Fetch any URL and return its article content with the clutter stripped — nav, ads, sidebars, footers, scripts, styles, comments removed via heuristic extraction (<article> / <main> / role=main / densest block). Choose the output with `format`: markdown (default), text, both (JSON envelope), html (a self-contained readable reader-view page, raw text/html), or pdf (a clean typeset reading document, raw application/pdf). html/pdf are built from the same cleaned content, so they carry no live page, no third-party assets, no trackers. SSRF-guarded, 512KB body cap, 8s timeout, 5 redirects max. JSON formats return { url, finalUrl, title, markdown?, text?, wordCount, sourceBytes }. This uses a raw HTTP fetch (no JavaScript) — for client-rendered / SPA pages whose content only appears after JS runs, use /api/url/render (same formats, headless-rendered). For a pixel-perfect image of the live page use /api/ai/screenshot; to enumerate a page or sitemap into its links use /api/url/map.
/api/url/cleanPAYMENT-SIGNATURE.The clean API is a pay-per-call url endpoint built for AI agents and autonomous software. Fetch any URL and return its article content with the clutter stripped — nav, ads, sidebars, footers, scripts, styles, comments removed via heuristic extraction (<article> / <main> / role=main / densest block).
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in clean data source for an agent tool-use loop, an MCP host, or a backend that needs url data on demand without onboarding to yet another vendor portal.
