{"slug":"2s-d8a636f8","name":"2s","summary":"Validate an International Bank Account Number (IBAN) with full ISO 13616 checks: country-specific length and the ISO 7064 mod-97 checksum (not just a regex). Returns {valid, iban (normalized), formatted (4-char groups), countryCode, checkDigits, bban, reason}. Catches transposed digits and wrong-length accounts that a format check misses, and returns the canonical form so a glue/ETL pipeline can validate AND normalize bank details in one deterministic call. ~85 countries. No bank directory lookup — structure + checksum only.","status":"live","headings":[{"slug":"banking-tax","title":"Banking, tax & accounting"}],"indexable":true,"listed_since":"2026-10-25T17:53:37.864367Z","sources":[{"source":"x402_bazaar","external_id":"https://2s.io/api/validate/iban","owner_address":"0x2b6d4988db4723e6908db86ab2b8dfbc51fc32c5","seen_at":"2026-11-15T10:34:15.297029Z","removed_at":null}],"endpoints":[{"url":"https://2s.io/api/validate/iban","host":"2s.io","protocol":"x402","state":"live","last_probe_at":"2026-11-15T12:00:09.622993Z","last_ok_at":"2026-11-15T12:00:09.622993Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"2s-io-49c1cd49","name":"2s.io"}],"payment_options":[{"endpoint_url":"https://2s.io/api/validate/iban","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"2500","pay_to":"0x2b6d4988db4723e6908db86ab2b8dfbc51fc32c5","observed_at":"2026-11-15T12:00:09.622993Z"},{"endpoint_url":"https://2s.io/api/validate/iban","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","scheme":"exact","rail":"exact","asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","coin":"USDC","asset_label":"USDC","amount":"2500","pay_to":"TW6ntaGzvj63ZgPjszd4FCGmVTGfzv1MAYZbjYcyWhn","observed_at":"2026-11-15T12:00:09.622993Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":2,"paid_calls_30d":2,"last_paid_at":"2026-11-01T07:47:18.158Z","reported_at":"2026-11-15T10:34:15.297029Z"},"assessment":{"method":"2026.11.4","checks":[{"id":"answers","state":"pass","reason":"Answered a check 1 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 20 days; 30 are needed."},{"id":"real_customers","state":"fail","reason":"2 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":"2026-11-15T00:31:29.782454Z"},"identity":{"endpoint_domains":["2s.io"],"proven_domains":[],"proven_wallets":[],"namesakes":[],"namesake_count":0,"identity_checks":[],"wallet_attestations":[],"human_backings":[]},"replies":[],"customers":null,"scan":null,"notice":"Not affiliated with addrbook — claim or request removal."}
