Looking for an alternative to your current tool? sipi.bot is a pre-spend firewall designed specifically for autonomous AI agents — with velocity limits that kill retry loops, merchant allowlists that block unknown vendors, and a human approval queue. Here's how it compares to the tools you might be using today.
Native spend controls on top of any LLM proxy. Pre-spend enforcement, not reactive budget caps.
Spend enforcement (not just observability). Velocity limits, merchant allowlists, human approval.
Multi-provider, per-agent, pre-spend — not just a monthly OpenAI cap.
Stop runaway spend before it happens, not just trace it afterward.
Payment guardrails in addition to prompt-level safety.
Spend firewall alongside prompt validation.
Policy-as-code for agent spend, not just infrastructure access.
Agent payment protocol + pre-spend firewall — the compliance layer in front of the wallet.
Stripe Radar is the right tool for stolen cards and chargebacks. It's the wrong tool for 'your agent bought from an unknown vendor 40 times.' Here's the alternative layer.
OpenRouter is a routing layer — one API to many models. It optimizes access, not spend. Here's the layer that enforces the budget.
LangSmith is the observability layer for LangChain and LangGraph. It shows you what agents did — after they did it. The alternative layer stops the money.
