X-API-Key
string
header

Body

application/json

Request body for the enhance endpoint.

Enhances the provided input image without requiring a text prompt, aspect ratio, or resolution -- those parameters are inferred automatically.

The image can be provided as a raw base64-encoded string or a publicly accessible URL. Both formats are accepted and detected automatically.

​
image
string
required

Input image as a raw base64 string or publicly accessible URL. Supported formats: JPEG, PNG, WebP, and HEIC/HEIF. Images larger than 4K (4096px) are automatically resized; for best results, provide images at 4K or below.

​
profile_ids
string[]

Subset of your account's profiles relevant to this request. Your account holds all profiles, but only pass the ones belonging to the end-user whose photo is being edited. These profiles serve as candidates for identity preservation. The fewer profiles you pass, the easier it is for our system to determine which profiles are relevant.

​
num_output_images
integer
default:1

Number of output images to generate (1-4).

Required range: 1 <= x <= 4
​
output_format
enum<string>
default:png

Output image format (png, jpg). Default: png (will change to jpg on 2026-05-08).

Available options:
png,
jpg
​
response_mode
enum<string>
default:bytes

Response delivery mode. 'bytes': return base64-encoded image data (default). 'urls': return signed download URLs (24-hour expiry) instead of image bytes.

Available options:
bytes,
urls
​
prompt
string | null

Optional text instructions to guide the enhancement.

Response

Response returned by the edit, generate, and enhance endpoints.

​
known_subjects
KnownGeneratedSubjectCounts · object
required

Dictionary mapping a known subject's profile_id to the number of times they were generated. If multiple variations are generated, this will be the aggregated count across all variations.

​
