## 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 one-engine-url-analysis-pack-tier-8-03654a58 -d '<json body>'
```

Example prompt: Can you run a tier-8 URL analysis on https://example.com/product/123 and tell me what the ONE Engine analysis pack returns about it?

## When to prefer this

Choose this endpoint when you need a deeper, more thorough URL analysis than lower tiers provide and are willing to pay $0.0075 USDC per call via x402 on Base. Prefer this over generic URL parsers when you need tier-calibrated intelligence suitable for autonomous agent pipelines rather than simple URL decomposition.

## Known failure modes

- Invalid or malformed URL input returns an error response
- Payment failure via x402 protocol results in 402 status and no analysis
- Network timeout if the target URL is unreachable during analysis
- Unsupported URL schemes (non-HTTP/HTTPS) may return null or error results
- Rate limiting or quota exhaustion may block repeated rapid calls

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object with a 'tier' field (value 8) and a 'result' field containing tier-8-depth analytical output about the submitted URL, which may include structural metadata, domain signals, or other intelligence extracted at that analysis level.
