Referencia API

Convenciones comunes

URL base

Todos los endpoints se sirven bajo el prefijo /v1.

Autenticación

Las llamadas a los endpoints /v1/* usan autenticación de Clave API (no JWT). La clave API se pasa mediante el siguiente encabezado:

Las claves faltantes o inválidas devuelven 401.

Verificación previa de saldo

Todos los endpoints de llamada a modelos ejecutan una verificación previa de saldo antes de la ejecución:

• Un saldo insuficiente devuelve Insufficient credit, asignado a:
  • Protocolo OpenAI: HTTP 400, code = insufficient_quota
  • Protocolo Anthropic: HTTP 402, type = billing_error
• Algunos endpoints también estiman un costo mínimo por modelo para una segunda verificación previa.

Descripción de campos de niveles de precio

Los 4 endpoints de consulta de modelos /v1/models, /v1/models/{model}, /v1/image-models y /v1/video-models devuelven el precio de facturación efectivo para el llamante (usuario de API Key), totalmente consistente con el cobro real, y devuelven todos los niveles de precio del modelo.

Diferencia de nomenclatura: /v1/models y /v1/models/{model} usan el estilo OpenAI snake_case (price_tiers); /v1/image-models y /v1/video-models usan camelCase (priceTiers). Ambas estructuras son idénticas.

price_tiers / priceTiers es un array; cada elemento es un nivel de precio:

Los tres tipos de modelo comparten la misma estructura; solo varía el relleno de los campos descriptivos. Los campos no aplicables son null:

Significado del precio: los valores inputPrice / outputPrice / cacheReadPrice / cacheWritePrice devueltos son los precios unitarios de facturación finales para el usuario de API Key actual tras resolver la cadena de precios (chain)→ guidance → precio base, consistentes con el cobro real. El precio unitario que ve el llamante varía según la cadena de precios a la que pertenece (reseller / distributor / empresa / configuración a nivel de usuario).

Deducción real = uso ÷ quantity × precio unitario correspondiente × ratio. Para video por segundos: deducción real = duration × outputPrice × ratio.

Límites y manejo de excepciones (los endpoints de solo lectura no devolverán 500 por problemas de configuración de precios)

Create Video GenerationPOSThttps://api.basicrouter.ai/api/v1/video-generations

Envía asíncronamente una tarea de generación de video. Devuelve un taskId inmediatamente; recupere el resultado consultando GET /v1/video-generations/{taskId} o a través de un webhook callbackUrl.

El model, los valores permitidos de videoType, el rango de duración (videoDurationMin/Max), la resolution / ratio soportadas y el límite de subida de recursos de referencia (fileMax) deben obtenerse primero de GET /v1/video-models. Solo se aceptan los códigos de videoType listados en allowedVideoTypes de ese modelo.

Ejemplos para cada videoType:

1. Texto a video (videoType=1)

Genera un video solo a partir de un prompt de texto; no se necesitan recursos de referencia.

Copiarcurl --request POST \
  --url https://api.basicrouter.ai/api/v1/video-generations \
  --header "Authorization: Bearer $BASICROUTER_API_KEY" \
  --header "Content-Type: application/json" \

    "videoType": 1,
    "text": "A cat jumping on a bed",
    "resolution": "480p",
    "ratio": "16:9",
    "duration": 4,
    "model": "seedance-2.0"
  }'

2. Imagen a video - primer frame (videoType=2)

Proporcione un único frame inicial en imageUrls; el modelo genera un video que comienza desde ese frame.

Copiarcurl --request POST \
  --url https://api.basicrouter.ai/api/v1/video-generations \
  --header "Authorization: Bearer $BASICROUTER_API_KEY" \
  --header "Content-Type: application/json" \

    "duration": 4,
    "model": "seedance-2.0",
    "imageUrls": ["https://basicrouter-flie.oss-accelerate.aliyuncs.com/test/first-frame.png"]
  }'

3. Imagen a video - primer y último frame (videoType=3)

Proporcione tanto el primer como el último frame en imageUrls (orden: [primero, último]); el modelo genera un video de transición entre los dos frames.

Copiarcurl --request POST \
  --url https://api.basicrouter.ai/api/v1/video-generations \
  --header "Authorization: Bearer $BASICROUTER_API_KEY" \
  --header "Content-Type: application/json" \

      "https://basicrouter-flie.oss-accelerate.aliyuncs.com/test/last-frame.png"
    ]
  }'

4. Imagen a video - referencia (videoType=4)

Proporcione una o más imágenes de referencia en imageUrls; el modelo usa su estilo/contenido como referencia (no como primer/último frame forzado) para generar el video.

Copiarcurl --request POST \
  --url https://api.basicrouter.ai/api/v1/video-generations \
  --header "Authorization: Bearer $BASICROUTER_API_KEY" \

      "https://basicrouter-flie.oss-accelerate.aliyuncs.com/test/ref-2.png"
    ]
  }'

5. Toda referencia (videoType=5)

Referencias mixtas de imagen / video / audio. Referencie recursos por posición en el prompt: la 1ª entrada en imageUrls es @图片 1, la 1ª en videoUrls es @视频 1, la 1ª en audioUrls es @音频 1. videoUrls también acepta cadenas de URL simples.
