How this service works
Call when an agent needs Mozilla Readability article markdown from a public URL, plus title, byline, excerpt, and final_url. SSRF-safe. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/readability first.
Output
Returns structured JSON containing the article body as Markdown text, the article title, byline (author), a short excerpt, and the final resolved URL after any redirects — all extracted using Mozilla Readability.
Example use cases
Research article summarization
“Grab the full article from https://www.bbc.com/news/technology-12345678 and pull out the clean text as markdown so I can summarize it.”
Newsletter content extraction
“I need the readable body, title, and byline from this Medium post — https://medium.com/@author/some-post-slug — can you extract it cleanly?”
Fact-checking a source URL
“Pull the main article content from https://reuters.com/article/some-story and tell me the title, author, and text so I can verify the claims.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/readability?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need clean, reader-mode article text from a public URL in Markdown format, especially when you also need structured metadata like title, byline, and excerpt. It is SSRF-safe making it suitable for untrusted user-supplied URLs. Prefer the free sandbox endpoint (/v1/sandbox/readability) for testing before paying. Prefer this over generic scraping tools when the goal is article content rather than raw HTML or structured data extraction.
Side effects
- URL is behind a paywall or login wall — returns empty or minimal content
- URL resolves to a non-article page (homepage, search results) — Readability may return little or no content
- SSRF-protected: private/internal IP ranges and localhost URLs are rejected
- URL is malformed or unreachable — returns an error
- Dynamic JavaScript-rendered content may not be fully captured
- URL exceeds 2048 character limit — rejected by schema validation
