How this service works
Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.
Output
A JSON object containing a valid_format boolean indicating whether the BIC passes ISO 9362 structural checks, a country field (2-letter ISO country code extracted from the BIC), and a bank_code field (the 4-character bank identifier prefix). Note this is format validation only — it does not confirm the BIC exists in any live directory.
Example use cases
Wire transfer pre-flight check
“Before I send this international wire, can you validate that CHASUS33 is a properly formatted SWIFT BIC code and tell me what country it's from?”
Fintech onboarding BIC screening
“A user just entered BNPAFRPPXXX as their bank's SWIFT code during signup — is that a valid BIC format, and can you pull out the bank code and country?”
Payment data quality audit
“I have a BIC code HBUKGB4B from my records — can you confirm it's correctly formatted according to ISO 9362 and tell me what it decodes to?”
Technical details
Endpoint
POSThttps://agent402.co.uk/v1/validate/bicWhen to prefer
Use this endpoint when you need fast, cheap, format-level validation of a BIC/SWIFT code (ISO 9362) before processing a payment or onboarding a user — it confirms structural correctness and extracts country/bank components without requiring a live directory lookup. Prefer it over a full directory service when you only need to catch typos or malformed codes rather than confirm the institution exists.
Side effects
- BIC is malformed (wrong length, invalid characters) — returns valid_format: false
- Missing or empty bic field in request body — likely 400 error
- BIC passes format check but is not a real registered code — endpoint will still return valid_format: true since it only validates format
- Network or service unavailability — HTTP 5xx
- Payment not included — HTTP 402 payment required
