images-generate

Generate images with Ideogram 2a from a text prompt

Generate one or more images from a text prompt with Ideogram 2a, a fast, lower-cost model, with an optional style type. Set rendering_speed to turbo for even faster generation.

By default the request blocks until the images are ready and returns them in data. Set async to true to return immediately after the request is accepted, then poll for completion and results with GET /v1/generations/{generation_id} using the returned generation_id.

Supplying a webhook_url makes the request asynchronous whatever async says: the response returns as soon as the request is accepted, and the finished result is POSTed to that URL.

post/v2/image/generate/ideogram-2a

Query parameters

dry_runboolean

When true, the request is validated and priced but not run: nothing is generated, stored, or billed, and no safety review is performed. The response is a PriceQuote object instead of the usual response for this endpoint. Send exactly the request you would send to generate, so the quote reflects the same options.

Request body

promptstring required

The prompt to generate images from.

seedinteger

Random seed. Set for reproducible generation.

aspect_ratio'auto' | '1x3' | '3x1' | '1x2' | '2x1' | '9x16' | '16x9' | '10x16' | '16x10' | '2x3' | '3x2' | '3x4' | '4x3' | '4x5' | '5x4' | '1x1'

The aspect ratio for an Ideogram 3.x or 2.x generation. auto lets the model select a ratio from the prompt; any other value pins the ratio. Cannot be combined with resolution. Omitting the field is not auto: it uses 1x1.

rendering_speed'turbo' | 'default' | 'quality'

The rendering speed to use. turbo generates faster at a lower cost, while quality prioritizes the highest-quality result.

magic_prompt'auto' | 'on' | 'off'

Determine if MagicPrompt should be used in generating the request or not.

num_imagesinteger

The number of images to generate.

The style type to generate with. When omitted, the model's default styling is used; pass auto to have a style selected automatically from the prompt.

enable_copyright_detectionboolean nullable

Optional. Opt this request into post-generation copyright detection. Adds detection latency; flagged images come back with is_image_safe: false.

asyncboolean

When false (the default), the request blocks until the images are ready and returns them in data. When true, the request returns as soon as it is accepted; poll for completion and results with GET /v1/generations/{generation_id} using the returned generation_id.

webhook_urlstring uri

HTTPS URL that Ideogram delivers the generated result to. Ideogram sends a JSON POST to this URL once all images for the request have finished generating. The body mirrors the synchronous generate response: request_id, created, and a data array containing every generated image (url, prompt, resolution, seed, is_image_safe). Each delivery is signed with Ed25519 and verifiable against the public keys at https://api.ideogram.ai/v1/.well-known/jwks.json. Must be HTTPS; private and loopback hosts and the cloud metadata service are rejected.

privateboolean nullable

When true or omitted, the output is kept private to your account. Set to false to publish the output to the public feed. Enterprise accounts always generate privately.

target_collection_idstring

A collection you can write to, by its URL-safe base64 collection id. The output images are added to it when the request completes.

Example request

{
  "magic_prompt": "",
  "aspect_ratio": null,
  "async": false,
  "style_type": "realistic",
  "private": true,
  "seed": 12345,
  "rendering_speed": "default",
  "webhook_url": "https://api.example.com/webhooks/ideogram",
  "enable_copyright_detection": true,
  "target_collection_id": "target_collection_id",
  "prompt": "prompt",
  "num_images": 1
}

Response

The generated images (synchronous requests), or an acknowledgement to poll with GET /v1/generations/{generation_id} (async requests).

generation_idstring required

URL-safe base64 ID of the accepted generation. Accepted by the GET /v1/generations/{generation_id} polling endpoint.

seedinteger required

Random seed. Set for reproducible generation.
