{"name":"qr-maker","description":"Generates a scannable QR code from any text input: a URL, vCard, WiFi join string, or plain text. Send text plus optional format (png or svg), size, error_correction level, margin, and foreground/background hex colors; the endpoint returns data_base64 and content_type ready to embed or decode client-side. PNG requests are currently served as SVG-encoded data under the hood for Workers compatibility, so content_type reads image/svg+xml regardless of the format you request. Use it as a QR maker API, QR code generator, URL-to-QR converter, or text-to-QR tool for onboarding flows, business cards, and WiFi sharing.","price":"$0.001","method":"POST","input_schema":{"properties":{"text":{"type":"string","description":"Text to encode.
