JSON output

$ http 127.0.0.1:18081/json
{
  "ip": "18.206.13.28",
  "ip_decimal": 315493660,
  "country": "United States",
  "country_eu": false,
  "country_iso": "US",
  "city": "Ashburn",
  "hostname": "ec2-18-206-13-28.compute-1.amazonaws.com",
  "latitude": 39.0481,
  "longitude": -77.4728,
  "user_agent": {
    "product": "CCBot",

    "comment": "(https://commoncrawl.org/faq/)",
    "raw_value": "CCBot/2.0 (https://commoncrawl.org/faq/)"
  }
}

Setting the Accept: application/json header also works as expected.

FAQ

How do I force IPv4 or IPv6 lookup?
