How this service works
Pay-per-call tools for AI agents: image generation, speech-to-text, text-to-speech, embeddings, LLM chat, website audits and contact enrichment, web page to Markdown reader, PDF to text, sitemap URLs, tech stack detection, translation, exchange rates, e-mail pre-check, domain RDAP/DNS lookup, Solana token checks, trending tokens and wallet holdings, plus business and compliance data (EU VAT/VIES, IBAN, LEI/GLEIF, US recalls, OSHA/EPA violations, UK insolvency notices). Plus prediction-market search, briefs, quotes and unsigned buy transactions, powered by Panta. Payment: x402, USDC on Base, Solana or Arc. No signup, no API key.
Output
A JSON object containing: the original input IBAN, the electronic and print-formatted IBAN, a boolean valid field, individual check results (mod97, length, structure, national), parsed components (country code, country name, bank code, branch code, account number, BBAN), expected length, and a bankLookup flag indicating whether bank-level data was resolved.
Example use cases
Pre-payment IBAN sanity check
“Before I wire funds, check whether this IBAN is valid and parse out the bank code and account number: GB29 NWBK 6016 1331 9268 19”
Bulk IBAN validation for onboarding
“I have a list of customer IBANs I need to validate in one go — can you check all of these at once: FR7630006000011234567890189, DE89370400440532013000, IT60X0542811101000000123456”
Compliance check on supplier bank details
“We just received bank details from a new supplier with IBAN NL91ABNA0417164300 — can you verify it's a valid IBAN and tell me what country and bank it's from?”

Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/iban?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate IBAN numbers before initiating a payment, during financial onboarding, or for compliance workflows. It supports batch validation of up to 50 IBANs per call, accepts messy input with spaces and dashes, and returns granular check breakdowns (MOD-97, length, structure) alongside parsed bank components. At $0.001 per call with no signup required (x402/USDC), it is ideal for lightweight automated pipelines or AI agents that need occasional IBAN checks without committing to a dedicated financial data subscription.
Side effects
- Invalid or malformed IBAN returns valid:false with specific failed check fields
- Too many IBANs in batch (over 50) may be rejected
- Missing iban or ibans query parameter returns an error
- Non-IBAN strings (e.g. SWIFT/BIC codes) will fail structure checks
- National check unavailable for some countries returns status not-available
