How this service works
Get daily reference exchange rates per one unit of a base currency, with observation date and currency codes. Not executable trading quotes. ECB source data is also available free from ecb.europa.eu.
Output
A JSON object containing the service name, subject, retrieval timestamp (ISO 8601), source attribution (ECB name and URL), and a report object with the base currency code, observation date, amount (1 unit), a map of all available currency codes to their rates relative to the base, and a notice (e.g. disclaiming these are reference rates, not executable trading quotes).
Example use cases
Daily FX rates for financial reporting
“Can you pull today's ECB reference exchange rates with USD as the base currency so I can update our financial report with official daily rates?”
Currency conversion for invoice pricing
“I need to know the current ECB reference rates for EUR against all other currencies to price our international invoices correctly — can you fetch those?”
Historical rate check for compliance
“What was the ECB daily reference exchange rate for GBP as the base currency today? I need the official rate and the observation date for our compliance audit.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/data/exchange-rates?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official ECB daily reference exchange rates for bookkeeping, financial reporting, compliance, or informational lookups — not for live trading quotes or real-time market prices. Prefer this over scraping ecb.europa.eu directly when you want a structured JSON response with source attribution and a retrieval timestamp, and when you need it in an agent workflow that supports x402 micropayments.
Side effects
- Unsupported or invalid currency code (base not in ECB feed) — likely returns an error or empty rates
- ECB source data temporarily unavailable — may return stale or error response
- Malformed query parameter — schema validation error
- Rate limit or payment failure — 402 response if x402 payment not processed
