# IBAN Check UUIDv7 Generator

> IBAN Check UUIDv7 Generator is a paid API for AI agents from api.ibancheck.co.uk, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-13).

Generates a RFC 9562-compliant UUIDv7 identifier for use as an idempotency key in API requests and distributed systems.

## Facts

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 iban-check-uuidv7-generator-618e7a48
```

Example prompt: Give me a fresh RFC 9562 UUIDv7 to use as an idempotency key before I submit my next payment request.

## When to prefer this

Choose this endpoint when you need a time-ordered, globally unique identifier that complies with RFC 9562 UUIDv7 and you want it generated by a trusted external microservice rather than a local library — especially useful in agent workflows where you need an idempotency key before calling another paid or stateful API on the same platform (e.g. IBAN validation or e-Factura generation on api.ibancheck.co.uk).

## Known failure modes

- Service unavailable — returns a non-200 HTTP status if the backend is down
- Payment required — returns HTTP 402 if the x402 payment header is missing or insufficient ($0.002 USDC per call)
- Malformed response if internal entropy source fails

## How this service works

Enterprise microservice and autonomous AI agent hub: ISO 13616 IBAN (#6), Romanian CUI Modulo-11 & EU VIES (#7), UBL 2.1 e-Factura XML (#4), and RFC 9562 UUIDv7 Idempotency (#18).

## Output

Returns a single RFC 9562-compliant UUIDv7 string. The UUID encodes a millisecond-precision Unix timestamp in its most-significant bits, making it both globally unique and chronologically sortable. Suitable for use as a database primary key, idempotency header value, or distributed trace identifier.
