How to pay

Docs: Machine Payments > Tavily x402. Call POST /search without a key, answer the 402 challenge with a signed USDC transfer authorization on Base. Not tested with a live payment.
Choose the coin and the network shown at checkout. Pay only on a network listed above for that coin.
Send the exact amount from a wallet you control, before the payment window expires. Sending on a different network can lose the funds.
Keep the transaction ID until the order is confirmed. If the payment does not show up, contact Tavily support with it.
