## 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 schema-nsgoods-org-extractability-scorer-32f79e89
```

Example prompt: Can you check how extractable this page is for AI answer engines — score it and tell me what's broken and how to fix it: https://example.com/blog/my-article

## When to prefer this

Use this endpoint when you need a structured, scored audit of a specific URL's AI/answer-engine extractability — especially when you want actionable fixes alongside the score. Prefer this over generic SEO tools when the goal is optimizing for LLM citation and answer-engine inclusion rather than traditional search ranking.

## Known failure modes

- Non-public or private URLs may return an error or zero score
- Invalid or malformed URLs return a validation error
- Paywalled or access-restricted pages may be un-fetchable, resulting in incomplete scoring
- Timeout if the target URL is slow to respond
- Payment not provided or insufficient USDC balance returns HTTP 402
