Developer integration paths

Build with REST, code samples, or MCP

Start with familiar REST endpoints and SDK-friendly JSON. Use MCP as an additional path when teams want exchange-rate tools inside LLM clients.

View REST docs Code samples

REST API endpoints

Call /latest, /convert, /historical, /timeseries, and /currencies from any backend or app.

Code samples and SDK-ready JSON

Use documented request patterns and lightweight JSON responses that work cleanly with PHP, JavaScript, and server-side SDK wrappers.

MCP for AI clients

Connect Claude, ChatGPT, Cursor, VS Code, Codex, and other MCP-compatible clients using the same account and quota.

Example developer workflow

Fetch live USD rates, convert checkout totals, and chart 90-day movement with the REST API.
