API Optimizer
API Optimizer reduces input and output tokens and routes every request to the right model — cutting your API costs significantly, with no quality loss.
You pay per token. We make every one of them count — on both sides of the request.
UsageX lowers input token use while keeping the request focused on the result your application needs.
UsageX reduces generated output tokens while preserving the complete, useful result your application expects.
Each request goes to the cheapest model that can handle it. Expensive models are used only when the task truly requires them.
Point your API traffic at UsageX and pay less per request from day one.
Your API requests pass through the optimizer — no changes to your application logic.
Input and output token use is reduced, while each request goes to the cheapest capable model.
Fewer input tokens, far fewer output tokens, cheaper models for easy work — the savings compound on every single request.
What one optimized request looks like.
→ request "generate a REST endpoint for user profiles" → input tokens reduced → output tokens reduced → model routing cheapest capable model for this task ✓ result same endpoint, a fraction of the token cost
API Optimizer pricing will be announced shortly. In the meantime, Limit Extender is available today.
