}Why FXRATE-API
Three things today's exchange rate APIs get wrong — and how we fix them.
5,000 requests/month free — with any base currency, not just EUR. Paid plans start at $5/mo, half the competition's entry price.
One JSON block plugs FXRATE-API into Claude, ChatGPT, or Cursor. Tool descriptions guide the agent to pick reference vs. market rates correctly.
Every rate is graded official or market grade, with the exact timestamp. Finance and compliance teams love this.
Powered by Cloudflare Workers + a serverless edge database. p99 under 150ms in every major region, 0ms cold start.
Typed TS & Python SDKs ship from day one. Clear error codes, every one with a how_to_fix.
Hit your cap? We return 429 — never a silent charge. Dashboard alerts at 80% and 100%.
MCP · Model Context Protocol
Drop one JSON block into Claude Desktop, Cursor, or ChatGPT and your agents get four carefully described tools —
get_latest_rate, convert_amount,
get_historical_rate, get_timeseries. Every description tells the model when to use reference vs. market rates.

why + how_to_fix{ "EUR": 0.923, "JPY": 152.14, "GBP": 0.791 }Reference rates come from official central-bank and government statistical sources. Market rates on paid plans come from licensed aggregators. Every response is graded official or market and stamped with an exact timestamp.
No. FXRATE-API provides reference and indicative market rates for display, accounting, reporting, and AI agent use. It is not a trading venue and not financial advice.
We email you at 80% and 100% of quota. Up to 110% you get a soft grace with a warning header. Above that, we return HTTP 429 — no silent overage charges, ever.
No. One fxr_* key works for both. Pro and Business plans can issue scoped private keys for team members and agents.
