## 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 date-extraction-from-web-page-f77a240e
```

Example prompt: Can you pull all the dates from this article page — I want to know when it was published, when it was last modified, and the best guess at the actual publication date: https://example.com/article/some-news-story

## When to prefer this

Choose this endpoint when you need to determine when a web page was published or last modified, especially when combining signals from meta tags, schema.org, and body text gives a more reliable answer than any single source. Ideal for content freshness checks, fact-checking pipelines, research timelines, and indexing workflows where publication date accuracy matters. Prefer this over generic scrapers when you specifically need structured temporal metadata rather than full page content.

## Known failure modes

- Page has no date signals in meta tags, schema.org, or body text — returns empty or null date fields
- URL is unreachable or returns a non-200 HTTP status — extraction fails with error
- Page requires JavaScript rendering and dates are only in dynamically loaded content — may miss dates
- Ambiguous date formats lead to incorrect parsing or wrong best-guess publication date
- Paywalled or bot-blocked pages may not return full content for date scanning

## How this service works

Date extraction from a page: the published and modified dates from meta tags and schema.org, plus dates found in the text (ISO, US and long forms), the earliest and latest, and a best guess at the publication date. Content freshness and timeline building. $0.01 per page.

## Output

Returns published and modified dates extracted from meta tags and schema.org markup, a list of all dates found in the page body (ISO, US, and long-form formats), the earliest and latest dates found, and a best-guess publication date inferred from all available signals.
