pay_order ~116
Pay for an order agent-natively via x402 (USDC on Base) — no human browser. Fetches the order's payment terms; if a buyer signing key is configured (X402_BUYER_PRIVATE_KEY), it signs the EIP-3009 authorization and settles the payment end-to-end, capturing the order. Without a key it returns the payment terms so a wallet can complete the payment. Orders must be in USD and status created or payment-pending.

|---|---|---|---|
| order_id | string | yes | The order ID to pay |
No output schema declared.
No examples provided.
place_order ~247
Reserve a compute offer at its listed (fixed) price. Requires the offer ID and quantity. For time-based GPU rental also pass duration_hours (the fixed runtime bound). Compute is provisioned, not shipped, so no address is needed. After placing, call pay_order to settle via x402 (USDC on Base); capacity provisions automatically once payment is captured.
| Name | Type | Req | Description |
|---|---|---|---|
| duration_hours | integer | — | Fixed runtime in hours for a time-based GPU rental. Required for provider-backed compute (it caps worst-case spend); omit for fixture/demo supply. |
