  title: sipi.bot — Spend Firewall for AI Agents Evaluate API
  description: 'sipi.bot sits in front of every transaction an autonomous AI agent attempts and evaluates it against your spend rules — per-transaction caps, daily totals, velocity (runaway-loop protection), merchant allow/block, category limits, time windows, and approval thresholds. It returns APPROVED, BLOCKED, or FLAGGED with a deterministic rules check, before a single dollar moves. Every decision is written to a queryable audit log.


    **The core call an agent makes before spending:** `POST /v1/transactions/evaluate`.


    Auth is optional only for the public evaluation sandbox. Pass `Authorization: Bearer ` for an isolated paid or operator-created workspace. Dashboard and control-plane routes require authentication.'
