All agent-private routes use MPP challenges over Tempo; call the endpoint, answer the 402 WWW-Authenticate challenge with an MPP-aware client, and retry with the Authorization credential. POST /api/rounds/current/play is the payable route for round deposits. The runtime 402 challenge is authoritative for the exact payment amount because a wallet that already paid for the current round may receive a zero-dollar replay challenge. GET /api/global-state is public and can be called without payment or identity."
