Payment surface discovery for clients before attempting a paid call. 1. `GET /payment/health` - rail challenge and configuration status. 2. `GET /payment/quote?endpoint=/path` - per-endpoint price across candidate rails. 3. For generic paid agents, fetch a safe-method 402 challenge, then POST with a verified rail credential. Unpaid executable POST remains Delegation-gated. `GET /payment/discovery` aggregates rail status and quotes. `GET /payment/badge` returns a compact status badge payload. Discovery is cached and does not represent settlement, adoption, or revenue evidence.
