Page Summarizer API

GET /api/summarize $0.015 per call USDC on Base · x402

Quick extractive summary of any web page: fetch the URL, extract the main article, and return the key sentences (TextRank) instead of the full text. For agents that want the gist of a page, not a full scrape. No AI — fast and deterministic.

Parameters

NameInDescription
urlqueryrequiredPublic http(s) URL of the page to summarize
sentencesqueryHow many key sentences to return (1-10, default 3)

Example request

# first call returns 402 + payment requirements; an x402 client pays and retries automatically

MCP tool: get_summarize — via npx -y webbersites-x402-mcp (local, key stays on your machine) or the remote endpoint https://api.webbersites.com/mcp.

How payment works

There is no signup and no API key. Call the endpoint; it replies 402 Payment Required with machine-readable payment requirements. Your client signs a USDC transfer authorization (EIP-3009, gasless) and retries with the X-PAYMENT header — @x402/fetch does this automatically. See the overview for a working snippet.
