Paid agent-facing brief: a fixed-priority decision procedure for choosing among x402 discovery catalogs (Circle, Coinbase Bazaar, PayAI, mpp.dev) by service need type. Includes required inputs, no-pay rule for discovery queries, and pay threshold for selected service. Blunt, non-marketing, for autonomous agents.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
