# Greeneris IBAN Validator

> Greeneris IBAN Validator is a paid API for AI agents from data.greeneris.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Validates an IBAN string offline using format regex, country-specific length rules, and ISO 7064 mod-97 checksum, returning validity, country code, BBAN, and failure reason

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 greeneris-iban-validator-e80bd1ac
```

Example prompt: Can you check whether this IBAN is valid before I send the transfer: FR1420041010050500013M02606?

## When to prefer this

Use this endpoint when you need a fast, cheap, deterministic IBAN pre-validation before initiating a SEPA or international bank transfer, and you don't want to hit a live bank registry API. It covers ~85 countries per the public SWIFT registry, validates both format and ISO 7064 mod-97 checksum, accepts messy input with spaces or dashes, and costs only $0.001 USDC — ideal as a guard-check before more expensive downstream operations.

## Known failure modes

- Missing 'iban' query parameter — returns 400 or error response
- Unrecognised country prefix not in SWIFT registry of ~85 countries — returns valid=false with reason
- IBAN fails mod-97 checksum — returns valid=false with checksum failure reason
- IBAN has wrong length for its declared country — returns valid=false with length mismatch reason
- Payment not included or insufficient — 402 Payment Required

## How this service works

Deterministic IBAN check before a SEPA/international transfer: format regex, per-country length (public SWIFT registry, ~85 countries) and ISO 7064 mod-97 checksum. Query: ?iban=FR1420041010050500013M02606 (spaces/dashes tolerated). Returns valid, country, bban, and a precise failure reason. Pure offline computation, 1y cache.

## Output

Returns a JSON object with a boolean 'valid' field, the detected 'country' (2-letter ISO code), the parsed 'bban' (Basic Bank Account Number), and a precise 'failure reason' string if the IBAN is invalid — e.g. wrong length for the country, failed mod-97 checksum, or unrecognised country prefix. Spaces and dashes in the input are tolerated and stripped automatically. Response is cacheable for 1 year since the computation is purely deterministic.
