{"slug":"iban-check-75810109","name":"IBAN Check","summary":"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.","status":"live","indexable":true,"listed_since":"2026-10-28T09:21:13.254165Z","sources":[{"source":"x402_bazaar","external_id":"https://402.com.tr/api/x402/iban-check","owner_address":"0x973a31858f4d2125f48c880542da11a2796f12d6","seen_at":"2026-10-30T18:38:33.985804Z","removed_at":null}],"endpoints":[{"url":"https://402.com.tr/api/x402/iban-check","host":"402.com.tr","protocol":"x402","state":"live","last_probe_at":"2026-10-30T18:43:53.966399Z","last_ok_at":"2026-10-30T18:43:53.966399Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"402-com-tr-8c934a76","name":"402.com.tr"}],"payment_options":[{"endpoint_url":"https://402.com.tr/api/x402/iban-check","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"2000","pay_to":"0x973a31858f4d2125f48c880542da11a2796f12d6","observed_at":"2026-10-30T18:43:53.966399Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":7,"paid_calls_30d":8,"last_paid_at":"2026-10-30T13:02:20.929Z","reported_at":"2026-10-30T18:38:33.985804Z"},"assessment":{"method":"2026.10.2","checks":[{"id":"answers","state":"pass","reason":"Answered a check 5 hours ago."},{"id":"owner","state":"fail","reason":"No one has proven control of its domain or of the wallet it is paid at."},{"id":"track_record","state":"fail","reason":"Listed for 2 days; 30 are needed."},{"id":"real_customers","state":"fail","reason":"7 different wallets paid it in 30 days, as the x402 Bazaar reports (not yet counted by addrbook); 10 are needed."},{"id":"clean_scan","state":"not_applicable","reason":"Not an MCP server."}],"passed":1,"applicable":4,"contradicted":false,"computed_at":"2026-10-31T00:27:10.130684Z"},"identity":{"endpoint_domains":["402.com.tr"],"proven_domains":[],"proven_wallets":[],"namesakes":[{"slug":"iban-check-9a342fd5","name":"IBAN check","proven_domain":null}],"namesake_count":1,"identity_checks":[],"wallet_attestations":[{"wallet":"0x973a31858f4d2125f48c880542da11a2796f12d6","provider":"coinbase_account","attestation_uid":"0xe82bea8110441a05a62d3027109153e2f88220816a27f96781981529c201ea3d","attested_at":"2025-09-26T08:09:05Z","checked_at":"2026-10-26T20:26:45.762462Z"}],"human_backings":[]},"replies":[],"customers":null,"scan":null,"notice":"Not affiliated with addrbook — claim or request removal."}
