API Endpoint

POSThttps://api.segmind.com/v1/ideogram-4

Parameters

promptrequired
string

Describe the image; put exact in-image text in quotes. More detail improves design and typography.

Default: "A vintage-style travel poster of Tokyo at night, glowing neon signs reflecting on wet streets, a bold title reading \"TOKYO\" across the top and the tagline \"Where Tradition Meets Tomorrow\" below, vibrant teal and magenta palette, clean retro print design"
enable_prompt_expansionoptional
boolean

LLM expands your prompt for richer detail. Disable when exact in-image text must stay unchanged.

Default: true
enable_safety_checkeroptional
boolean

Filters unsafe content from outputs. Keep enabled for production and public-facing apps.

Default: true
image_sizeoptional
string

Output aspect ratio and resolution. Portrait suits posters, landscape banners, square_hd is default.

Default: "square_hd"
Allowed values :
"square_hd""square""portrait_4_3""portrait_16_9""landscape_4_3""landscape_16_9"
num_imagesoptional
integer

Images generated per request, 1 to 8. Raise to compare variations in one call.

Default: 1Range: 1 - 8
output_formatoptional
string

Image file format. jpeg for smaller files, png for transparency and crisp text edges.

Default: "jpeg"
Allowed values :
"jpeg""png"
rendering_speedoptional
string

Speed/quality tradeoff. Use QUALITY for text-heavy design, TURBO for fast cheap drafts.

Default: "QUALITY"
Allowed values :
"TURBO""BALANCED""QUALITY"
seedoptional
integer

Random seed; -1 randomizes. Fix a value to reproduce the same image across runs.

Default: 123456Range: 100 - 999999

Response Type

Returns: Text/JSON

Asynchronous requests (v2)

Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.

  1. 1
    POST /v2/ideogram-4

    Submitreturns request_id, status_url, response_url

  2. 2
    GET /v2/requests/{id}/status

    Polluntil COMPLETED or FAILED

  3. 3
    GET /v2/requests/{id}

Status states

QUEUEDAccepted, waiting for a worker
PROCESSINGRunning on a worker
COMPLETEDDone — result body is ready
FAILEDErrored (incl. content/RAI blocks)
  • A FAILED request is served as HTTP 422 — the body still carries the error detail.
  • An unknown or expired request_id returns HTTP 404.
  • Results are retained for 1 hour, then expire.
  • Content / RAI blocks surface as FAILED, not a separate state.
  • Track completion by polling the status endpoint.
