QR code with a logo
Your mark centred in the code, with the error correction raised automatically to cover what it hides.
Put a logo in a QR code now No key, no code — 2 credits either way.

Your mark centred in the code, with the error correction raised automatically to cover what it hides.
Embed a logo image at the centre of a QR code, raising error correction to compensate for the occlusion.
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.
Parameters
Generated from the endpoint’s own validation, so this is exactly what it accepts. A body field goes at the top level; an option goes inside options.
