data
European Central Bank daily reference FX rate for any fiat currency pair, plus its inverse and the rate date. Pay per call in USDC on Base via x402 — no account, no API key, no subscription. Settlement is proof-gated: the rate and its inverse must multiply to 1 within 1e-6 or you are not charged. Every settled call includes a free cryptographically anchored hash receipt with a verify_url you can check without trusting us.
