Description

Telize is a REST API built in C with Kore allowing to get a visitor IP address and to query location information from any IP address. It outputs JSON-encoded IP geolocation data, and supports both JSON and JSONP.

Geolocation operations are performed using libmaxminddb which caches the database in RAM. Therefore, Telize has very minimal overhead and should be blazing fast.

Requirements

Dependencies

Telize requires Kore 4.0.0+ and libmaxminddb.

GeoIP2 databases

Telize requires the free GeoLite2 databases from MaxMind.

The path to the GeoLite2 City and GeoLite2 ASN databases can be configured in conf/build.conf via the GEOIP2DIR macro, pointing to /var/db/GeoIP by default.

Building

Using the kodev tool:

kodev build

Configuration

By default, Telize will only listen on 127.0.0.1 and ::1. To add more listeners, bind directives should be added in conf/telize.conf in the server blocks.

Running

Using the kodev tool:

kodev run

Access logs

The default Telize configuration does not have logging enabled, it must be configured manually. There are commented out accesslog directives in conf/telize.conf for each domain block.

If your Telize instance produces lots of logs, Logswan might be of interest.

Telize and proxies

Telize handles the 'X-Forwarded-For' HTTP header if present, and returns data for the first IP address of the list.

CORS Support (Cross-origin resource sharing)

Telize has CORS enabled by default with the following policy:

Access-Control-Allow-Origin: *

Timezone offsets

Since version 3.0.0, Telize now dynamically calculates timezone offsets (UTC time offset) and adds data to the payload.

On Alpine Linux, the 'tzdata' package needs to be installed, otherwise localtime() will not return any data.

Usage

For complete API documentation and usage examples, please check the project site.

Get IP address in Plain text format

• Example: http://127.0.0.1:8080/ip

Get IP address in JSON format

• Example (JSON): http://127.0.0.1:8080/jsonip
• Example (JSONP): http://127.0.0.1:8080/jsonip?callback=getip

Get IP address location in JSON format

Calling the API endpoint without any parameter will return the visitor IP address:

• Example (JSON): http://127.0.0.1:8080/location
• Example (JSONP): http://127.0.0.1:8080/location?callback=getgeoip

Appending an IP address as parameter will return location information for the given address:

• Example (JSON): http://127.0.0.1:8080/location/46.19.37.108
• Example (JSONP): http://127.0.0.1:8080/location/46.19.37.108?callback=getgeoip
