Each operation describes its service.
Output
Returns a JSON object containing the page URL, byte size, HTTP status, title, description, format, and depending on the requested mode: main_text (plain text), markdown, outline (headings with levels), links (URL+anchor text), images, tables, or jsonld. Includes character count and a truncated flag if the limit was reached.
Example use cases
Extract article text for summarization
“Grab the main text from this news article at https://www.bbc.com/news/world-us-canada-12345 and return it as plain text — limit it to 5000 characters so I can summarize it.”
Scrape all links from a webpage
“Pull all the links from https://docs.example.com/api-reference and only give me links that stay on the same domain — I want to map out the documentation structure.”
Extract structured JSON-LD data
“Read https://www.recipe-site.com/chocolate-cake and return the JSON-LD structured data so I can see what schema.org markup they've embedded on the page.”
Technical details
Endpoint
POSThttps://api.firstmention.uk/s/webread/read?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract structured content from any public webpage in a specific format (text, markdown, links, tables, JSON-LD, etc.) with precise character limits, and you want to pay per-call via USDC x402 without a subscription. Prefer it over general web search when you already have the URL and need the actual page content rather than a search result snippet.
Side effects
- URL is not publicly accessible (private, behind auth wall) — returns non-200 status
- URL is malformed or unreachable — connection error
- Page returns non-HTML content (e.g. PDF, binary) — may return empty or partial main_text
- Character limit out of range (must be 200–60000) — validation error
- Rate limit or payment failure via x402 — 402 Payment Required response
