# Generación de imágenes Seedream-5.0-Lite

>  - Modo de procesamiento asíncrono, devuelve un ID de tarea para consultas posteriores
- Admite múltiples modos de generación, incluidos text-to-image, image-to-image y generación secuencial de imágenes
- Admite resoluciones 2K / 3K con formatos de salida PNG / JPEG
- Los enlaces de las imágenes generadas son válidos durante 72 horas; guárdelos cuanto antes

## Autorización

**Authorization** `string` *required*

Todos los endpoints de la API requieren autenticación mediante Bearer Token

Obtenga su clave de API:

Visite la [página de gestión de claves de API](https://gccai.heqingsong.uk/keys) para obtener su clave de API

Añádala a la cabecera de la solicitud:

```
Authorization: Bearer YOUR_API_KEY
```

## Cuerpo de la solicitud

**model** `string` *required* (default: seedream-5-0-lite)

Nombre del modelo de generación de imágenes

Modelos admitidos: `seedream-5-0-lite`, `seedream-5.0-lite`, `Seedream-5.0-lite`

Ejemplo: `"seedream-5-0-lite"`

**nsfw\_check** `boolean` (default: false)

Indica si se debe moderar el contenido antes de enviar la tarea de imagen.

* `true`: revisar los prompts y las imágenes de entrada con `omni-moderation-latest`
* `false` u omitido: no enviar una solicitud de moderación, sin coste ni latencia de moderación adicionales (predeterminado)

**prompt** `string` *required*

Descripción textual para la generación de la imagen

**size** `string` (default: 1:1)

Proporción de la imagen

Proporciones admitidas:

* `1:1` - Cuadrado (predeterminado)

* `1:2` - Formato vertical alargado
* `21:9` - Ultrapanorámico
* `auto` - Ajusta automáticamente la proporción según la imagen de referencia (requiere `image_urls`)

`2x1` equivale a `2:1` y `1x2` equivale a `1:2`. La `x` debe escribirse en minúscula y no se admiten espacios.

> **Nota:** Seedream-5.0-Lite no admite la proporción `9:21`

**resolution** `string` (default: 2K)

Resolución de la imagen

Resoluciones admitidas:

* `2K` - Resolución estándar (predeterminada)
* `3K` - Alta definición
* `4K` - Ultra alta definición

> **Nota:** Seedream-5.0-Lite admite resoluciones 2K, 3K y 4K, y no admite 1K

**Tamaños de referencia por resolución:**

| 21:9 | 6240×2656 |

**n** `integer`

Número de imágenes a generar

Rango: 1-15

Predeterminado: 1

**Nota:**

* Cuando `n > 1`, se activa automáticamente el modo de generación secuencial de imágenes
* **Debe indicar un número simple (por ejemplo, `1`); no use comillas o se producirá un error**

El cobro se descontará por adelantado según la cantidad

> [!NOTE]
>
> La cantidad de imágenes de referencia en `image_urls` + la cantidad final de imágenes generadas especificada por `n` debe ser ≤ 15.

**image\_urls** `array`

Lista de URL de imágenes de referencia para la generación image-to-image

Se admiten dos formatos:

**1. URL completa de la imagen**

* URL de imagen de acceso público (http\:// o https\://)
* Ejemplo: `https://example.com/image.jpg`

**2. Formato codificado en Base64**

* **Es obligatorio usar el formato Data URI completo**
* Formato: `data:image/{format};base64,{base64data}`
* Formatos de imagen admitidos: jpeg, png
* Ejemplo: `data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYABg...`
* ⚠️ Nota: el prefijo `data:image/jpeg;base64,` es obligatorio

**Limitaciones:**

* Formatos de imagen: jpeg, png
* Rango de proporción (ancho/alto): \[1/3, 3]
* Ancho y alto (px) > 14
* Tamaño: no superar los 10MB por imagen
* Píxeles totales: no superar 6000×6000 px

> [!NOTE]
>
> La cantidad de imágenes de referencia en `image_urls` + la cantidad final de imágenes generadas especificada por `n` debe ser ≤ 15.

**output\_format** `string` (default: jpeg)

Formato de salida de la imagen

* `jpeg`: formato JPEG (predeterminado)
* `png`: formato PNG, adecuado para fondos transparentes y casos similares

> **Nota:** El parámetro `output_format` es exclusivo de Seedream-5.0-Lite. Otros modelos de imagen ignorarán este parámetro.

**sequential\_image\_generation** `string` (default: disabled)

Modo de generación secuencial de imágenes

Controla si se generan múltiples imágenes:

* `disabled`: desactiva el modo secuencial (predeterminado)
* `auto`: activa el modo secuencial; permite generar múltiples imágenes

**Notas de uso:**

* Cuando `n > 1`, se configurará automáticamente como `auto`

**sequential\_image\_generation\_options** `object`

Opciones de generación secuencial de imágenes

Disponible cuando `sequential_image_generation` se establece como `auto`

**Propiedades:**

* `max_images` (integer): especifica el número de imágenes a generar

**Ejemplo:**

```json theme={null}
"sequential_image_generation": "auto",
"sequential_image_generation_options": {
  "max_images": 4
}
```

**watermark** `boolean` (default: false)

Indica si debe añadirse una marca de agua a la imagen generada

* `true`: añadir marca de agua
* `false`: sin marca de agua (predeterminado)

## Respuesta

**code** `integer`

Código de estado de la respuesta

**data** `array`

Array de datos de la respuesta

**Propiedades**

**status** `string`

Estado de la tarea

* `submitted` - Enviada
