How do I use a app store qr code with an API?
Send a POST request to the ChartQuery qrcode endpoint with your data as JSON. The API returns a rendered image directly. You can also use GET requests with URL parameters for simple cases. No API key is required for basic usage, anonymous access is available with 60 requests per hour.

Is the App Store QR Code API free to use?
Yes. The ChartQuery App Store QR Code API works without an API key. Anonymous access is rate-limited to 60 requests per hour and adds a small watermark. Authenticated users on paid plans get higher limits, no watermark, and longer chart persistence (6 months vs 3 days for shared URLs).
Can I customize the app store qr code appearance?
Yes. You have full control over colors, fonts, sizes, backgrounds, legends, and every visual property through the JSON configuration. The API uses Chart.js v4 for charts, and supports all native options for fine-grained customization.
Can I share and embed qr codes generated by the API?
Yes. Add "share": true to any request to get permanent URLs. The render_url is a direct image URL you can embed in emails, documents, or <img> tags. The view_url is an interactive HTML page you can embed as an iframe. No authentication needed for viewers.
