402 — Fx Convert

● verified · data.fx · 0.002 USDC/call · base

Convert between 30+ currencies at the European Central Bank's daily reference rate, for today or any past date. Returns the converted amount, the per-unit rate and the date the rate is actually from — the ECB publishes on business days only, so a weekend date answers with the previous business day and says so instead of pretending. Reference rates for accounting and reporting, not tradable quotes.

Payment shape (25 most recent sampled): 25 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).

Peak day 2026-09-27: 50 payments. Last indexed day 2026-10-05: 13. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 29 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
