Search Contract-Qualified Services

contract_qualified_search

Search Agent402 and the official MPP catalog for paid machine services that both match a capability intent and guarantee buyer-required JSON response paths. Use agent_discoverability_audit when you are measuring one known seller's catalog reach or rank, seller_integrity_audit when you already know the exact seller route to inspect, or payment_offer_preflight when you already have one exact callable GET URL. This search excludes SameDayDesk-owned supply and unresolved routes before audit, uses no credential or wallet, sends no seller POST or target payment, reads no paid response body, and returns only a query digest. Payment challenge and credentials are bound to GET https://agents.samedaydesk.com/commerce/contract-qualified-search, not mcp://. Retry the identical authorized arguments and credential.
