# CryptoFeed402 Agent-Ready Site Audit

> CryptoFeed402 Agent-Ready Site Audit is a paid API for AI agents from cryptofeed402.site, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-21).

Audits a public website for AI-agent readiness (llms.txt, HTTPS, headers, etc.) and returns a scored report with pass/warn/fail checks.

## Facts

- Endpoint: GET https://cryptofeed402.site/audit/agent-ready?utm_source=zero.xyz
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-21

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_UcnpYUIMjX3qHWGIxwRVz

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 cryptofeed402-agent-ready-site-audit-62324aa8
```

Example prompt: Can you audit openai.com for AI-agent readiness and tell me its score, grade, and the biggest gaps it needs to fix?

## When to prefer this

Use this endpoint when you need a structured, scored readiness report for whether a public website is properly configured for AI agent discovery and interaction (llms.txt, HTTPS, security headers, etc.). Prefer this over generic HTTP checkers when the specific goal is AI-agent compatibility assessment. Requires x402 USDC micropayment on Base mainnet.

## Known failure modes

- Non-public or non-HTTP/HTTPS URL returns an error
- Host on non-standard ports (not 80/443) rejected
- Unpaid call returns HTTP 402 with x402 payment requirements
- Unreachable or timing-out domain returns audit failure
- Malformed URL input causes validation error

## How this service works

AI-to-AI crypto data. Paid routes use x402 (USDC on Base mainnet eip155:8453, asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913); unpaid calls return 402 with payment requirements. Not financial advice.

## Output

A JSON object containing a numeric score (0-100), a letter grade (A-F), an array of individual checks each with id, name, status (pass/warn/fail), points, weight, evidence, and optional fix suggestion, pass/warn/fail counts, the audited target host/origin, a human-readable summary string, an audit timestamp, and audit version.
