● unverified · compute.tools · 0.002 USDC/call · base

Validate an IBAN offline: country registry length, structure, and the ISO 7064 mod-97 checksum that catches what humans and spreadsheets actually get wrong — a transposed pair, a dropped character, an O typed for a zero. Returns the normalised and print-formatted forms, country, SEPA membership, and the bank identifier where the layout is known. Every rejection names WHICH check failed, so you know whether to fix the row or drop it. Structure only: a valid IBAN is not proof the account exists.

Checked 2 times without a pass yet. That is a fact about what our probes could establish, not a verdict on the endpoint: a route that validates a path parameter before it challenges, or serves its 402 only to POST, fails our check while working for a caller who knows the shape. The listing record shows what the probes found.

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 2026-10-08: 87 payments. Last indexed day 2026-10-09: 50. 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 39 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
