## 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-6-914f0618 -d '<json body>'
```

Example prompt: Can you run a tier-6 URL analysis on https://example.com/some-page and tell me what it finds?

## When to prefer this

Choose this endpoint when you need structured, pay-per-call URL analysis without committing to a subscription, especially in autonomous agent workflows running on Base/x402 infrastructure. Prefer it when cost-per-call economics matter and you need a lightweight, no-auth utility for URL inspection at tier-6 depth.

## Known failure modes

- Invalid or malformed URL input returns an error response
- URL unreachable or non-existent may yield empty or degraded result
- Payment failure via x402 prevents processing
- Tier-dependent output may be opaque if tier logic is not documented
- Rate limiting or quota exhaustion on the worker

## 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 6) and a 'result' field containing the tier-dependent analytical output for the submitted URL — such as content classification, metadata signals, or structural insights derived from the URL.
