How this service works
Read the codes in an image URL: QR, Data Matrix, Aztec, PDF417, EAN-13, UPC, Code 128, Code 39... with format, content and position; flags URLs, crypto payment URIs (bitcoin:, ethereum:, solana:) and wifi credentials.
Output
Returns a JSON object with the number of codes found, an array of decoded codes each containing: format name (e.g. 'QR Code', 'EAN-13'), decoded content string, content type classification (url, crypto payment URI, wifi, plain text, etc.), and pixel position (top-left and bottom-right corners). Also includes the source image URL, dimensions, and a safety notice for URL-type codes.
Example use cases
Detect crypto payment URI in QR
“I have a QR code image at https://example.com/payment-qr.png — can you decode it and tell me if it contains a Bitcoin or Ethereum payment address?”
Extract Wi-Fi credentials from QR code
“This image has a Wi-Fi QR code on it: https://example.com/wifi-qr.jpg — please read it and give me the network name and password encoded inside.”
Decode product barcode from photo
“Can you read the EAN-13 or UPC barcode in this product photo and tell me what number is encoded in it? The image is at https://example.com/product-shelf.jpg”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/qr-barcode-read?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically decode any standard 1D or 2D barcode format from an image URL, especially when you also need structured metadata like bounding-box position, content type classification (URL vs crypto URI vs Wi-Fi), and safety flags. It supports a broader range of formats (QR, Data Matrix, Aztec, PDF417, EAN-13, UPC, Code 128, Code 39) than many single-format decoders.
Side effects
- Image URL is unreachable or returns a non-image response — no codes returned
- Image contains no detectable barcode or QR code — found_codes: 0
- Damaged or low-resolution barcode cannot be decoded by zxing-cpp
- Unsupported image format causing decoding failure
- Rate limiting or payment failure via x402 protocol
