You pay the call price for

An answer, including a definitive “not found” or an empty result.

Invalid input and source failures are not charged.

How x402 payment works

Your client sends the request. The API answers 402 Payment Required with the price and where to pay.
The client pays from its own wallet: USDC on Base or Solana over x402, or over MPP on Tempo. No account, sign-up or API key.
The client retries with the payment attached and gets the JSON answer in the same call. You are only charged for answers.

The AgentCash CLI in the example does all three steps for you and pays from your AgentCash wallet. Any x402 or MPP client works the same way.
