Why this API

Built for production. Tested before every export.

Same engine. No quality penalty.

The API hits the same renderer the consumer builder uses. Same validation pipeline, same shape catalogue, same output formats.

ISO 18004 validated server-side.

Every export runs through contrast + decode checks. If a QR can't be scanned, the engine fixes it or returns a structured error — never silent garbage.

Bring your own LLM key.

Bring your own key — nine major LLM providers supported (OpenAI, Anthropic, Google, Mistral, Cohere, Groq, xAI, DeepSeek, Qwen), plus self-hosted models via any OpenAI-compatible endpoint (Ollama, LM Studio).

50+ design parameters.

Module shapes, finder eyes, gradients, frames, center text, logos, scan corners. No theming engine — the engine itself is the theme.

PNG, SVG, PDF, WebP, JPG.

Vector for print, base64 for embeds, binary for downloads. One flag (responseType) flips between JSON and raw.

118 pre-baked templates.

Don't want to handcraft? Call /api/qr/templates/{id}/generate with your URL and skip the design step.

Copy-paste ready

Generate a QR in 6 lines, in your language.
