Technical details
Endpoint
GEThttps://pennydatahq.com/api/fx/%7Bcurrency%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an official, authoritative ECB euro foreign exchange reference rate for a single currency, without needing an API key or account — particularly in automated agent workflows that can pay per call in USDC via x402. Prefer this over bank or broker FX feeds when regulatory-grade ECB reference rates are required for reporting or compliance purposes.
Side effects
- Unsupported or misspelled currency code returns an error or empty result
- ECB has not yet published today's rate (rates published on business days only), so weekend/holiday queries may return previous business day data
- Payment failure via x402 prevents the call from completing
- Network timeout reaching pennydatahq.com
