Extract Web Page as Structured JSON

extract

Fetch a public HTTP(S) page and return compact extraction signals for programmatic inspection: title, meta description, Open Graph/Twitter metadata, JSON-LD, headings, links, text excerpt, and AI-readiness flags. Use read instead when you need the page body as LLM-ready Markdown rather than metadata or a link inventory. Does not execute JavaScript; follows redirects and applies SSRF, timeout, and response-size guards. Payment challenge and credentials are bound to GET https://agents.samedaydesk.com/extract, not mcp://. Retry the identical authorized arguments and credential.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`url`	Yes	Public HTTP(S) URL. Choose extract for metadata, JSON-LD, headings, links, and a bounded text excerpt; use read for longer bounded Markdown. Content is fetched without JavaScript rendering. Check status/sourceOk/error/capture; ok means a typed extract record, not source completeness.
`textExcerptLimitChars`	No	Optional excerpt budget. Default 1200. Maximum 40000. Rejected before fetch. Does not purchase /read or change the price.
