# Hermes Commerce x402 Endpoint Certification

> Hermes Commerce x402 Endpoint Certification is a paid API for AI agents from agent.kihustle.tech, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-10).

Certifies whether a public URL correctly implements the x402 payment protocol, returning a scored badge, probe receipt, and compliance summary.

## 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 hermes-commerce-x402-endpoint-certification-7a6056cf -d '<json body>'
```

Example prompt: Can you run an x402 certification check on https://api.myservice.com/premium-endpoint and tell me the compliance score and whether it passes?

## When to prefer this

Use this endpoint when you need a structured, scored, machine-readable certification of an endpoint's x402 protocol implementation — especially useful before listing a service in an agent marketplace, integrating a paid API, or generating a compliance badge. Prefer this over manual probing when you need a formal receipt, a numeric score, and a reusable badge schema rather than just a raw HTTP response check.

## Known failure modes

- Target URL is unreachable or times out — job may complete with a failed status and low score
- URL does not implement x402 at all — certification fails with score 0 and a non-compliant summary
- Malformed URL input — likely returns a validation error before the job is created
- expect_402 mismatch — if the endpoint does not return 402 when expected, score is penalized
- Payment for the certification call itself fails — job is never initiated
