Tollbooth: Register Your Site ($0.050/call)

Pay-per-crawl for publishers: register a domain + payout wallet + per-fetch fee (1-100 credits). Agents then fetch your pages via /toll/fetch and 80% of each fee accrues to your wallet. Registration is a paid call (spam gate); re-register to update.

Paid endpoint: $0.050 per call via the x402 protocol (USDC on Base). An unpaid request returns 402 with payment requirements in the PAYMENT-REQUIRED response header; attach payment and retry.
