How this service works
Call when an agent needs published and modified dates extracted from a public page or HTML (SSRF-safe). Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/article-dates first.
Output
Returns the extracted published date and/or last-modified date found in the page's metadata (e.g. Open Graph tags, JSON-LD schema, meta tags, HTTP headers). Dates are returned in a structured format. If dates are not found, the response will indicate their absence.
Example use cases
News article freshness check
“Can you tell me when this news article was originally published and when it was last updated? The URL is https://www.theguardian.com/technology/2024/05/01/ai-regulation-update”
Blog post date extraction from HTML
“I have the raw HTML of a blog post — can you pull out the publication date and any modification date from it?”
Content pipeline date metadata
“I'm processing a batch of article URLs for my content pipeline. Can you extract the published and modified dates from https://techcrunch.com/2024/06/15/startup-funding-rounds/ so I can sort them by recency?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/article-dates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to reliably extract publication or modification dates from a public web page or pre-fetched HTML, especially in an agentic pipeline where content freshness matters. It is SSRF-safe, making it suitable for server-side agents processing arbitrary user-supplied URLs. Prefer the free sandbox endpoint (/v1/sandbox/article-dates) for testing; use this paid endpoint for production workloads requiring reliability.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page has no recognizable date metadata — returns null/empty date fields
- SSRF-blocked URL (private IP ranges, localhost) — rejected for security reasons
- HTML input exceeds 200,000 character limit — request rejected
- URL shorter than 8 characters or longer than 2048 characters — validation error
- Page uses JavaScript-rendered dates only — dates may not be detected from static HTML
