Rate Limits
To ensure service availability, QR code generation is rate-limited per IP address. You can generate up to 20 codes in quick succession, after which the allowance replenishes at one code every 2 seconds.
Hotlinking QR codes directly from this API is fine for personal or low-traffic pages. For anything with significant traffic, please generate the code once and host the image yourself. The rate limits are set accordingly to keep the service available for everyone.
