SatGate is an open-source API gateway that enforces hard budgets on AI agent outbound API calls to prevent overspending. It provides per-agent/tool cost caps, attribution, macaroon tokens for delegation, and L402 micropayments. Complements routing gateways by focusing on economic policy enforcement.
Key Points
- 1.Hard budget caps with call rejection
- 2.Per-tool cost attribution and tracking
- 3.Macaroon tokens and L402 micropayments
Impact Analysis
AI agent developers benefit by avoiding surprise costs from loops or prompt injections, enabling safer autonomous deployments. It matters for production use where spending limits are critical. Potential effects include wider adoption of delegated agent architectures without financial risks.
Technical Details
Single Go binary under Apache 2.0, deploys in 60 seconds via GitHub. Uses cryptographic macaroons for scoped credentials and HTTP 402 for per-call payments. MCP-aware for multi-tool chain attribution.
