibility to ask precise questions across 40+ networks.
Most production projects evaluate at least two or three of these vendors based on their specific data needs, channel coverage, and budget constraints. Many teams also combine providers: for example, one API for aggregated market data and another for low-level RPC access. Starting with the free tiers to test integration compatibility before committing to paid plans is a pragmatic approach.
