CostRouterUnified access. Shared controls.
One API key
One balance
Unified usage records
Choose your models. Manage access and costs together.
More model choice. Less integration overhead.
Managing another model provider shouldn’t mean another set of keys, balances and bills. CostRouter brings integrated models into one platform, preserving choice while reducing maintenance.
Choose models for the task
Compare capabilities and published rates, then use different models through the same platform.
Bring spending together
Fund one account, pay for actual usage and review usage and billing in one place.
Make cost a decision. Not a discovery.
From model selection to requests and reconciliation, make cost management part of everyday operations.
Understand the price
Compare model rates and estimate input and output costs before choosing a model for each task.
Model pricing / Cost estimatesDefine the boundaries
Create API keys for different uses. Set quotas and permitted models to put clear limits on consumption.
Key quotas / Model restrictionsAccount for usage
Review models, token usage, charges and request status to identify spending and reconcile your bills.
Usage logs / Billing recordsFrom a first application to enterprise operations.
Developers & independent projects
Connect coding tools, personal applications and product prototypes. Start with one account and pay for what you use.
AI products & SaaS teams
Choose models for assistants, agents and product features, with centralized access and visibility into ongoing costs.
Enterprise engineering & business teams
Unify model access for internal applications, separate API keys by purpose and agree on capacity, pricing and support for your scale.
Cost control, built on trust.
Read our service & data commitmentsYour model stays your model
We never silently substitute your requested model. Failover uses only compatible routes serving that same model.
Traceable spending
Published model rates and usage records for billing and reconciliation keep costs accountable.
Clear data boundaries
CostRouter does not retain prompts or model outputs, or train on customer content. Upstream data policies require separate assessment.
