Description
Telize is a REST API built in Go 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 the MaxMind DB Reader for Go which caches the database in RAM. Therefore, Telize has very minimal overhead and should be blazing fast.
Requirements
Telize requires the following Go libraries:
- chi: lightweight, idiomatic and composable router - https://github.com/go-chi/chi
- maxminddb-golang: MaxMind DB Reader for Go - https://github.com/oschwald/maxminddb-golang
GeoIP2 databases
Telize requires the free GeoLite2 databases from MaxMind.
Telize will look for the GeoLite2 City and GeoLite2 ASN databases in
/var/db/GeoIP by default.
Installation
Build and install with the go tool, all dependencies will be automatically
fetched and compiled:
go build
go install telize
Usage
By default, Telize will bind on localhost, port 8080.
USAGE:
-host string
Set the server host (default "127.0.0.1")
-port string
Set the server port (default "8080")
-version
Display version
Running Telize at boot time
Systemd unit file
Telize is bundled with a systemd unit file, see: systemd/telize.service
Copy the systemd/telize.service file in /etc/systemd/system and the Telize
binary in /usr/local/sbin.
To launch the daemon at startup, run:
systemctl enable telize
Making Queries
For complete API documentation and usage examples, please check the project site.
Telize supports JSONP callbacks.
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=getlocation
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=getlocation
Client Errors
When incorrect user input is entered, the server returns an HTTP 400 Error (Bad Request), along with a JSON-encoded error message.
- Code 401: Input string is not a valid IP address
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.
