Detect an image

Checks a photo or a still image for AI generation and editing, and answers with one verdict and one score for the whole image.

Send the file

curl -X POST \
  "https://api.scam.ai/v1/detections" \
  -H "x-api-key: <YOUR_API_KEY>" \
  -F "file=@/path/to/photo.jpg"

Images are sent as a file. A link to an image is fetched too; see Detect from a link.

Parameters

Request parameters
FieldTypeMeaning
filebinaryThe media file. JPG, PNG or WEBP; HEIC is not accepted, at most 10 MB.

The response

idstring
The detection id. Pass it to GET /v1/detections/{id} to read the run back.
statusstring
Always "completed". The answer arrives in the same request.
created_atstring
When the run finished. RFC 3339, millisecond precision, always Z.
mediaobject
What was checked: type (image, video or audio), filename, mime_type and bytes. The last three can be null when they were not known. mime_type is what the upload declared, so a client that sends no content type sees application/octet-stream here; type comes from the bytes themselves.
modelstring
The Eva version that answered this run, "Eva V1.5" or "Eva V1.6". Which version answers is set per account.
verdictstring
LIKELY_REAL, ALERT or LIKELY_AI. Branch on this.
scorenumber | null
0 to 1, the probability the media is AI-made or manipulated. null when nothing could be scored.
summarystring
One sentence a person can read, matching the verdict.
credits_usednumber
What this run cost, an integer. 0 on a sandbox key, or when the same file was sent byte for byte from this account within 30 days.
zero_charge_reasonstring
Only when credits_used is 0: "sandbox" or "duplicate".

Questions

Why did I get a 422 instead of a verdict?
For an image it means the bytes did not decode or the format is not supported: every decodable image is scored, with or without a face. The body carries a stable error.code; a refusal that names the content (reasons[], such as no_voice_content) happens on audio. Show it to your user; do not retry the same file. Nothing is charged. See Errors.
Do you keep the image?
Yes. Every run keeps the file and a history row, so it can be read back by id. Retention is covered by the privacy policy and DPA.
