## 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 seo-title-present-audit-0de9a2a6 -d '<json body>'
```

Example prompt: Can you do a passive SEO audit of https://example.com and check whether the page has an HTML title tag present — I want to know the verdict, what evidence it found, and what action I should take?

## When to prefer this

Choose this endpoint when you need a lightweight, passive, read-only check specifically confirming HTML title tag presence on a public page — ideal for pre-publish checklists, post-deploy verification, or regression monitoring after site changes. Prefer it over full-crawl SEO suites when you only need the title criterion evaluated quickly and cheaply without side effects or authentication.

## Known failure modes

- Target URL is unreachable or returns a non-200 status, resulting in an inability to fetch evidence
- Malformed or non-public URL rejected at input validation
- Page uses heavy JavaScript rendering that prevents static title detection, noted as a limitation
- Rate limiting or network timeouts on the target server causing incomplete audit
- Domain normalization fails for unusual TLDs or non-standard URLs

## How this service works

Title present audit 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 a structured audit result including: the observation (what was found on the page), the threshold being evaluated against, a pass/fail verdict, the exact evidence source URL, any limitations of the passive check, and a mode-specific recommended action — all without performing any login, form submission, or intrusive testing.
