Generación de imágenes

Genere y edite imágenes con un punto final unificado y compatible con OpenAI que se distribuye en Flux, Nano-Banana, Wan y más.

POST /v1/images/generations

Compatible con OpenAI images.generate SDK. Los parámetros específicos del proveedor conviven con los estándar: el backend transmite lo que entiende cada modelo.

Parámetros comunes

Parameter	Type	Required	Description
model	string	Required	Image model ID. Filter /v1/models by output_modalities.includes("image").
prompt	string	Required	Image description.
n	integer	Optional	Number of variations to generate per request. Capped by the model's image_caps.max_n.
size	string	Optional	OpenAI-style WxH, e.g. "1024x1024". Provider-specific values pass through.
aspect_ratio	string	Optional	Alternative to size. "16:9", "1:1", "9:16", … Validated against image_caps.aspect_ratios.
quality	string	Optional	"standard" \| "hd" (OpenAI) or model-specific labels. Validated.
response_format	string	Optional	"url" (default) or "b64_json".
seed	integer	Optional	Reproducibility seed. Same prompt + same seed = same image (where the upstream supports it).
input_images	array	Optional	[{ url? } \| { b64_json? }] for image-to-image / reference / first-frame.
sse	boolean	Optional	When true the response is sent as Server-Sent Events. The full JSON arrives in one event followed by [DONE]. Useful to keep long upstream renders from timing out at proxies.

Ejemplo básico

curl https://api.airforce/v1/images/generations \
  -H "Authorization: Bearer sk-air-YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "flux-2-dev",
    "prompt": "A cute baby sea otter floating on its back",
    "n": 1,
    "response_format": "url"
  }'

Forma de respuesta

Parameter	Type	Required	Description
created	integer	Optional	Unix timestamp.
data	array	Optional	Generated assets.
data[].url	string	Optional	Pre-signed CDN URL when response_format is "url".
data[].b64_json	string	Optional	Base64-encoded PNG when response_format is "b64_json".
data[].revised_prompt	string	Optional	Some models rewrite the prompt before generating; the rewritten version is returned here.

{
  "created": 1715000000,
  "data": [{
    "url": "https://cdn.api.airforce/images/abc123.png"
  }]
}

Variante de transmisión

Aprobar sse: true al realizar proxy a través de middleware que tiene tiempos de inactividad ajustados. La respuesta es un evento SSE con el JSON completo, luego [DONE].

data: {"created":1715000000,"data":[{"url":"https://cdn.api.airforce/images/abc123.png"}]}

data: [DONE]

Imagen a imagen y referencia

Modelos con image_caps.max_input_images > 0 aceptar imágenes de referencia. Pase URL o datos codificados en base64.

curl https://api.airforce/v1/images/generations \
  -H "Authorization: Bearer sk-air-YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "flux-2-dev",
    "prompt": "Same character, now in a snowy forest",
    "aspect_ratio": "16:9",
    "input_images": [
      {"url": "https://example.com/character.jpg"}
    ]
  }'

Parámetros específicos del modelo

Más allá de los parámetros comunes anteriores, las familias de modelos individuales aceptan extras. Los parámetros desconocidos se envían al canal ascendente tal cual, por lo que cualquier mando específico del proveedor futuro también funcionará sin una actualización del SDK.

Flux

flux-2-klein-4b, flux-2-klein-9b, flux-2-dev

Parameter	Type	Required	Description
aspect_ratio	string	Optional	"1:1", "16:9", "9:16", "4:3", "3:4", "21:9", "9:21".
image_urls	array	Optional	Reference images for img2img mode.

Nano-Banana

nano-banana-2, nano-banana-2-search, nano-banana-pro

Parameter	Type	Required	Description
aspect_ratio	string	Optional	"1:1", "16:9", "9:16", "4:3".
resolution	string	Optional	"512", "1024", "2048".
image_urls	array	Optional	Reference images.

Suno (music via /v1/images/generations)

suno-v4.5, suno-v5 — Suno historically routes through this endpoint. Native music API at /v1/audio/music is preferred for new code.

Parameter	Type	Required	Description
custom	boolean	Optional	Switch from "auto" to fully custom mode.
instrumental	boolean	Optional	Suppress vocals.
style	string	Optional	Genre tag list, e.g. "EDM, Bass".

Descubriendo capacidades

Cada modelo de imagen expone image_caps en /v1/models para que los clientes puedan validar las entradas antes de enviar:

Parameter	Type	Required	Description
image_caps.max_n	integer	Optional	Maximum n per request.
image_caps.aspect_ratios	array	Optional	Allowed aspect_ratio values.
image_caps.qualities	array	Optional	Allowed quality values.
image_caps.sizes	array	Optional	Allowed size values when applicable.
image_caps.max_input_images	integer	Optional	0 = text-only model. Higher = supports reference images.
image_caps.price_per_image_cents	integer	Optional	Cost per generated image. Multiply by n for the total request cost.
