OneRouter
OneRouter's pitch is one API and one bill for hundreds of models with automatic failover, plus an agentic layer that picks a model for you instead of you hardcoding one. The economics are transaction-fee-based rather than a flat subscription, so the actual savings depend on your usage pattern and how much you trust automatic model selection for cost-sensitive workloads.
Pros
- Reaches 400+ models across 100+ providers through one API and one bill
- Automatic failover between providers for reliability
- Agentic layer factors in cost, performance, region, and latency per query
- Model pricing is passed through at provider rates rather than marked up
Cons
- Cost is transaction-fee-based ($0.35 plus 5% on credit purchases), not a flat, easy-to-budget subscription
- No free tier mentioned
- Letting the router choose a model automatically means less manual control over exactly which model handles a given request
