Output
Returns a JSON object with the fetched URL, page title, optional byline, an extractive summary as an array of sentences, a list of heading objects (text and level), keyword frequency objects, word count, estimated reading time in minutes, and a boolean indicating if the content was truncated. Extraction method is labeled (e.g. 'extractive-tf').

Technical details
Endpoint
GEThttps://grizzly-x402.onrender.com/summarize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, structured extractive summary of a single web page — including headings, keywords, and reading metadata — without needing a full scrape or rendered JavaScript. Ideal for agents that need to digest articles, blog posts, or documentation pages on the fly in a pay-per-call model without a subscription.
Side effects
- Invalid or unreachable URL returns an error or non-200 status field
- Paywalled or login-required pages return little to no content
- Very short pages may yield minimal summary sentences
- Large pages may be truncated (truncated: true) with partial content only
- Payment failure via x402 prevents the call from completing
