Technical details
Endpoint
GEThttps://api.firstmention.uk/s/webmd/extract?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to read, extract, or convert the content of a specific known public URL into structured, agent-readable Markdown. It is ideal when you already have the URL and want clean text with headings, link counts, and robots metadata — rather than discovering URLs (use websearch for that) or auditing page quality (use pageaudit). At $0.01 USDC per call via x402 micropayment, it is cost-effective for single-page reads or small batches.
Side effects
- URL is not publicly accessible or returns a non-200 status — ok: false with HTTP status code
- URL points to a non-HTML resource (PDF, binary) that cannot be parsed to markdown
- Page blocks bots via robots.txt — robots.allowed: false returned
- Invalid or malformed URL input — validation error returned
- Timeout if the target server is slow to respond
- Truncated response if page content is very large — truncated: true flag set
