Generate customizable QR codes with logos, gradients, custom shapes, colors, captions and frames. Export as PNG, SVG, JPEG, WebP, PDF or JSON with optional scan verification.
The API returns a generated QR code in various formats, including JSON, PNG, SVG, JPEG, WebP, or PDF. In JSON format, it includes a data URI along with metadata such as dimensions, verification status, QR version, and error correction level.
Key fields in the response include "format" (output format), "media_type" (MIME type), "width" and "height" (dimensions of the QR code), and "data_uri" (base64-encoded QR code image).
The endpoint accepts parameters for the data field (required), output format, image size, colors, error correction level, and style options such as module shapes and eye styles.
Users can customize requests by specifying optional parameters in the options object, such as output format, size, colors, and error correction level, as well as using the style object for visual appearance.
The response data is organized in a JSON object containing metadata and the QR code image. For non-JSON formats, the API directly returns the generated file without additional metadata.
Typical use cases include generating QR codes for URLs, text messages, event tickets, product information, and marketing materials, allowing easy access to information via mobile devices.
Users can utilize the returned data by embedding the QR code in websites, emails, or print materials. The data URI can be directly used in HTML image tags for web applications.
The API maintains data accuracy by implementing error correction levels, ensuring that QR codes remain scannable even if partially damaged. Users can select different error correction levels to suit their needs.

Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
You can monitor your API usage through the response headers included with every request:
x-zyla-api-calls-monthly-used: Shows the total number of API requests you have used during the current billing period.
x-zyla-api-calls-monthly-remaining: Shows the number of API requests you have remaining for the current billing period.
Yes, you can cancel your subscription at any time. Simply go to the Pricing section of the API you're subscribed to and click the "Unsubscribe" button.
Please note that upgrades, downgrades, and cancellations take effect immediately. Once your subscription is canceled, access to the service will end immediately, regardless of any remaining API calls in your quota.
