FAQ

Claude Sonnet 5 API questions

What model ID should I use for the Claude Sonnet 5 API?+

Use claude-sonnet-5 in the model field. This is the stable PixMind route identifier shown in the playground request JSON.

Which endpoint does the Claude Sonnet 5 API use?+

Send POST requests to /v1/chat/completions. Keep your API key on your server and pass it as a Bearer token.

Is the playground using a real API request?+

Yes. When you click Run model, PixMind forwards the displayed payload with the API key you entered. A successful request may create a paid task.

Does PixMind save the API key entered here?+

No. The playground keeps the key only in component memory and sends it for the current request; it is not written to browser storage.

Is API pricing the same as PixMind Studio pricing?+

No. API usage resolves through the apiPlatform pricing role and a separate pay-as-you-go ledger. Studio pricing includes the creation interface and product workflow services.

Why can the final price differ from the starting price?+

The entry price reflects the configuration displayed on this page. Resolution, duration, quality, audio, references, and output count can affect the final task price.

How do I receive a finished image or video?+

Generation routes can return an asynchronous task. Save its ID and query the task endpoint until the status is succeeded, failed, or cancelled.

Can I use the same integration for other PixMind models?+

Yes. Models in the same workload family share the generation contract, so switching usually means changing the model ID and supported parameters.
