x402
BIC / SWIFT Code Validator is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Validates a BIC/SWIFT code offline against ISO 9362 structural rules, identifying which specific check failed on rejection.

How this service works
Validate a BIC/SWIFT code offline (ISO 9362): 8 or 11 characters, bank/country/location[/branch] layout, head-office vs branch, and the test-BIC flag. Every rejection names which check failed. Structure only — does not prove the bank is live.
Output
Returns a structured validation result indicating whether the BIC is valid or not. If invalid, the response names the specific check that failed (e.g. wrong length, invalid country code, illegal characters). If valid, it provides parsed components: bank code, country code, location code, and optional branch code, plus flags indicating whether it is a head-office BIC and whether it is a test BIC. Does not confirm whether the bank is currently active on the SWIFT network.
Example use cases
Pre-payment SWIFT code check
“Before I send an international wire, can you verify that the BIC code CHASUS33 is structurally valid and tell me if it's a head-office or branch code?”
Detecting test BICs in fintech pipeline
“I'm processing a batch of BIC codes from our onboarding form — can you check if TESTUS33XXX is flagged as a test BIC so I can filter it out?”
Debugging a rejected SWIFT format
“My bank rejected the SWIFT code BNPAFRPPXXX — can you tell me exactly which part of the structure is invalid according to ISO 9362?”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/bic-checkWhen to prefer
Use this endpoint when you need fast, offline, deterministic validation of BIC/SWIFT code structure before submitting international payments or onboarding banking data — it is ideal for catching formatting errors early without needing a live bank registry lookup. Prefer this over full bank-lookup APIs when you only need structural correctness (ISO 9362 compliance), want granular rejection reasons, or need to detect test BICs programmatically.
Side effects
- Missing 'bic' query parameter returns an error
- BIC with invalid characters causes rejection with named failed check
- BIC of wrong length (not 8 or 11 chars) returns length validation failure
- Non-ISO country code portion causes country check failure
- Malformed input string returns structured rejection with specific failure field
- Network/payment failure returns HTTP 402 or connectivity error
