Configura cada cliente de la forma correcta

Elige una herramienta en la columna izquierda para ver la guía completa. El contenido de abajo usa tu API key actual y la Base URL real del sistema.

Volver a los precios Consola

Preparativos antes de configurar

  • Recarga saldo y asegúrate de tener una API key en la consola de AI API.
  • Usa la Base URL correcta para cada cliente: algunos necesitan `/v1`, otros no.
  • Elige un modelo activo de la tabla de precios y evita modelos con rutas desactivadas.
  • Si el cliente admite endpoint personalizado, usa siempre el endpoint HTTPS de este sitio.

Reglas de la Base URL

  • Clientes compatibles con OpenAI: usa la Base URL con `/v1`.
  • Claude Code `ANTHROPIC_BASE_URL`: usa el dominio raíz, sin `/v1`.

Contract rule

Both text-to-image and image-to-image use POST /images/generations when that is the model contract. Do not rename the image field: use the payload template/contract of the selected model. Do not substitute images/edits or images/variations for a model that exposes only images/generations.
