Pricing and API questions

How do I calculate the cost of a model request?

Choose the model and route, then check the billing unit and conditions. Text models usually list separate USD rates per million input and output tokens. Cache use, context length and request options may change the rate. Usage records show the settled cost of each request.

Why does the same model have several prices?

A model can have several routing groups with different rates and access conditions. Compare the group, supported protocol and any eligibility requirements together. Promotional rates are subject to their stated conditions; your account may have different access or discounts.

How are image and video requests billed?

Billing depends on the model: per image, per second, per request or by tokens. Resolution, quality, duration, audio and reference inputs can affect the charge. Open the model details and API documentation to check the applicable conditions before sending a request.

Do Castaly generations and API requests use the same balance?

Yes. Castaly at castaly.ai uses your Modelflare account and wallet for image and video generation. Modelflare provides direct API access, API keys and usage records. Review the selected model and request settings in either entry point.

What should I check after a failed or timed-out request?

Check the request or task status, usage record and balance changes. A client timeout does not by itself confirm that an upstream task stopped. If the status and charge do not match, contact support with the request or task ID; never include your API key.

Can every model use the same API format?

No. Supported endpoints and parameters depend on the model and route. Check the model documentation for the exact model ID, endpoint, required inputs and streaming or polling behavior. A model listing does not mean every protocol or parameter is supported.
