Currency Exchange Rates + Converter (no key)

Live and historical currency exchange rates and conversion, using official European Central Bank reference rates (via Frankfurter), behind a clean HTTP API (and MCP tool). Get the latest rates, convert an amount between currencies, look up rates on a past date, or pull a daily time series — across ~31 major currencies. No API key, no rate limits. Pay per query.

• 💱 Convert — turn an amount from one currency into another at the current rate.
• 📊 Latest / historical — current rates or rates on any past date, for a base against chosen symbols.
• 📈 Time series — daily rates over a date range (great for charts and trends).
• 🏦 Official ECB rates — the reference everyone trusts, updated each working day.
• 💵 Pay per query · no key.

The use case it was built for

Pricing pages, invoices, dashboards, accounting and agents constantly need "how much is X in Y?" and "what was the rate on this date?". This API answers both with authoritative ECB data — no key, no limits to manage.

Sample output (convert, 100 USD → EUR)

{ "ok": true, "from": "USD", "to": "EUR", "amount": 100, "rate": 0.8726, "result": 87.26, "date": "2026-09-18" }

How to use

• HTTP API (Standby): POST or GET /latest, /convert, /historical, /timeseries, /currencies. GET / returns help. Example: GET /convert?from=USD&to=JPY&amount=250.
• Normal run: pass { operation, from, to, amount }; results land in the dataset + key-value store.
• MCP tool: expose it to your agent via Apify's MCP server.

Input

• operation — latest · convert · historical · timeseries · currencies.
• from — base/source currency (3-letter). to — target (convert). amount — for convert.
• symbols — target currencies for latest/historical/timeseries (comma-separated; empty = all).
• date — for historical. start / end — for time series.

Pricing

Per query from $0.004 (down to $0.0015 on higher tiers). One call = one query (which can return many currencies or many days at once).

Notes & limits

Rates are ECB reference rates (mid-market), not live trading or card rates. History goes back to 1999 for most currencies.
