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.
Example use cases
News freshness verification pipeline
“I need to check when this news article was last modified — can you extract the article:modified_time from https://techcrunch.com/2024/05/01/some-article and tell me the timestamp?”
Content audit from raw HTML
“I've got the raw HTML of a blog post saved locally — can you pull out the article:modified_time Open Graph metadata from it so I know when it was last edited?”
SEO metadata monitoring
“I'm auditing our competitor's site for freshness signals — can you grab the article:modified_time Open Graph value from https://competitor.com/blog/latest-post?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-article-modified?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
