Autorizaciones
string
requerido
Todos los endpoints de la API requieren autenticación con Bearer TokenObtenga su API Key:Visite la página de gestión de API Keys para obtener su API KeyAñádala al encabezado de la solicitud:
Authorization: Bearer YOUR_API_KEY
Body
string
predeterminado:"gemini-3.1-flash-lite-image"
requerido
Nombre del modelo de generación de imágenesSe admiten los siguientes nombres de modelo:
gemini-3.1-flash-lite-image(Nano Banana Lite, alias compatiblenano-banana-2-lite)gemini-3.1-flash-lite-image-ext(alias compatiblenano-banana-2-lite-ext)
Ambos tienen los mismos parámetros y restricciones (solo 1K, no admiten
google_search / official_fallback, hasta 14 imágenes de referencia). Ninguno tiene variante -official ni admite el parámetro de respaldo official_fallback. La facturación depende de la configuración del backend de cada canal.Los alias nano-banana-2-lite (correspondiente a gemini-3.1-flash-lite-image) y nano-banana-2-lite-ext (correspondiente a gemini-3.1-flash-lite-image-ext) son equivalentes a sus nombres originales respectivos y pueden usarse de forma intercambiable.string
requerido
Descripción textual para la generación de la imagen
string
Proporción de la imagenProporciones compatibles:
auto- Elige automáticamente la proporción1:1- Cuadrada, avatares, redes sociales3:2/2:3- Fotografías estándar4:3/3:4- Proporción de pantalla tradicional16:9/9:16- Pantalla panorámica / portadas de video vertical5:4/4:5- Imágenes de Instagram21:9- Banner ultra panorámico
En texto a imagen, cuando
size es auto, el valor predeterminado es 1:1 o 16:9; en imagen a imagen, la proporción sigue la respuesta del upstream. Se recomienda especificar una proporción.string
predeterminado:"1K"
Resolución de la imagen de salidaValores compatibles:
1K- ~1024px, resolución estándar (Lite solo admite esta opción)
Lite solo admite 1K. Enviar
2K / 4K / 0.5K se degrada silenciosamente a 1K, sin generar error ni producir realmente una resolución más alta. La interfaz de usuario no necesita exponer la opción de resolución.integer
predeterminado:"1"
Número de imágenes a generarRango: 1 ~ 4, predeterminado
1Cuando n>1, el backend realiza varias solicitudes concurrentes al upstream y factura según el número de imágenes realmente generadas con éxito. Se recomienda enviar siempre 1 desde el frontend (muestra el progreso imagen por imagen y una facturación más clara).⚠️ Nota: Debe introducirse como número puro (p. ej., 1), no use comillas o se producirá un errorarray
Lista de URLs de imágenes de referencia para generación de imagen a imagenSe admiten dos formatos:1. URL completa de la imagen
- URL de imagen accesible públicamente (http:// o https://)
- Ejemplo:
https://example.com/image.jpg
- Debe usar el formato completo Data URI
- Formato:
data:image/{格式};base64,{base64数据} - Formatos de imagen compatibles: jpeg, png, webp
- Ejemplo:
data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYABg... - ⚠️ Nota: Debe incluir el prefijo
data:image/jpeg;base64,
- Máximo 14 imágenes de referencia (recomendado: hasta 10 referencias de objeto + 4 de personaje)
- Tamaño por imagen: no debe superar 10MB
- Formatos compatibles: jpeg, png, webp
string
Dirección de callback de la tarea (base)Cuando la tarea tiene éxito o falla, la plataforma llama a
webhook + /callback (no reenvía al upstream). Enviar este parámetro reduce significativamente el sondeo; aun así se recomienda mantener el sondeo como respaldo.Puntos clave de uso de Lite
- No admite
google_search/google_image_search: Lite usa el endpointinteractionsde la Developer API, y el upstream no habilita la herramienta Search (devuelve “Search as tool is not enabled for this model”); el adaptador de la plataforma tampoco envía ese parámetro. Enviarlo no genera error y la imagen se genera con normalidad, pero sin ningún efecto de mejora por búsqueda. Si necesita mejora por búsqueda, usegemini-3.1-flash-image-preview. - No admite el repintado parcial con
mask_url(la serie Gemini usa aspect ratio + imágenes de referencia, no máscaras). - Facturación por token (a diferencia del precio fijo por imagen de flash/pro): entrada ~0.25pormilloˊndetokens,salidadeimagen 30 por millón de tokens; una imagen 1K ≈ 1120 tokens de salida ≈ $0.0336 por imagen. El precio real depende de la configuración de multiplicador del backend.
- Todas las imágenes generadas incluyen la marca de agua invisible SynthID de Google (comportamiento del upstream, no se puede desactivar).
