  - before: Read one URL into clean Markdown with Litmus signals (source authority, freshness, structural trust). Price: $0.005 per page actually read, USDC on Base via x402. First 10 free parses per network (subnet). A page we cannot read — bot wall, consent wall, paywall, PDF — is reported with a named reason and never charged. To read a whole site or a list: call this tool once per URL. Build your list first (GET https://<site>/sitemap.xml, or use URLs you already have), then loop. No minimum, no commitment, no balance to spend down: stop whenever you like. If you already know the price and the payTo address, pay on the first call and skip the 402 round trip. Otherwise, when the tool returns a payment_required error, sign the included payment_terms and retry with the payment_signature argument (works in every MCP client; no custom headers needed).
  - after: Read one URL into clean Markdown with Litmus signals (source authority, freshness, structural trust). Price: $0.005 per page actually read, USDC on Base via x402. Free tier: 10 free parses per month with a signed wallet (pass wallet_address + wallet_signature), or 3 anonymous free tries per network.
