Generate a QR code for any text or URL

Generate a QR code for any text or URL. Returns image_base64 (base64 PNG; decode to get raw bytes). Params: text (required), size in px (64-1024, default 256), error_correction (L/M/Q/H, default M). H = highest redundancy, survives up to 30% damage.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
