Agent Search
Cross-retailer product search for agents, paid per call via MPP.

Agent Search
GET /agent/search is the agent-native counterpart to Cross-Retailer Search. It returns a single ranked list of buyable products across every supported retailer, and each result’s url can be passed straight to Create MPP Order — no opaque sku id, the URL is the contract.
No Zinc account is required. Like the other /agent/* data endpoints, this call is paid per request via the Machine Payments Protocol (MPP): if no valid payment credential is provided, the API returns 402 Payment Required with a WWW-Authenticate challenge for each configured payment method.

402 Payment Required
If no valid payment credential is provided, the API returns402 Payment Required with one WWW-Authenticate header per payable method (per RFC 9110 §11.6.1). Your MPP client uses these to complete payment and resubmit the request. See the MPP guide for a full walkthrough.
