  • Endpoint POST /purchase returned 400 (expected 402)

Paid Operations (1)

POST /purchase dynamic
Purchase wine. Requires identity verification via AgentScore and MPP payment.

Identity paths (choose one): (1) X-Wallet-Address when paying from a crypto wallet on Tempo MPP or x402 — the wallet you claim MUST sign the payment; same-operator linked wallets are fungible. (2) X-Operator-Token for any payment rail (Tempo, x402, Stripe SPT, card) — reusable across AgentScore merchants until expiry. Neither header → 403 with verify_url and session. See /llms.txt for the full flow.
