Yes. The entire open-source core is MIT-licensed and free to self-host forever — full policy engine, dashboard, audit trail, MCP tool, HTTP API, and CLI. The hosted plans add managed infrastructure, persistent log retention, and support.
One call to the /v1/transactions/evaluate endpoint — your agent asking "should I spend $X at merchant Y?" Each plan includes unlimited evaluations. There is no per-call fee, no metering, no overage charge.
If sipi.bot returns "approve" for a transaction that violated one of your active rules, that month's subscription is refunded. The guarantee covers rule-evaluation engine errors, not losses from rules you didn't configure or from acting against a block/flag decision.
Stripe returns you to a private sipi.bot activation page where your API key is displayed with a copy button, a first protected transaction, and framework-specific integration links.
Email sales@sipiteno.com from the billing email. We will confirm the effective date before the next renewal; there is no long-term contract.
Every block includes the exact rule and reason. Adjust or disable that rule in the dashboard, then retry the transaction. A blocked evaluation never moves money itself.
The policy check is deterministic local code with no model inference. End-to-end hosted latency depends on your network path and current service load, so measure it from your deployment region before putting it on a critical payment path.
Why trust sipi.bot with your agent's spending
The rules engine is pure logic — no ML guessing. If a rule says block at $500, every $501 transaction is blocked, every time, with a reason you can audit.
The exact code running the hosted service is on GitHub (MIT). You can read every rule-evaluation path and self-host the same engine.
Every evaluation records its decision, rule, reason, amount, merchant, agent identity, and timestamp in SQLite for review.
The rules engine is deterministic local code with no model call. Hosted latency still includes the network path between your agent and sipi.bot.
