## Purchase flow

1. GET the catalog. Use only products where commerce.enabled and purchasable are true.
2. Select a valid company or market from catalog.inputs.
3. GET the product endpoint without payment. The server returns HTTP 402 and a base64-encoded x402 v2 PaymentRequired object in PAYMENT-REQUIRED.
4. Apply your wallet's spend policy. If approved, sign the exact USDC requirement and repeat the same request with PAYMENT-SIGNATURE. Sending PAYMENT-SIGNATURE accepts the Terms for that purchase.
5. On successful settlement, the server returns HTTP 200, the intel JSON, an onchain purchase receipt in the body, and PAYMENT-RESPONSE.

No registration, cookies, API key, browser checkout, or subscription is required for these endpoints. Never send wallet private keys to EXVIV.
