Supported output formats

Some of our pages / endpoints support outputting their data in multiple formats.

You can select a format either by using ?format=TYPE - which is high priority, or you can use the Accept: header.

You can also specify format as both an encoded POST form, or as JSON in the POST body.

Example Usage for format param and Accept header

curl https://minip.karabro.se/?format=json
curl -H 'Accept: application/json' https://minip.karabro.se/

curl https://minip.karabro.se/?format=yaml 
curl -H 'Accept: application/yaml' https://minip.karabro.se/

curl https://minip.karabro.se/lookup/45.132.234.123?format=yaml 
curl -H 'Accept: application/yaml' https://minip.karabro.se/lookup/45.132.234.123

# Using the HTTPie tool to send a JSON body POST request 
http -p hbHB POST https://minip.karabro.se/lookup/ format=plain addr=45.132.234.56

HTML

At the time of writing, currently only the index page ( / ), as well as this page ( /api/ ) support outputting their data in HTML format - though /api/ (this page) is purely a documentation page, and does not have any special functionality anyway.

HTML is used by default for the index page, however if needed, you can manually specify that you want HTML output by either passing format=html as a GET/POST (i.e. /?format=html) argument, or by ensuring that text/html is the highest priority in your Accept: header.

Matching types for format= and Accept: are:

html
text/html
text/x-html
text/xhtml
text/xhtml+xml
applicatiom/html
application/x-html
application/xhtml
application/xhtml+xml
web
page
webpage

JSON

The JSON format is available as a format option on the following endpoints:

/ (index - default format: html)
/lookup(/<ip>)(/<dtype>) (IP Lookup - default format: json)

Matching types for format= and Accept: are:

json
js
api
text/json
text/x-json
application/json
application/x-json
application/js

YAML (YML)

The YAML format is available as a format option on the following endpoints:

/ (index - default format: html)
/lookup(/<ip>)(/<dtype>) (IP Lookup - default format: json)

Matching types for format= and Accept: are:

yaml
yml
applicatiom/yaml
applicatiom/yml
applicatiom/x-yaml
applicatiom/x-yml
text/yaml
text/yml
text/x-yaml
text/x-yml

Plain Text

The Plain Text format is available as a format option on the following endpoints:

/ (index - default format: html)
/lookup(/<ip>)(/<dtype>) (IP Lookup - default format: json)
/flat(/<dtype>) (Simple flat connecting IP lookup for shellscripts - default format: plain)

Matching types for format= and Accept: are:

flat
plain
x-plain
plaintext
plain-text
text
text/*
text/plain
text/x-plain
text/plaintext
text/plain-text
application/text
application/plain
application/x-plain
application/plaintext
application/plain-text

Index Endpoint

The index endpoint at / - by default renders an HTML web page, designed to be read by humans. The HTML page displays the current IP you're connecting from - directly within the HTML body, while the IPv4/IPv6 sections are populated using JavaScript via AJAX queries to the JSON format of this endpoint on our v4 and v6-only domains.

Endpoints:

/
/index.txt
/index.yml
/index.yaml
/index.json
/index.html

Supported Output Formats

HTML (html) - This is the DEFAULT used for the index endpoint
Plain Text (plain) - Displays information about the IP and User Agent you're connecting from, in plain text. The plain text output is designed to be easy to parse using standard UNIX utilities such as grep, awk, sed, and/or even just using IFS= within shells like bash/zsh.
JSON (json) - Displays information about the IP you're connecting from, in JSON format.
YAML (yaml / yml) - Displays information about the IP you're connecting from, in YAML (YML) format.

Example Queries

JSON Output for Index Endpoint

On URLs which support JSON output, you can either pass the GET parameter ?format=json - or you can set the Accept header so that application/json is the most preferred content requested from the server.

You can query the main site to get information about your system's most preferred IP version, or if the client you're querying with (e.g. curl with -4 or -6) allows specifying the IP version, then you can select an IP version using your client.

curl https://minip.karabro.se/?format=json

# Alternative - send the header 'Accept: application/json'
curl -H 'Accept: application/json' https://minip.karabro.se/

# Make the request using IPv4
curl -4 https://minip.karabro.se/?format=json
# Make the request using IPv6
curl -6 https://minip.karabro.se/?format=json

Example Output:

{
    "error": false,
    "geo": {
        "as_name": "Karabro AB",
        "as_number": 51519,
        "city": "Malmö",
        "country": "Sweden",
        "country_code": "SE",
        "error": false,
        "ip_address": "2a0e:73c2:123::456",
        "lat": 55.598126,
        "long": 13.007398,
        "network": "2a0e:73c2::/32",
        "postcode": "211 54"
    },
    "hostname": "",
    "ip": "2a0e:73c2:123::456",
    "ip_type": "ipv6",
    "ip_valid": true,
    "messages": [],
    "ua": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:89.0) Gecko/20100101 Firefox/89.0"
}

Alternatively, you can query our IPv4-only / IPv6-only domain to force your client to use a specific IP version to obtain the results:

curl https://v4.minip.karabro.se/?format=json

curl https://v6.minip.karabro.se/?format=json

Plain Output for Index Endpoint

You can request plain text output from our index page using ?format=plain - or you can set your Accept to prioritise text/plain.

curl https://minip.karabro.se/?format=plain

# Alternative - send the header 'Accept: text/plain'
curl -H 'Accept: text/plain' https://minip.karabro.se/
