How to pay

Docs: Alchemy for agents (x402 gateway auth). Send a request to x402.alchemy.com without a key, answer the 402 challenge with a signed USDC payment. We decoded the live 402 quote; no payment was made.
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 Alchemy support with it.
