NanoParse reads a web page for AI agents and returns clean Markdown plus Litmus trust signals (source authority, freshness, structural trust, key figures, TL;DR, syndication, paywall/truncation, content type and more), so an agent knows what it just read. $0.005 per parse, paid in USDC on Base via x402 - no account, no API key, no subscription. 10 free parses per month with a signed wallet, or 3 anonymous free tries per network. A page that cannot be read (bot wall, consent wall, paywall, PDF) is reported with a named reason and never charged. Also exposed as a hosted MCP server at https://nanoparse.app/mcp (tools: nanoparse_fetch, nanoparse_status).
