CoinAPI is a cryptocurrency market data infrastructure company.
We collect, normalize, store, and distribute cryptocurrency market data from exchanges around the world, making it available through a single, consistent platform.
Instead of maintaining dozens of exchange integrations, handling changing APIs, mapping symbols, storing historical data, and managing market data infrastructure, developers connect to CoinAPI and access everything through one unified ecosystem.
Whether you're building a trading platform, portfolio tracker, brokerage, exchange, AI agent, research platform, custody solution, tax application, or institutional trading system, CoinAPI provides the data foundation.
Crypto Market Data Is Harder Than It Looks
- Every exchange has different APIs.
- Every venue uses different symbol formats.
- Historical coverage varies.
- Data quality differs.
- Infrastructure fails.
- Integrations break.
For a single exchange, this may be manageable. For twenty exchanges, it becomes a full-time engineering challenge.
CoinAPI eliminates that complexity.
Why Leading Firms Choose CoinAPI

SDKs in 15+ languages, detailed documentation, open-source examples, transparent pricing, technical onboarding resources, and developer-focused support.
AI and MCP Ready
Access market data through REST APIs, JSON-RPC interfaces, and Model Context Protocol (MCP) servers.
Why Not Connect Directly to Exchange APIs?
- Many teams start with a single exchange integration.
- Then they need five.
- Then twenty.
- Then historical storage.
- Then symbol normalization.
- Then monitoring.
- Then data quality controls.
- Then maintenance.
Building and maintaining market data infrastructure quickly becomes more expensive than the application you're trying to build.
CoinAPI handles the infrastructure so your team can focus on building products.
