What it does

Also called: read a qr code from a picture · decode a qr code image · what does this qr code say.

Use it from your own code

The same endpoint this page calls — no daily cap, 2 credits a call either way.

POST /v1/codes/qr-decode

curl -X POST "$DOATHING_API/v1/codes/qr-decode" \
  -H "x-api-key: $DOATHING_KEY" \
  -H "content-type: application/json" \
  -d '{"file": {"filename": "screenshot.png", "content_type": "image/png", "data_b64": "<base64>"}}'

Point it at a screenshot or a photo and get the contents back as text.

Detect and decode QR codes present in an uploaded image, returning contents and positions.

Input

Send a file object with base64 data_b64, its content_type and a filename. Accepted types: image/png, image/jpeg, image/webp, image/gif, image/tiff.

The declared type is not trusted — the bytes are sniffed and a contradiction is rejected rather than corrected.

Response

The result carries your remaining balance alongside it, so you can track spend without a second call.

Cost

2 credits per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.

A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.
