> SiteCheck IBAN Validator is a paid API for AI agents from api.sitecheck-api.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sitecheck-iban-validator-2b77a79e
```

Example prompt: Can you validate this IBAN for me — DE89 3704 0044 0532 0130 00 — and tell me if it's valid, which country and bank it belongs to, and what the account number is?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
