-# geoip-api
-
-HTTP API for converting an IPv4 address to a country code.
-
-Uses the [`iptoasn.com`](https://iptoasn.com) dataset.
-
-## Setup
-
-Grab the latest `ip2asn-v4.tsv.gz` and extract it to `data/ip2asn-v4.tsv`.
-
-Then just use `cargo` as usual.
-
-## Usage
-
-```shell
-$ http GET 'http://127.0.0.1:8000/192.168.0.1'
-```
-
-```json
-{
-  "asn": 0,
-  "country_code": "None",
-  "asn_desc": "Not routed"
-}
-```
