How this service works
Use when an agent needs the ECB's official euro reference rates straight from the source file — EUR base, latest day or any date in the last 90 days, one currency or the full table. Complements the Frankfurter-based FX endpoints with the primary publication. Use permitted: build it into your products and services, paid or free. Raw redistribution of the feed itself is prohibited.
Output
Returns ECB official euro reference rates: either a single currency rate (e.g. EUR/USD = 1.0823) or the full table of all published rates, for the requested date or latest available publication, along with the reference date of the data.
Example use cases
Display today's full ECB rate table
“Pull the full ECB euro reference rate table for today — I want to see all currencies.”
Look up historical ECB rate for a past date
“What was the official ECB euro reference rate for GBP on 2025-02-14?”
Single-currency rate for invoicing
“I need the ECB official EUR to CHF rate for today so I can use it on an invoice.”
Technical details
Endpoint
GEThttps://pay.brianbooms.com/api/v1/data/ecb?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the authoritative ECB official euro reference rate — the primary publication from the source — rather than derived or aggregated FX data from providers like Frankfurter, Fixer, or OXR. Ideal when regulatory compliance, invoicing, or official financial reporting requires citing the ECB source directly. Best for EUR-base lookups; if you need a non-EUR base currency, use the complementary Frankfurter-based FX endpoint instead.
Side effects
- Date outside 90-day window returns an error or empty result
- Invalid or unsupported currency code returns no rate for that pair
- ECB feed temporarily unavailable causes upstream fetch failure
- Date falls on a weekend or ECB holiday when no rates are published
