How to pay

  1. Docs: Build with AI > x402 payments. Call an endpoint without an API key, answer the 402 challenge with a signed USDC transfer (or use zerion-cli with --x402). 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 Zerion API support with it.
