x402
IBAN Validator with BBAN Decomposition and BIC Check is a paid API for AI agents from tools.halowerk.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Validates an IBAN against ISO 13616/ISO 7064 with mod 97-10 checksum verification across 74 countries, decomposes BBAN into sort code and account number for 11 countries, reports SEPA membership, and optionally validates an accompanying BIC for format and country consistency.

How this service works
Prueft die IBAN nach ISO 13616 und ISO 7064 mit Pruefsumme mod 97-10 gegen die Laengentabelle von 74 Laendern, zerlegt die BBAN fuer elf Laender in Bankleitzahl und Kontonummer, meldet SEPA-Zugehoerigkeit und prueft eine mitgegebene BIC auf Format und Landesgleichheit. Trifft keine Aussage zu Existenz oder Deckung.
Output
Returns whether the IBAN is valid according to ISO 13616 and ISO 7064 mod 97-10 checksum rules, the matched country from the 74-country length table, SEPA membership status, decomposed BBAN fields (bank sort code and account number) for supported countries, and if a BIC was supplied, its format validity and whether its country code matches the IBAN. Does not verify account existence or available funds.
Example use cases
Pre-payment IBAN sanity check
“Before we send a supplier payment, validate the IBAN GB29NWBK60161331926819 and let me know if it passes the ISO checksum, what country it belongs to, and whether it's within SEPA.”
Decompose IBAN into bank and account
“Break down the IBAN FR7630006000011234567890189 into its sort code and account number components so I can fill in our internal payment form.”
Validate IBAN and BIC pair for onboarding
“We're onboarding a new vendor with IBAN NL91ABNA0417164300 and BIC ABNANL2A — can you confirm both are correctly formatted, that the BIC country matches the IBAN, and whether they're SEPA-eligible?”
Technical details
Endpoint
POSThttps://tools.halowerk.com/v1/iban/checkWhen to prefer
Choose this endpoint when you need ISO-compliant structural IBAN validation with checksum verification, SEPA status, and optional BIC cross-checking in a single call. Prefer it over simple regex checks when you need authoritative mod 97-10 verification across 74 country formats and BBAN decomposition for downstream payment system field mapping. Note it does not confirm account existence or solvency.
Side effects
- Invalid IBAN format — wrong length for the country code or non-alphanumeric characters
- Checksum failure — mod 97-10 does not equal 1
- Unknown country prefix — not in the 74-country table
- BIC country mismatch — BIC country code differs from IBAN country code
- BIC format invalid — does not conform to the standard 8 or 11 character BIC structure
- BBAN decomposition not available — country is not among the 11 supported for breakdown
