Developer tools
The same central-bank rate data behind this site, packaged for machines: a REST API, an MCP server for AI assistants, and — coming soon — webhook subscriptions that push new rates to you instead of you polling for them.
REST API
api.banks-rates.com Public JSON API at api.banks-rates.com. Rates, cross-rates, historical series and bank metadata for every tracked central bank — no key required, CORS open, full archive.
API documentation →MCP server
mcp.banks-rates.com Streamable HTTP MCP server at mcp.banks-rates.com. Add one URL to Claude, Cursor or any MCP-compatible client and your AI assistant queries official rates directly.
MCP documentation →Webhook subscriptions
Subscribe to a bank or a currency and get an HTTP callback the moment new rates are ingested — no polling, no cron jobs on your side.
In development. Write to us if you'd like early access or want to shape the payload format.
Request early access →API keys
Everything works anonymously at the base per-IP limits. Sign in to the console to issue a free API key and lift the limits — the same key works for both the REST API and the MCP server.
Limits and plans
Anonymous and keyed access are both free; they differ only in rate limits. The full table is on the pricing page.
Frequently asked questions
Do the API and the MCP server return the same data?
Yes. The MCP tools forward to the same /v1 endpoints, so numbers, dates and fallback behaviour are identical across both surfaces.
Do I need an API key?
No — everything works anonymously at per-IP limits. A free key from the console raises the limits and ties them to the key instead of the IP.
When are webhook subscriptions launching?
They are in development. Email us with your use case and we'll offer early access when the endpoint is ready.
