How this service works
QR decoder / QR reader / scan QR from URL / QR code OCR / barcode reader / link extraction from QR. Reads QR codes out of any public image URL (PNG / JPG / GIF / BMP) and returns the decoded text strings. Multiple QR codes in a single image are returned as separate entries. Wraps qrserver.com's free public read-qr-code API (true DIY decode requires canvas, which Workers don't have natively). Returns an empty `codes` array plus a descriptive `note` if the image can't be fetched or no QR is found.
Output
Returns a JSON object with a `codes` array where each entry contains the decoded text string from a QR code found in the image. Multiple QR codes in the same image yield multiple entries. If no QR code is found or the image cannot be fetched, returns an empty `codes` array along with a descriptive `note` explaining what happened.
Example use cases
Example prompt
“Can you read the QR code in this image and tell me what it says? The image is at https://example.com/promo-flyer.png”
Technical details
Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/qr-code-decodeWhen to prefer
Use this endpoint when you have a public image URL containing a QR code and need to programmatically extract the encoded text or URL without requiring a mobile device or client-side canvas. Ideal for automation pipelines that receive flyer images, event tickets, or product photos and need to extract embedded QR data. Handles multiple QR codes in a single image gracefully.
Side effects
- Image URL is not publicly accessible — returns empty codes array with a note
- No QR code present in the image — returns empty codes array
- Unsupported image format — fetch or decode fails with a note
- Network timeout fetching the remote image — returns empty codes array
- Image exists but QR is too blurry or damaged to decode — returns empty codes array
