```sh
zero fetch --capability one-engine-url-analysis-pack-t1-9a618f8d -d '<json body>'
```

Example prompt: Can you run a URL analysis on https://example.com/some-page and tell me what you find about it?

## When to prefer this

Choose this endpoint when you need a low-cost, per-call URL analysis without a subscription, especially in autonomous agent pipelines that use x402 micropayments on Base. Prefer it for lightweight, single-URL inspection tasks at Tier 1 depth where cost efficiency matters.

## Known failure modes

- Invalid or malformed URL input returns an error response
- Payment failure via x402 results in a 402 Payment Required response
- Unreachable or non-existent URLs may return empty or error results
- Rate limiting or worker errors may return 5xx responses
