summary: >-
  Agent Bench publishes budget-style limits rather than a requests-per-second ceiling: a shared anonymous
  search budget per day and per month, and a daily cap on guest purchases shared by all guests, plus a
  per-purchase spending ceiling and a mandate lifetime for guests. No rate-limit response headers are
  documented or were observed; the runtime signal is unusual and better — GET /health publishes the live
  counters, and an exhausted budget is written to the public ledger as a request.refused entry with reason
  search_budget_exhausted. The HTTP status or JSON-RPC shape a caller receives on exhaustion is not documented
  and was not exercised.
