## 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 article-modified-time-extractor-5e665c50 -d '<json body>'
```

Example prompt: Can you pull the article:modified_time Open Graph tag from this page — https://example.com/blog/my-post — and tell me when the article was last updated?

## When to prefer this

Use this endpoint when you need specifically the article:modified_time Open Graph metadata from a page and want a lightweight, paid, SSRF-safe extraction rather than fetching and parsing HTML yourself. Prefer the free sandbox endpoint (/v1/sandbox/profile-article-modified) for development and testing before using this paid version. Best suited for pipelines that need structured modification timestamps from articles at scale without building a scraping layer.

## Known failure modes

- URL is unreachable or returns non-200 status — extraction fails with an error
- Page does not contain an article:modified_time Open Graph tag — returns empty or null result
- HTML input exceeds 200,000 character limit — request rejected
- URL shorter than 8 characters or malformed — validation error
- SSRF-blocked private/internal URL submitted — request blocked
- Both url and html fields omitted — missing required input error

## How this service works

Call when an agent needs article:modified_time extracted from a public page or HTML (SSRF-safe). Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/profile-article-modified first.

## Output

Returns the value of the article:modified_time Open Graph meta tag found in the page or HTML, typically an ISO 8601 datetime string indicating when the article content was last modified. Returns null or an empty result if the tag is not present.
