     Content-Type: application/json

DESCRIPTION

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.

INPUT — request schema

EXAMPLES — two ways to call

EXAMPLE 1 · curl

curl -X POST https://x402.org/v1/qr-code-decode \
  -H 'Content-Type: application/json' \
  -d '{ }'

first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.

EXAMPLE 2 · mcp

# install once
claude mcp add x402 --command "npx x402-deployer-mcp"

# then ask Claude Code:
