Best Crypto APIs (EVM, Solana, and More) for Developers and Traders

Blockchain development has moved well past the proof-of-concept stage. In 2026, developers and traders routinely work across multiple chains, pull wallet data from dozens of networks, and feed real-time market information into bots, dashboards, and AI agents. The common thread behind all of these workflows is a reliable crypto API.

Crypto APIs (application programming interfaces) allow software to interact with blockchain networks and market data sources programmatically. Rather than running your own nodes, indexing raw on-chain data, or aggregating prices manually, a good API abstracts that complexity into clean endpoints you can call with a few lines of code. The result: faster development cycles, lower infrastructure costs, and more time spent building the product itself.

Choosing the right API, however, depends on what you are building. Some providers focus on low-level RPC access and node infrastructure. Others specialize in aggregated market data, wallet tracking, or DeFi analytics. A few attempt to unify all of these under a single integration. The five providers below represent a cross-section of the crypto API landscape in 2026, each with a distinct approach to multi-chain data.

What to Look for in a Crypto API

Before evaluating specific providers, it helps to define the criteria that matter most when selecting a crypto data API.

• Chain coverage determines how many networks you can support through a single integration. If your product tracks wallets or portfolios across EVM chains, Solana, and Bitcoin, an API that covers all three under one schema saves significant development time compared to stitching together chain-specific providers.
• Data depth refers to how much processing the API does for you. Raw RPC data requires parsing, enrichment, and normalization before it is usable in a frontend. Higher-level APIs return balances with USD valuations, decoded transaction histories, and DeFi position breakdowns out of the box.
• Pricing model varies widely across providers. Some charge per request, others use compute units that scale with query complexity, and some offer flat monthly plans. Understanding the billing model matters, especially as usage grows.
• Documentation and developer experience affect how quickly a team can go from signup to a working integration. Well-organized docs, code samples in multiple languages, and responsive support channels reduce friction during development.

With those criteria in mind, here are five crypto API providers worth evaluating in 2026.

1. CoinStats API

Focus: Unified multi-chain data for wallets, markets, DeFi, and portfolios

The CoinStats API takes a broad approach to crypto data by combining wallet tracking, market information, DeFi position detection, and portfolio analytics into a single integration. It covers over 120 blockchains and aggregates data from more than 200 exchanges and 10,000 DeFi protocols.

Wallet data is one of the API’s core strengths. Developers can query balances and transaction histories for Solana, Ethereum and EVM-compatible chains (Polygon, Arbitrum, Optimism, Avalanche, Base, BSC, and others), and Bitcoin (including xpub/ypub/zpub extended public keys) through a consistent endpoint structure. A single call to the multi-chain balance endpoint can return token holdings across all supported EVM networks at once, which removes 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 roughly $50k in liquidity and trading volume, which means most actively traded tokens are included regardless of which chain or exchange they trade on.

DeFi positions are detected automatically across more than 1,000 protocols. Staking, lending, LP positions, and yield data appear alongside standard wallet balances without requiring separate integrations for each protocol.

For teams building AI-powered tools, CoinStats offers MCP (Model Context Protocol) support, which exposes the API’s capabilities as callable tools for AI assistants and IDE integrations like Claude Code and Cursor. This is a relatively new category of API functionality, and CoinStats is among the providers that have built first-class support for it.

Portfolio endpoints allow developers to access data already stored in a user’s CoinStats account (total value, holdings breakdown, P/L charts) via a ShareToken authentication mechanism. This is useful for building custom analytics layers, embedded portfolio widgets, or performance dashboards on top of existing CoinStats data.

Pricing: The API uses a credit-based system. A free tier provides 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 handled via an X-API-KEY header.

Consider CoinStats API if you need wallet, market, and DeFi data across many chains through one integration, or if you are building portfolio-oriented products that benefit 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 RPC (Remote Procedure Call) 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 Solana-native RPC calls) and receive raw blockchain data in return. The platform handles node management, load balancing, and uptime monitoring behind the scenes. For Solana specifically, Alchemy has invested in custom infrastructure that delivers faster archival data retrieval 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 (such as address activity or mined transactions) without polling. Smart Wallets enable embedded wallet creation with social login for both EVM and Solana. The platform also supports gasless transactions on Solana, which can improve UX for consumer-facing applications.

Where Alchemy differs from aggregated data providers is in what it returns. RPC responses contain raw blockchain state: unformatted balances, undecoded transaction data, and no built-in USD valuations or DeFi position tracking. Teams building portfolio dashboards or wallet UIs will need to add their own enrichment layer on top of the raw data.

Pricing: Alchemy uses a compute unit (CU) model. The free tier includes 30 million CUs per month. Pay-as-you-go pricing starts at $0.45 per million CUs for the first 300M CUs, then drops to $0.40 per million CUs. Enterprise plans with SLAs are available. The CU model means that costs vary depending on the complexity of your queries.

Consider Alchemy if you need performant, reliable node infrastructure for EVM or Solana development and are comfortable building data enrichment and normalization on top of raw RPC data.

3. Moralis

Focus: High-level Web3 data APIs for EVM chains and Solana

Moralis provides pre-indexed, enriched blockchain data through REST APIs designed to minimize the number of calls needed to build common Web3 features. The platform supports 19+ EVM chains and Solana, and it 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 human-readable labels already included. This means developers can display wallet contents in a frontend without writing custom parsing logic. The Token API covers real-time and historical prices across DEXs on all supported EVM chains, updated every block. The NFT API provides collection metadata, ownership data, floor prices, and marketplace trade histories.

Moralis also offers event-driven data through its Streams product. Developers can set up real-time webhooks that fire when specific on-chain events occur (token transfers, contract interactions, price changes), which is useful for building alerting systems, automated trading triggers, or live dashboards.

One area where Moralis has historically been noted as a strong fit is rapid prototyping and reducing time-to-market. The APIs are designed so that common tasks (fetching a wallet’s full portfolio, listing NFTs by owner, pulling token prices) require a single endpoint call rather than multiple RPC queries followed by manual enrichment.

The platform is SOC 2 Type 2 certified, which may matter for teams building in regulated environments or handling sensitive user data.

Pricing: Moralis uses a compute unit model. A free plan is available for development and testing. Paid plans are billed annually, with pricing that scales based on CU consumption. The average API request costs roughly 72 CUs, though this varies by endpoint. Enterprise plans with custom terms are available for high-volume use cases.

Consider Moralis if you want pre-enriched wallet and token data across EVM chains and Solana with minimal backend processing, especially for wallet apps, portfolio trackers, or NFT platforms.

4. Helius

Focus: Solana-native infrastructure, APIs, and real-time data streaming

Helius is built exclusively for the Solana ecosystem. Rather than spreading across many chains, Helius has invested deeply in Solana-specific infrastructure: optimized RPC nodes, enhanced APIs, gRPC-based data streaming, webhooks, and transaction submission tools.

At the infrastructure layer, Helius provides shared and dedicated RPC nodes with global distribution and 99.99% uptime. Staked connections are included on paid plans, which improves transaction landing rates during periods of network congestion. The platform processes hundreds of millions of RPC requests daily for clients that include 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 NFTs and fungible tokens, including metadata, ownership, and collection data. Enhanced transaction APIs decode Solana instructions and token transfers into human-readable formats, saving developers from manually parsing raw transaction data. Priority fee APIs estimate optimal fees based on real-time network conditions.

LaserStream is Helius’s gRPC-based 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 matters. Enhanced WebSockets and webhook-based event listeners provide additional real-time data options at different latency/complexity tradeoffs.

Helius also operates as one of the largest Solana validators and offers 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: Plans start with a free tier (1M credits, 10 RPC req/s). The Developer plan is $49/month with 50 RPC req/s and chat support. Business is $499/month with Enhanced WebSockets and 200 RPC req/s. Professional is $999/month with LaserStream access, 500 RPC req/s, and direct Slack/Telegram support. Enterprise plans are available for custom requirements.

Consider Helius if you are building exclusively on Solana and need deep, chain-native infrastructure with low-latency data streaming, reliable transaction submission, and Solana-specific APIs.

5. Bitquery

Focus: Multi-chain blockchain analytics via GraphQL

Bitquery takes a different approach from the other providers on this list. Instead of REST endpoints, it routes all queries through a GraphQL interface, giving developers the flexibility to request exactly the data fields they need in a single call. The platform indexes historical and real-time data across 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 trades, transfers, holder analytics, address balances, smart contract events and calls, NFT trades, and DEX activity. For trading applications, Bitquery offers a dedicated Crypto Price API that delivers pre-aggregated OHLCV data, moving averages (SMA, EMA, WMA), and cross-chain/cross-DEX price aggregation with one-second granularity.

Real-time data is available through three streaming mechanisms: GraphQL WebSocket subscriptions, Apache Kafka streams, and CoreCast gRPC streams (optimized for Solana). This range of streaming options gives teams flexibility in how they consume live blockchain data depending on their infrastructure preferences.

Bitquery also provides a Mempool API that simulates unconfirmed transactions, which is relevant for MEV detection and pre-confirmation analytics. For enterprise data teams, Bitquery integrates with cloud data warehouses (AWS S3, Snowflake, Google BigQuery, Azure, Databricks) and supports SQL access, making it possible to incorporate blockchain data into existing analytics pipelines.

The platform includes a browser-based GraphQL IDE for building, testing, and saving queries before integrating them into application code. An open-source blockchain explorer is also available.

The tradeoff 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 request. The pricing model uses a points-based system where resource-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 through custom agreements. Academic discounts are offered for students and researchers.

Consider Bitquery if you need deep, flexible on-chain analytics across many blockchains, especially for DEX trading data, holder analysis, or compliance use cases where custom query construction is an advantage.

Choosing the Right API

The providers above are not interchangeable. Each occupies a different position in the crypto data landscape, and the right choice depends on what you are building.

• If your project needs unified wallet, market, and DeFi data across many chains with minimal integration overhead, CoinStats API consolidates these categories into a single set of endpoints. It is particularly well-suited for portfolio trackers, tax tools, and multi-chain wallet applications.
• If you need low-level blockchain infrastructure with reliable RPC access for EVM chains or Solana, Alchemy provides the node layer that many production applications run on. Expect to build your own data enrichment layer on top.
• If you want pre-enriched, UI-ready Web3 data for wallets and token analytics without heavy backend processing, Moralis reduces time-to-market with its high-level REST APIs.
• If you are building exclusively on Solana and need the deepest possible chain-native tooling (streaming, transaction submission, validator services), Helius is purpose-built for that ecosystem.
• If your use case involves complex, cross-chain analytics where custom query construction and deep historical data are more important than turnkey simplicity, Bitquery’s GraphQL interface provides the flexibility to ask precise questions across 40+ networks.

Most production projects will evaluate at least two or three of these providers based on their specific data requirements, chain coverage needs, and budget constraints. Many teams combine providers as well: for example, using one API for aggregated market data and another for low-level RPC access. Starting with free tiers to test integration fit before committing to paid plans is a practical approach.
