Choose this endpoint when you need a quick, paid-per-call QR code generated from a URL, text, vCard, or Wi-Fi string and want a raw PNG back — especially in automated agent workflows where you need to embed a QR image in a document, flyer, or web page without setting up your own QR library.
Side effects

- Extremely long data strings may exceed QR code capacity and fail encoding

- Invalid size value (e.g. non-integer) may return a 400 error
