USDCBaseNot statedPay per invoicePay-per-call x402 on /agent/* endpoints, currently $0.0495 USDC per lookup; no account or API key needed. A live unpaid request returned HTTP 402 with a Base USDC requirement. Regular accounts are billed separately.

How to pay

  1. Docs: Hosted MCP Server and x402 Payments (api.builtwith.com/x402-api). Call a /agent/* endpoint without credentials and answer the 402 challenge with a signed USDC payment. Not tested with a live payment.
  2. Choose the coin and the network shown at checkout. Pay only on a network listed above for that coin.
  3. Send the exact amount from a wallet you control, before the payment window expires. Sending on a different network can lose the funds.
  4. Keep the transaction ID until the order is confirmed. If the payment does not show up, contact BuiltWith support with it.
