What Saturn Does
- Routes requests to 15+ upstream providers (OpenAI, Anthropic, Serper, E2B, and more)
- Enforces budgets with per-agent caps and daily limits
- Processes payments via card (USD) or Lightning (sats)
- Logs everything with full audit trail and cost attribution
Runtime Enforcement vs Dashboards
Dashboards show you what happened. Saturn prevents what shouldn’t happen.
Saturn operates at the execution boundary. Every capability call passes through policy checks before reaching any upstream provider. Over-budget calls are rejected—not logged, not alerted, rejected.
Architecture
- Authenticated via agent API key
- Checked against policy (caps, allowed capabilities)
- Quoted against current credit balance
- Executed only if all checks pass
- Settled atomically with receipt issued
