https://sipi.bot The Spend Firewall for AI Agents en Mon, 27 Jul 2026 13:35:02 GMT Hermes WebSub Feed Generator 60 https://sipi.bot https://sipi.bot sipi.bot is a spend firewall for autonomous AI agents: one API call returns APPROVED, BLOCKED, or FLAGGED against your caps, velocity, and merchant rules before an agent spends. Not a SIP/VoIP telephony bot. sipi.bot Tue, 07 Jul 2026 21:00:00 GMT https://sipi.bot/learn/spend-firewall-guide https://sipi.bot/learn/spend-firewall-guide The complete guide to AI agent spend control: what a spend firewall is, the 6 rule types every autonomous agent needs, how it differs from LLM budgets and observability tools, and how to deploy one in 5 lines of code.

A practical guide to retry loops, unattended sessions, and the pre-spend rules that bound them. sipi.bot Fri, 17 Jul 2026 21:00:00 GMT https://sipi.bot/how-to/prevent-runaway-ai-costs https://sipi.bot/how-to/prevent-runaway-ai-costs Runaway AI agent costs happen when a retry loop or unattended session spends before you notice. The fix is a pre-spend firewall: per-transaction caps, velocity limits, and merchant allowlists that block the spend before it fires.
