Input parameters

ParameterTypeRequiredDefaultLimits and description
promptstringYes—Maximum 5000 characters (platform limit); The positive prompt for the generation. Supports long, detailed prompts and Chinese and English text rendering inside the image.
aspect_ratiostringNo"1:1"1:1, 1:2, 2:1, 1:3, 3:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 9:21, 21:9; The aspect ratio of the generated image.

output_formatstringNo"jpeg"jpeg, png, webp; The format of the output image.
seedintegerNo—The random seed to use for the generation. -1 means a random seed will be used.

Only prompt is required. seed must be an integer; -1 requests a random seed. Resolution is an output pixel-count tier, not a fixed width or height. This Nami endpoint returns an asynchronous task and image URLs; the upstream enable_sync_mode and enable_base64_output switches are not exposed.

One image per request. List prices match WaveSpeed. USD 1 = 100 credits. Only resolution changes the price; aspect ratio, output format and seed add no fee. Account discounts apply separately.
