Why FXRATE-API

Honest pricing. AI-native. Audit-ready.

Three things today's exchange rate APIs get wrong — and how we fix them.

3.3× the free tier

5,000 requests/month free — with any base currency, not just EUR. Paid plans start at $5/mo, half the competition's entry price.

Native MCP on day one

One JSON block plugs FXRATE-API into Claude, ChatGPT, or Cursor. Tool descriptions guide the agent to pick reference vs. market rates correctly.

Source attribution built-in

Every rate carries its origin — ECB, FRED, or market aggregate — with the exact timestamp. Finance and compliance teams love this.

Edge-fast globally

SDKs that feel like Stripe

Typed TS & Python SDKs ship from day one. Clear error codes, every one with a how_to_fix.

No overage surprises

Hit your cap? We return 429 — never a silent charge. Dashboard alerts at 80% and 100%.

MCP · Model Context Protocol

Your AI agents already know
how to use FXRATE-API.

Drop one JSON block into Claude Desktop, Cursor, or ChatGPT and your agents get five carefully described tools — get_latest_rate, convert_amount, get_historical_rate, get_timeseries, list_sources. Every description tells the model when to use reference vs. market rates.

Hosted at mcp.fxrateapi.com — no self-hosting required
Same API key as the REST API — one bill, one usage meter
Also available as npx @fxrateapi/mcp or uvx fxrateapi-mcp

      "headers": {
        "Authorization": "Bearer fxr_live_..."
      }
    }
  }
}

Try it: in Claude, ask "Convert 100 USD to EUR at yesterday's ECB reference rate".

Side by side

Built to replace exchangerate-api.

Better free tier, lower paid entry, and features the incumbent just doesn't ship.

Pricing benchmarks as of 2026-04. exchangerate-api remains a fine tool — we just think developers deserve more for less.

Frequently asked

Where do your rates come from?

Reference rates come from ECB (via Frankfurter + direct SDMX) and FRED. Market rates on paid plans come from licensed aggregators. Every response is labeled with its exact source and timestamp.

Is FXRATE-API suitable for trading?

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.

What happens when I hit my monthly cap?

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.

Do I need two keys for HTTP and MCP?

No. One fxr_* key works for both. Pro and Business plans can issue scoped private keys for team members and agents.

Which historical range do you cover?

Our archive covers euro-area currencies from 1999 and the rest of the world from 2000. How far back you can query depends on plan: Free gets the last 30 days, Hobby gets 5 years, Pro & Business get full depth. Business also includes a 30-day minute-level intraday archive with CSV / Parquet bulk export. Tick-level historical market data is on the V2 roadmap.
