Ideogram API parameters: every accepted value and what it costs

Every parameter the Ideogram v3 API accepts, taken from the schema that validates your request.

Parameter	Accepted values	Notes
prompt	any non-empty string	required
aspect_ratio	16:9, 9:16, 1:1, 4:3, 3:4	does not affect price
resolution	480p, 720p, 1080p	no price difference
n	1–4	linear cost, no batch discount
image_inputs	array of URLs	only the first entry is used, as the start frame
seed	integer	optional, for reproducibility
negative_prompt	string	optional; support varies upstream

The constraint worth knowing first

Note that n caps at 4. Batching saves round trips and concurrency slots, not money — cost is strictly linear.

A minimal call

curl -X POST https://genace.ai/api/v1/images/generations \
  -H "Authorization: Bearer $GENACE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"ideogram-v3","prompt":"..."}'

Omitted parameters take their defaults. The default call costs 6 credits ($0.06–$0.08 depending on which pack you bought).

Naming

Request bodies accept snake_case or camelCase — duration_sec and durationSec both work. Validation errors report the camelCase name, so a complaint about durationSec refers to the duration_sec you sent. See INVALID_PARAM.

What this page does not claim

These are the parameters Genace accepts and the prices Genace charges. The upstream vendor may expose more; anything not listed here is passed through extra untouched and is not validated on our side.
