Tollbooth: Paid Page Fetch ($0.003/call)

Fetch a page from a tollbooth-registered domain. Costs the publisher's fee_credits from your credit balance (top up at /credits/buy) plus this route's price; 80% of the fee accrues to the publisher. Returns extracted page content. 404 if the domain isn't registered; 409 (not 402) if your credit balance is short.

Paid endpoint: $0.003 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.
