Example use cases

Competitive page monitoring snapshot
“Grab the content of https://www.openai.com/pricing as clean markdown so I can compare it to last week's snapshot.”

Technical details
Endpoint
GEThttps://ipv4.fr/x402/v1/markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to convert a single public web page into clean, readable Markdown for downstream processing, indexing, or LLM context injection. It is especially well-suited when you also want an AI-generated summary without building your own summarization pipeline. Prefer it over raw HTML fetching when readability-extracted text is needed, or over generic scraping tools when you need structured Markdown output with metadata like title, language, and word count.
Side effects
- URL is not publicly accessible or returns a non-200 status — endpoint may error or return empty content
- Page exceeds 5 MB limit — content will be truncated (truncated: true in response)
- URL points to a binary file (PDF, image) rather than HTML/text — extraction quality may be poor
- AI summary requested (summary=1) but the page content is too short or ambiguous — summary may be low quality
- Network timeout or DNS resolution failure for the target URL — results in an error response
- Rate limiting or payment failure at $0.005/call (or $0.01 with summary) via x402 protocol
