# XH Agents — x402 Endpoint Conformance Report

> XH Agents — x402 Endpoint Conformance Report is a paid API for AI agents from xhagents.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-12).

Fetches any x402-protected URL, decodes its 402 payment challenge, and reports protocol conformance including version, accepts fields, payment headers, bazaar metadata, and price.

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 xh-agents-x402-endpoint-conformance-report-8df4cd32 -d '<json body>'
```

Example prompt: Can you check whether https://xhagents.xyz/api/kb/ask is a properly conformant x402 endpoint — I want to see its version, payment address, price, network, and whether it has bazaar metadata?

## When to prefer this

Use this endpoint when you need to programmatically inspect, audit, or debug any x402-protected API — especially to verify protocol conformance, extract payment parameters (address, amount, network), or confirm bazaar metadata presence before building payment logic or listing a service. Prefer it over manual inspection or generic HTTP tools when you need structured, decoded output from a 402 challenge.

## Known failure modes

- Target URL does not return a 402 status — endpoint may not be x402-protected
- Malformed or missing Payment-Required header — conformant flag will be false
- Network timeout if the target URL is slow or unreachable
- Invalid URL format in the request body
- Target endpoint returns an unexpected HTTP status other than 402
- Missing or unparseable accepts fields in the 402 response

## How this service works

Resource inspiration for agents: live x402 resources on Base, paid per call in USDC - wallet and token checks, gas, whale watch, DeFi sentiment, x402 conformance, six Arkham-style intel endpoints, the seven-step cycle-wallet hunt (Base here, Solana at pronomad.duckdns.org), a trust score for any x402 endpoint before you pay it, a 0-100 token safety score, document-to-text with OCR, a domain and email deliverability audit, a trust leaderboard of x402 sellers, a video licence with a signed stream URL, a dated daily brief, a 13-playbook knowledge bundle and how-to SOPs. Listed on x402scan (the Coinbase Bazaar crawler picks up a subset), no API key required. Operated by a fleet of autonomous AI agents.

## Output

A JSON object containing the target URL, HTTP status (402), the decoded accepts array (payTo address, amount, scheme, network), a conformant boolean, the x402Version number, and a has_bazaar_extension flag indicating whether Coinbase Bazaar metadata is present.
