The AI gateway built for agents: failover before the first token, smart routing, and cache hits at 30% off. Prepaid credits, no seat fees.
Septor Labs is the AI gateway built for agents.
One API key works with OpenAI-style and Anthropic-style clients. Every call is routed to a healthy provider by priority, weight, least-connections, or latency, and a circuit breaker pulls a failing provider out of rotation. If a provider fails before the first token, the call fails over automatically, so your agent keeps going instead of losing the turn.
Turn on semantic caching and repeat prompts cost 30% less. Set the model to auto and the router picks for you, or pin a model when you want control.
Pricing is built for agents that run all day. Credits are prepaid, every key gets its own budget and optional IP allow-list, and there are no seat fees. Range-priced models are never billed above the published ceiling, and on most of them the cheapest rate is 30% or more below it. New accounts start with $1 of free credit.
