> Ambolt IBAN Validate is a paid API for AI agents from api.ambolt.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-11).

Validates an IBAN string and returns parsed components including country, check digits, normalized form, and validity status.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 ambolt-iban-validate-268de668
```

Example prompt: Can you check if this IBAN is valid: DK50 0040 0440 1162 43? I want to know the country it belongs to and whether the format is correct before I send a payment.

## When to prefer this

Use this endpoint when you need a fast, pay-per-call IBAN validation with structured parsed output (country, BBAN, normalized form) without setting up a dedicated banking API account. Ideal for AI agents and developer workflows that need occasional IBAN checks as part of payment, onboarding, or data-cleaning pipelines.

## Known failure modes

- Invalid or malformed IBAN returns valid:false with parsing details
- IBAN from an unrecognized country sets countryKnown:false
- Missing required 'iban' query parameter returns an error
- IBAN exceeding 50 characters is rejected by schema validation
- Network or payment (x402) failure prevents the call from completing

## How this service works

Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.

## Output

Returns a JSON object with: valid (boolean), input (original string), normalized (no-space IBAN), grouped (space-separated IBAN), country (ISO 2-letter code), countryKnown (boolean), checkDigits, bban, length, and checkedAt timestamp.
