What Is CoinAPI?

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.

One integration.One schema.One platform.Hundreds of exchanges.

Why Leading Firms Choose CoinAPI

One Integration for Hundreds of Exchanges

Access spot, perpetuals, futures, options, indexes, and exchange rates through a single platform.

No exchange-specific implementations.
No custom parsers.
No symbol mapping nightmares.

Real-Time and Historical Data in One Ecosystem

Stream real-time trades, quotes, and order books while accessing more than a decade of historical cryptocurrency market data from the same platform.

Built for Reliability

Our infrastructure is designed for institutions that require predictable performance, global availability, and enterprise-grade support.

99.9% SLA-backed uptime
Global low-latency infrastructure
Redundant architecture
Dedicated enterprise support
Secure delivery methods

Built by Developers for Developers

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 Build It Yourself?

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.
