# AI Utility Farm URL Evidence Analyzer

> AI Utility Farm URL Evidence Analyzer is a paid API for AI agents from ai-utility-farm.brycedees1.chatgpt.site, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Fetches and analyzes a public URL, returning page metadata including HTTP status, content hash, title, and capture timestamp as a structured evidence report.

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 ai-utility-farm-url-evidence-analyzer-97a8fd3a -d '<json body>'
```

Example prompt: Can you fetch https://example.com and give me a snapshot of its current content — the page title, HTTP status, whether it redirected, and a content hash so I can verify it later?

## When to prefer this

Choose this endpoint when you need a lightweight, paid-per-call ($0.01 USDC) web snapshot with cryptographic content fingerprinting (SHA256), HTTP-level metadata, and a structured evidence record — especially useful for auditing, change detection baseline capture, or verifying URL liveness at a known timestamp. Prefer it over generic scrapers when you need a verifiable, timestamped evidence artifact rather than full page HTML extraction.

## Known failure modes

- URL is unreachable or times out — endpoint may return an error or partial result
- URL uses a non-HTTP/HTTPS scheme and fails schema validation
- Private or firewall-protected URLs cannot be fetched from the server's network
- Payment not included or invalid — returns HTTP 402 requiring x402 Base USDC payment
- Malformed URL input fails URI format validation before request is made

## How this service works

## Output

A JSON object conforming to the url-evidence-v1 report type, containing the requested URL, the final URL after any redirects, fetch timestamp, HTTP status code, elapsed response time in milliseconds, whether a redirect occurred, the page title, SHA256 content hash, and number of bytes captured.
