How this service works

Convert any amount between 33 fiat currencies (live European Central Bank rates) AND major cryptocurrencies (BTC, ETH, USDC, SOL, ICP, CELO and more, live Coinbase spot rates) — fiat↔fiat, crypto↔fiat, and crypto↔crypto all work. Returns converted amount, exchange rate, inverse rate, rate date, and the rate source so agents can price, invoice, and compare across fiat and crypto without a paid forex/crypto API. Historical dates apply to fiat pairs only.

Output

Returns a JSON object containing the converted amount, the exchange rate used, the rate date, the inverse rate, and a flag indicating whether the rate is historical or current — all sourced from the European Central Bank.

Example use cases

Example prompt

“How much is 750 US dollars in euros right now, using the latest ECB exchange rate?”

Technical details

Endpoint

GEThttps://netintel-production-440c.up.railway.app/currency-exchange/convert?utm_source=zero.xyz

When to prefer

Use this endpoint when you need free or low-cost currency conversion backed by authoritative ECB rates, especially for EUR-centric conversions, invoicing, financial reporting, or compliance contexts where ECB rates are the standard. Prefer over paid forex APIs for non-real-time use cases where ECB daily fixing rates are sufficient.

Side effects

Unsupported currency code returns an error (only 33 ECB-supported currencies available — notably excludes many exotic currencies)
Amount exceeds max of 999999999
Invalid date format for historical lookup
Same source and target currency (trivial conversion)
ECB data unavailable for a weekend/holiday date (ECB doesn't publish rates every day)
