How to read CostRouter pricing

Prices are shown in USD and use the lowest available price multiplier in the selected routing and pricing group. Token models show input and output prices per 1M tokens; per-request models bill per call; dynamic pricing varies with request parameters such as image size, audio duration, cache usage, or pricing tier.

Group price multiplier
Selecting a group shows its available routes and applies its price multiplier to displayed prices.
Model ID
Copy the exact model ID into your SDK or HTTP request body; CostRouter routes the request through one API Key.
Billing type
Compare token-based, per-request, and dynamic pricing before sending production requests.

GPT and Claude API FAQ

Can I access GPT and Claude APIs with one API key?

Yes. One CostRouter API key can access the available GPT, Claude, and other AI models listed in this catalog. Select the required model ID and a compatible endpoint for each request.

How is GPT API and Claude API pricing displayed?

Token-based models show input and output prices per million tokens. Request-based models show a price per request. The final charge depends on the selected model and billing group.

Which API endpoint should I use?

Use one of the compatible endpoints listed for the selected model. The integration documentation provides the CostRouter Base URL and request formats for supported SDKs.
