Referência da API do Kling O3

Kling completo: criar, animar, referenciar e editar até 4K

Com uma única chave de API da PopNow você chama o Kling O3 direto do seu código. Aqui estão os IDs de modelo a enviar, cada campo de entrada aceito, quantos créditos custa cada requisição e um exemplo que você cola no terminal e roda.

As descrições dos parâmetros vêm do schema de entrada do modelo e estão disponíveis só em inglês.
