How this service works
Confirm a checkout intent. The first call returns 402 with an x402 payment challenge for the purchase total plus the Stripe crypto surcharge. Retry with the PAYMENT-SIGNATURE header to complete the confirmation. This is step 1 of 3 for purchasing a product: (1) POST /v1/checkout-intents with productUrl → returns intent id ($0.02 USDC). (2) GET /v1/checkout-intents?id={id} (free, wallet-scoped — requires X-Wallet-Address matching the buyer wallet) → poll until state="awaiting_confirmation" and review priced offer. (3) POST /v1/checkout-intents/confirm → finalize purchase (dynamic cost = order total + $0.03 API fee + ~1.5% Stripe surcharge). Wallet-native checkout for 15k+ merchants — Shopify, Amazon, Best Buy, and others.
Output
Returns a JSON object with the checkout intent id and updated state (e.g. 'confirmed' or intermediate state). First call returns HTTP 402 with an x402 payment challenge encoding the order total plus $0.03 API fee and ~1.5% Stripe surcharge; the agent must sign and retry with a PAYMENT-SIGNATURE header to get the final confirmed response.
Example use cases
Example prompt

Technical details
Endpoint
POSThttps://x402.rye.com/v1/checkout-intents/confirm?utm_source=zero.xyzWhen to prefer
Use this endpoint as step 3 of the Rye x402 three-step checkout flow, after creating an intent (POST /v1/checkout-intents) and polling until state='awaiting_confirmation' (GET /v1/checkout-intents). Choose this over generic payment APIs when your agent needs wallet-native USDC checkout across 15k+ merchants including Shopify, Amazon, and Best Buy, with x402 protocol payment gating.
Side effects
- 402 on first call — expected; agent must extract x402 challenge and retry with PAYMENT-SIGNATURE header
- Invalid or missing PAYMENT-SIGNATURE header — payment rejected, intent not confirmed
- Intent not in 'awaiting_confirmation' state — must poll GET /v1/checkout-intents?id={id} first
- Wallet address mismatch — intent was scoped to a different buyer wallet
- Intent expired or already confirmed — stale id returns error
- Insufficient USDC balance to cover order total plus fees
