Bild-Generierung

Generiere und editiere Bilder mit einem einheitlichen, OpenAI-kompatiblen Endpoint der zu Flux, Nano-Banana, Dirtberry, Wan und mehr fan-out.

POST /v1/images/generations

Direkt kompatibel mit dem OpenAI images.generate SDK. Provider-spezifische Parameter laufen neben den Standard-Parametern — das Backend leitet weiter was jedes Modell versteht.

Gemeinsame Parameter

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.

Einfaches Beispiel

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"
  }'

Response-Format

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"
  }]
}

Streaming-Variante

Übergib sse: true wenn du durch Middleware mit knappen Idle-Timeouts proxied. Die Response ist ein einzelnes SSE-Event mit dem kompletten JSON, dann [DONE].

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

data: [DONE]

Bild-zu-Bild & Referenz

Modelle mit image_caps.max_input_images > 0 akzeptieren Referenz-Bilder. Übergib entweder URLs oder base64-codierte Daten.

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"}
    ]
  }'

Modell-spezifische Parameter

Über die gemeinsamen Parameter oben hinaus akzeptieren einzelne Modell-Familien Extras. Unbekannte Parameter werden ungeprüft an den Upstream weitergeleitet, sodass auch zukünftige provider-spezifische Knöpfe ohne SDK-Update funktionieren.

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".

Capabilities entdecken

Jedes Bild-Modell exponiert image_caps auf /v1/models damit Clients Inputs vor dem Senden validieren können:

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.
