Input

FieldKindDefaultDescription
prompt requiredtext—Text description of the desired image
nnumber (whole)
1 to 1
—Upper bound on the number of images to generate (1-10). Providers may return fewer images, and providers that only support single-image generation reject n > 1.
backgroundone of
auto, transparent, opaque
—Background treatment. `transparent` requires an output_format that supports alpha (png or webp).
resolutionone of
1K, 2K, 4K
—Normalized resolution tier of the generated image. Concrete pixel dimensions are derived per-provider.
aspect_ratioone of
1:1, 4:3, 3:4, 3:2, 2:3, 16:9, 9:16, 21:9, auto
—Normalized aspect ratio of the generated image. Providers clamp to their supported subset.
output_formatone of
png, jpeg, webp
—Encoding of the returned image bytes. Most models produce raster formats (png, jpeg, webp). SVG is supported by vectorization models (e.g. Quiver) — the SVG markup is UTF-8 base64-encoded in `b64_json`.
input_referencesnumber (whole)
0 to 10
—Reference images to guide image-to-image generation, as base64 data URLs or HTTP(S) URLs.
