FAQ

Kling 4.0 API questions

Qual ID de modelo e endpoint de API devo usar?+

Envie kling-v4 para POST /api-platform/v1/generations. Pesquise o PixMind taskId retornado em GET /api-platform/v1/tasks/{taskId}.

Como escolho o modo de referência, edição ou extensão?+

Defina omni_reference_task_type para referenciar, editar ou estender. Editar e estender requerem uma entrada de vídeo; extensão não aceita aspect_ratio ou audio_setting.

O que significa preço de entrada 720p?+

É a taxa de US$ 0,105 por segundo faturável para edição de vídeo e referências de vídeo. Uma edição de 3,04 segundos sem duração é cobrada por 4 + 4 = 8 segundos.

Quais parâmetros Kling 4.0 são rejeitados?+

A rota rejeita mode=std/pro/4k, negative_prompt, watermark=true e audio=false. A validação e a sondagem da mídia acontecem antes do faturamento; gerações fracassadas são totalmente reembolsadas.

What model ID should I use for the Kling 4.0 API?+

Use kling-v4 in the model field. This is the stable PixMind route identifier shown in the playground request JSON.

Which endpoint does the Kling 4.0 API use?+

Send POST requests to /v1/generations. 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.
