Crypto Data APIs
Crypto Data APIs
Cryptocurrency Market Data From 400+ Exchanges
Access crypto market data from 400+ integrated exchanges through one normalized API ecosystem.
CoinAPI gives developers, trading firms, fintechs, researchers, and institutions access to trades, quotes, OHLCV, order books, exchange rates, indexes, assets, symbols, and market metadata without maintaining hundreds of separate exchange connections.
Work with consistent identifiers, timestamps, and schemas across exchanges and market types — from your first API request to production infrastructure.
Datasets
Everything You Need From a Crypto Data API
A cryptocurrency API should give you more than a single price. CoinAPI provides the market data needed to understand what traded, where it traded, at what price, what liquidity was available, and how the market was structured.
| Dataset | What You Get | Common Uses |
|---|---|---|
| Trades | Executed trades, price, size, timestamps and identifiers | Trading analysis, volume, order flow, backtesting |
| Quotes | Best bid and ask prices and sizes | Spread analysis, pricing, monitoring |
| OHLCV | Open, high, low, close and volume candles | Charts, indicators, analytics, research |
| Order Books | Bids, asks, depth and liquidity | Market depth, execution models, microstructure |
| Exchange Rates | Crypto-to-crypto and crypto-to-fiat reference rates | Valuation, accounting, payments |
| Indexes | Cryptocurrency benchmark and reference prices | Benchmarking, reporting, analytics |
| Assets & Symbols | Standardized metadata for exchanges, assets and instruments | Market discovery, mapping, application logic |
Instead of learning a different API structure for every exchange, your application works with a common CoinAPI data model.
Example
See the Crypto Data API in Action
CoinAPI uses normalized identifiers that describe exactly which market you are requesting.
Example: Bitcoin OHLCV
curl -H "X-CoinAPI-Key: YOUR_API_KEY" \
"https://rest.coinapi.io/v1/ohlcv/BITSTAMP_SPOT_BTC_USD/history?period_id=1HRS&limit=10"The symbol:
BITSTAMP_SPOT_BTC_USDidentifies:
- BITSTAMP — exchange
- SPOT — market type
- BTC — base asset
- USD — quote asset
A simplified OHLCV response includes fields such as:
[
{
"time_period_start": "...",
"time_period_end": "...",
"price_open": 0,
"price_high": 0,
"price_low": 0,
"price_close": 0,
"volume_traded": 0,
"trades_count": 0
}
]The same standardized approach applies across CoinAPI market data, making it easier to move between exchanges and datasets without rebuilding your internal symbol logic.

Market context
More Than a Crypto Price API
Many cryptocurrency APIs are built around one question:
That is useful, but it is not enough for many financial applications.
A market price without context does not tell you:
- where the price came from
- what actually traded
- what buyers are bidding
- what sellers are asking
- how much liquidity is available
- how deep the market is
- whether prices differ across exchanges
CoinAPI provides the underlying market data needed to answer those questions.
Crypto Trades API
Access executed cryptocurrency trades with price, size, timestamps, and exchange information.
Use trade data for volume analysis, quantitative research, market monitoring, strategy development, and transaction-level analysis.
Crypto Quotes API
Retrieve bid and ask information from supported markets.
Quotes help applications measure spreads, monitor pricing, analyze liquidity, and understand the market available before a trade occurs.
Crypto OHLCV API
Access standardized cryptocurrency candle data across supported markets and periods.
OHLCV is suited to charting, technical analysis, indicators, dashboards, research, and many backtesting workflows.
Crypto Order Book API
Access bids, asks, market depth, and liquidity information.
Order book data provides a more detailed view of market structure for execution analysis, liquidity research, trading applications, and quantitative models.
Crypto Exchange Rates API
Retrieve real-time and historical crypto-to-crypto and crypto-to-fiat exchange rates calculated using CoinAPI's VWAP-24H methodology across selected market data sources.
Use exchange rates for valuation, accounting, payments, treasury systems, reporting, and applications that need a reference rate rather than one exchange-specific quote.
Crypto Indexes API
Access benchmark and reference prices for cryptocurrency markets.
Indexes can support portfolio valuation, benchmarking, market analysis, reporting, and other institutional workflows.
Access
Choosing the Right Delivery Method
The same normalized market data can be accessed through multiple interfaces depending on your application. The best delivery method depends on your workflow, not on the data itself.
REST APIs
REST APIs are designed for targeted requests, historical queries, and applications that retrieve data on demand.
WebSocket APIs
WebSocket APIs provide continuous real-time market updates as events occur.
WebSocket DS
WebSocket DS delivers lower-latency direct-source market streams for latency-sensitive trading infrastructure.
Flat Files
Flat Files provide bulk historical datasets for offline analytics, AI training, and large-scale research.
FIX
FIX supports institutional market data and trading workflows that require standardized financial messaging.
Normalization
Standardized Crypto Market Data
The value of a multi-exchange API is not only the number of exchanges connected. The data also needs to be usable together.
CoinAPI standardizes core market information across its ecosystem, including:
- Exchange identifiers
- Asset identifiers
- Symbol identifiers
- Base and quote assets
- Market types
- Timestamps
- Trade structures
- Quote structures
- OHLCV structures
- Order book data
That makes it possible to query different venues without writing completely different downstream logic for each exchange. It also makes cross-exchange analysis significantly easier.
For example, a research system comparing BTC markets across multiple venues can use standardized identifiers and schemas instead of maintaining a separate translation layer for every exchange.
Lifecycle
Built for the Entire Development Lifecycle
Most cryptocurrency applications rely on more than one delivery method. A quantitative trading strategy might begin with years of historical market data, move into paper trading with live market streams, and eventually become a production trading system powered by real-time data and execution infrastructure. CoinAPI supports every stage of that application.
| Stage | Typical workflow | CoinAPI products / access methods |
|---|---|---|
| Research | Explore markets, analyze historical data, and evaluate datasets | Market Data API via REST, Flat Files |
| Backtesting | Validate strategies using large historical datasets | Flat Files, Market Data API via REST |
| Development | Build and test applications with metadata, historical snapshots, and live market data | Market Data API via REST and WebSocket |
| Production market data | Power live dashboards, alerts, trading systems, and real-time infrastructure | Market Data API via WebSocket, WebSocket DS, and FIX where applicable |
| Production trading / execution | Manage orders, balances, positions, executions, and routing across supported venues | EMS Trading API via WebSocket or FIX |
| Reporting & valuation | Support portfolio valuation, benchmarking, accounting, and reference pricing | Exchange Rates API, Indexes API, Market Data API via REST |
Because CoinAPI products use consistent identifiers, metadata, and platform conventions across market data, exchange rates, indexes, and trading workflows, teams can move between research, development, production, and reporting with less integration work.
Integrations
One API Instead of Hundreds of Exchange Integrations
Connecting directly to one exchange is simple. Connecting to dozens or hundreds means handling different APIs, WebSocket implementations, symbol formats, timestamps, market structures, schemas, and exchange-specific changes. CoinAPI handles that normalization layer.
