Spend Firewall for AI Support Agents
AI customer support agents are the new frontline — handling refunds, applying credits, upgrading tiers, and issuing compensation. One poorly-prompted agent can issue $10,000 in refunds before anyone notices. sipi.bot adds a transaction firewall: every refund, credit, or upgrade goes through rules before it executes.
Support agent controls
- Refund limit: Max refund per customer, per agent, per day
- Credit cap: No individual credit over $100 without human approval
- Escalation rules: Transactions over threshold → FLAGGED for human review
- Customer velocity: Multiple refunds from same customer in 24h → BLOCKED
- Agent-specific limits: Different rules for different agent roles and trust levels
Common spend patterns for AI Support Agents
AI Support Agents run agents that can move money in the course of their work. The exact pattern varies, but the failure modes repeat: an agent loops on a paid API call, a tool call hits the wrong merchant, a multi-step workflow accumulates charges faster than anyone expected, or a prompt injection tricks the agent into a transaction it should never have made.
A runaway agent's cost is bounded only by the limits you set before it spends. The pattern is not rare and it is not cheap.
How sipi.bot fits your workflow
sipi.bot is a spend firewall for autonomous AI agents. It sits between your agent code and your payment methods, evaluating every transaction against your rules in under 5 milliseconds and returning one of three structured decisions: approve, block, or flag. Per-transaction limits, daily ceilings, velocity caps, merchant allowlists, and human-in-the-loop escalation are all enforced before a dollar moves. Pricing starts at $99 per month.
For AI Support Agents, the value is enforcement, not just observability. Dashboards tell you what happened after the money moved. A spend firewall stops the transaction before it moves. The difference, on a runaway loop, is the difference between a $2 anomaly and a $2,000 incident.
A typical deployment
- List the transactions your agents actually initiate — paid API calls, provisioning, purchases, refunds.
- Set a per-transaction limit that covers legitimate use but flags anything unusual. For most AI Support Agents workflows, $1 to $5 per transaction is enough.
- Set a daily ceiling per agent ($10-$50 for development, higher for production).
- Add a velocity cap (transactions per minute) to catch loops. Ten per minute is a reasonable starting point.
- Configure a merchant allowlist so the agent can only transact with vendors you have approved.
- Turn on alerts and run a postmortem on every flagged transaction.
Why AI Support Agents choose sipi.bot
The alternative is building this yourself: a policy engine, a decision API, an audit log, alerting, and a review workflow. That is months of engineering for a problem that is not your core product. At $99/mo, sipi.bot is cheaper than a single incident and deploys in an afternoon.
