Pay per crawl, live▌
This site charges AI agents $0.01 per page using the
x402 protocol on a Cloudflare Worker.
Humans get an explanation. Agents get an invoice.
The priced article
/research/agentic-seo/
Returns HTTP 402 Payment Required until the caller pays $0.01 in USDC on Base Sepolia (testnet).
The ledger
/earnings/
Running total, crawl count and the last five paid crawls.
How the handshake works
1. GET /research/agentic-seo/ 2. 402 Payment Required + PAYMENT-REQUIRED header (price, token, network, pay-to) 3. Agent signs a USDC authorisation and retries with PAYMENT-SIGNATURE 4. Facilitator verifies and settles on chain 5. 200 OK + article + PAYMENT-RESPONSE header (settlement confirmation)
