The Exchange Rates API Built for Trading
Get real-time and historical crypto-to-fiat rates updated every 100 ms from 400+ exchanges - with VWAP-based pricing you can trust.
What data will you get?
Single-Pair Exchange Rates
Retrieve current or historical exchange rates for any supported base and quote asset pair. Each response includes timestamp, base asset, quote asset, and rate.
All Rates for One Base Asset
Get exchange rates from one base asset to many quote assets in a single response. Results can be filtered by asset IDs or inverted when needed.
Historical Rate Snapshots
Access point-in-time exchange rates for a selected asset pair. This is useful for historical conversions, reporting, and portfolio valuation.
Exchange Rate Time Series
Retrieve historical OHLC exchange-rate candles for a selected asset pair. Data includes open, high, low, and close rates across defined time periods.
Multiple Period Granularities
Request historical rate series using periods from seconds to days. Supported intervals include second-, minute-, hour-, and day-based periods.
VWAP-Based Rate Values
Rates are calculated using a 24-hour rolling VWAP methodology. This helps provide representative pricing across multiple market data sources.
Realtime WebSocket Rates
Subscribe to live exchange-rate updates through a persistent WebSocket connection. Streams can be filtered by asset or asset pair.
Rate Type Information
Receive rate type details that explain how each exchange rate was produced. This includes isolated pair rates and cross-based reference calculations.
Asset Metadata
Access supported fiat and crypto asset details before requesting rates. Metadata can include asset name, type, coverage dates, USD price, and chain addresses.
Asset Icons
Retrieve asset icon URLs in supported sizes for use in apps, dashboards, asset selectors, and watchlists.

Exchange Rates API's Key Features
Live & Historical Data
Use the same API to retrieve live rates or query historical data. This simplifies workflows across analytics, reporting, and trading systems.
VWAP-24H Methodology
Rates are calculated using aggregated market activity across multiple venues. This helps reduce noise from low-liquidity sources.
AI-Ready via MCP
Integrate directly with AI agents and tools using MCP endpoints. No custom wrappers or additional infrastructure required.
Broad Market Coverage
Track 150+ fiat currencies and 10,000+ digital assets from 400+ exchanges, all normalized into one consistent data feed.
Flexible Delivery Options
Choose between REST, WebSocket, JSON-RPC, or MCP depending on your architecture. Each interface supports different use cases without changing the data model.
Consistent Data Schema
All endpoints use the same structure for assets, rates, and timestamps. This reduces transformation work across systems.
Low-Latency Streaming
WebSocket delivery is optimized for real-time applications. Designed for fast updates and continuous data flow.
Reliable Infrastructure
Built for high availability and stable performance. Suitable for production systems that require consistent data access.
Rate Transparency
Rate types and timestamps provide visibility into how each value is calculated. This supports validation and audit workflows.
