How this service works
Pay-per-call API for AI agents with no signup or API key. Email validation, SPF/DMARC audits, DNS lookup, site contacts, URL to Markdown, IBAN and Swedish personnummer/orgnr validation. From $0.001 in USDC on Base via x402.
Output
A JSON object containing: `valid` (boolean), `errors` (array of validation error strings, empty if valid), `country` (ISO 3166-1 alpha-2 country code), `check_digits` (2-digit string), `bban` (Basic Bank Account Number string), `formatted` (space-grouped IBAN string, e.g. 'GB82 WEST 1234 5698 7654 32'), and `normalized` (compact IBAN without spaces).
Example use cases
Pre-payment IBAN verification
“Before I wire money to this account, can you verify that GB82 WEST 1234 5698 7654 32 is a valid IBAN and tell me what country it's from?”
Batch data cleanup for finance team
“We imported a spreadsheet of supplier bank accounts and I need to check whether DE89 3704 0044 0532 0130 00 is a valid IBAN — can you parse it and flag any errors?”
User input validation in checkout flow
“A customer entered 'FR7614508711517 1573956913' as their IBAN — can you validate it and give me the normalized form so I can store it correctly?”

Endpoint
GEThttps://agentkit-x402.zenith-ops.workers.dev/v1/iban?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, no-signup, pay-per-call IBAN validation with structured output including country, BBAN, and formatting — especially in agent workflows where managing API keys is impractical. Prefer it for one-off or low-volume checks billed in USDC micro-payments via x402 on Base.
Side effects
- Missing `iban` query parameter returns an error response
- Completely malformed input (non-IBAN string) returns valid=false with descriptive errors array
- Unknown or unsupported country code may return valid=false
- Payment not included or insufficient USDC triggers x402 payment-required response (HTTP 402)
- Network timeout on Cloudflare Worker edge
