## 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-9-4c65ab1d -d '<json body>'

Example prompt: Can you run a tier-9 URL analysis on https://example.com and tell me what you find about it?

## When to prefer this

Choose this endpoint when you need a deep, structured analysis of a specific URL and want a low-cost ($0.01 USDC) pay-per-call model on Base via x402. Prefer it over generic scraping tools when you want pre-packaged URL intelligence rather than raw HTML. The tier-9 depth suggests this is among the more thorough analysis levels offered by ONE Engine.

## Known failure modes

- Invalid or malformed URL input returns an error or empty result
- Payment not processed (x402 flow failure) results in 402 response and no analysis
- URL is unreachable or returns non-200 status, leading to incomplete analysis
- Rate limiting or quota exceeded may cause request rejection
- Tier-9 output format may vary; 'Tier-dependent output' suggests schema is not fully documented
