Bring your bill
No integration, no proof of concept, no estimate to take on faith. The invoice your provider already sends - or its usage export - is enough to price the same traffic through the router, line by line, model by model, and to leave with the number you would have saved.
On this deployment, for reference
100% less
Traffic routed here has cost $0.32 against $392.87 had every request gone to the priciest model. Your bill will differ; the analysis says by how much.
Bring your bill
No pilot, no integration, no estimate to take on faith. The invoice your provider already sends - or its usage export - is enough to price the same traffic through the router, line by line, model by model.
The PDF your provider sends every month, or the usage export from its console - a date, a model, token counts and the amount charged.
The platform reads the vendor, the billing period and every line that names a model, and aggregates by day, provider and model. Addresses, tax ids and every other word are ignored and never stored.
What the bill says next to what the router's recommended target would have charged for requests of the same shape. Download the report as CSV, a workbook or a PDF.
Free plan, no card. The analysis lives in your workspace and can be deleted at any time; the figures are estimates and the report says so. For reference, traffic routed on this deployment has cost 100% less than sending every request to the priciest model.
