How this service works
Official ECB foreign-exchange reference rates for agents: latest rates, conversion and historical fixings for ~30 currencies. Paid per call via x402 (USDC on Base).
Output
Returns a JSON object with the base currency, the fixing date, and a map of target currency codes to their exchange rates (e.g. {"base":"USD","date":"2026-09-24","rates":{"EUR":0.8797,"PLN":3.8553}}). Rates are sourced from ECB official daily fixings.
Example use cases
Invoice currency conversion for accounting
“I need to convert USD amounts to EUR and PLN for our monthly invoices — can you pull today's official ECB reference rates for both currencies so I can do the conversion accurately?”
Real-time FX display in a finance dashboard
“Show me the current ECB official exchange rates for GBP, CHF, JPY, and SEK against USD so I can update our finance dashboard.”
Compliance reporting with official rates
“I need the ECB's official reference rate for EUR against USD for today's date for a regulatory report — can you fetch that?”
Technical details
Endpoint
GEThttps://fx.x402utils.workers.dev/v1/rate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official ECB reference rates — the authoritative, legally recognized daily fixings used in financial, accounting, and compliance contexts — rather than real-time market rates from a broker or exchange. Ideal when you need rates for ~30 major currencies, want a simple per-call pay-as-you-go model with no subscription, and your workflow requires a trustworthy, auditable source.
Side effects
- Missing or invalid 'to' query parameter returns an error
- Unsupported currency code (outside ECB's ~30 covered currencies) returns an error or empty rates
- Payment failure via x402 (insufficient USDC balance) blocks the request
- ECB data not yet published for today (e.g. before daily fixing) may return previous business day's date
- Network or Cloudflare Worker timeout returns a 5xx error
