## 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 deadlinecheck-78741c9d -d '<json body>'
```

Example prompt: Can you check this page and pull out any deadlines or closing dates mentioned on it? https://example.com/opportunity

## When to prefer this

Choose this endpoint when you need structured, machine-readable deadline data extracted automatically from a public webpage without manual parsing. It is ideal for agents monitoring grant portals, job boards, RFP pages, or academic admissions sites where deadlines are embedded in prose. Prefer it over general-purpose web scrapers when you specifically need deadline/date extraction with confidence scoring and timezone awareness.

## Known failure modes

- URL is not publicly accessible (returns error or empty result)
- Page content is behind a login wall and deadlines cannot be read
- No deadlines found on the page (deadlines_found: false, empty deadlines array)
- Ambiguous or relative date references (e.g. 'next Monday') may lower confidence score
- Page uses non-standard date formats that reduce extraction accuracy
- Network timeout or unreachable URL
