How this service works
Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.
Output
Returns a JSON object with 'found' (integer count of QR codes detected) and 'codes' (array of strings, each being the decoded text or URL from a detected QR code). If no QR codes are detected, found will be 0 and codes will be an empty array.
Example use cases
Decode QR code from product photo
“I photographed a product label that has a QR code on it — can you decode the QR code and tell me what URL or text it contains?”
Extract links from scanned document
“I scanned a flyer that has several QR codes printed on it. Can you read all of them and list the text or URLs they encode?”
Verify QR code content before printing
“I generated a QR code for my website but I want to double-check it actually encodes the right URL — can you decode this image and confirm what it says?”
