Macropulse — Fx Convert

● verified · data.fx · 0.005 USDC/call · base

Convert an amount between currencies at the official European Central Bank reference rate. Answers "what is the USD to EUR exchange rate", "convert 250 GBP to JPY", "what was the EUR/USD FX rate on 2024-03-15". Multi-currency in one call (to=EUR,GBP,JPY), 30+ currencies, historical daily fixings back to 1999. Deterministic and cacheable: real ECB data, not a model estimate — identical inputs always return the identical rate. Keyless, sub-second.

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 2026-09-23: 334 payments. Last indexed day 2026-10-04: 6. 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 136 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
