How this service works
One public page as markdown. The free floor does not fetch the web, and /api/check does not return the page
Output
Returns the full content of the requested public web page converted to markdown format, including headings, paragraphs, links, and other text elements from the page body.
Example use cases
Research article content extraction
“Go grab the content of this blog post for me: https://news.ycombinator.com/item?id=12345 — I want to read through what it says in plain text.”
Competitor pricing page monitoring
“Fetch the page at https://competitorsite.com/pricing and pull back the text so I can see what their current plans and prices look like.”
Documentation ingestion for AI agent
“Retrieve the content of https://docs.somelib.io/getting-started as markdown — I want to feed it into my agent so it knows how to use the library.”
Technical details
Endpoint
GEThttps://altspider.ai/api/fetch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to retrieve the readable text content of a single public web page as markdown, especially in an agentic workflow where you want clean, structured text rather than raw HTML. It is well-suited for one-off page fetches where you know the exact URL. Prefer this over general-purpose crawlers when you only need a single page and want markdown output directly.
Side effects
- URL is not publicly accessible or requires authentication — page content not returned
- The free tier does not actually fetch the web; paid call required to get real content
- Malformed or missing URL query parameter causes request failure
- Non-GET/HEAD/DELETE HTTP methods are not supported and will be rejected
- Page may be behind JavaScript rendering and content may be incomplete
- Rate limiting or payment failure via x402 protocol blocks the request
