## 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 heading-outline-repair-plan-963b8916 -d '<json body>'
```

Example prompt: Check the heading outline structure on https://example.com and give me a repair plan — tell me what's wrong, whether it passes the threshold, and exactly what I need to fix.

## When to prefer this

Choose this endpoint when you need a passive, non-intrusive evaluation of a website's heading outline structure with a concrete repair action plan. It is specifically useful for agent-readiness audits, SEO diagnostics, and content structure validation where no login, form submission, or payload injection should occur. Prefer this over generic SEO tools when you need a structured verdict with evidence provenance and a mode-specific fix recommendation.

## Known failure modes

- Target URL is unreachable or returns non-200 status — endpoint cannot fetch evidence
- Target URL requires authentication — passive check cannot access gated content
- Malformed or non-HTTP(S) URL provided — validation error returned
- Target page has no detectable heading structure — observation notes absence
- Rate limiting or network timeouts on target domain — evidence fetch fails

## How this service works

Heading outline repair plan fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.

## Output

Returns an observation describing the current heading outline state, the evaluation threshold, a pass/fail verdict, the exact public evidence source used, known limitations of the check, and a mode-specific repair action with concrete steps to fix any identified issues.
