Options
Some options can be passed with the request as query parameters

  level=l                                                 # Sets the error correction level to low (7%)
  level=m (default)                                       # Sets the error correction level to medium (15%)
  level=q                                                 # Sets the error correction level to quartile (25%)
  level=h                                                 # Sets the error correction level to high (30%)

  out=shell (if http header Accept=*/*)                   # The QR code is created from shell control characters
  out=block (default)                                     # The QR code is created from Unicode blocks
  out=square                                              # The QR code is created from Unicode squares

  raw                                                     # Does not parse the QR code text, instead creates
                                                          # the QR code from the text as is



URL encoding the payload
In addition to passing the QR code text as path parameter (curl qrcd.to/Hello%20World) you can pass it as a query
parameter "text" (curl "qrcd.to?text=Hello%20World"). This allows using curls --data-urlencode setting to URL encode
the text.

  $ curl -G --data-urlencode "text=Hello World" qrcd.to
  $ curl -G --data-urlencode "text=mail:hello@qrcd.to:Hello:Hello qrcd.to. This message contains spaces." qrcd.to

The query parameter text is appended to the path parameter text.



Piping to stdin
  $ echo -n hello | curl -G --data-urlencode text@- qrcd.to
