When using mobile proxies for http://hackmd.io online activities such as data scraping, it is critical to confirm that the proxy is genuinely operating from the promised country. IP geolocation APIs serve as a essential verification system to validate the physical location associated with an IP address. These APIs analyze the IP and return details like country, region, city, postal code, latitude, longitude, and sometimes even the ISP or mobile carrier.

To begin, choose a trusted geolocation service such as GeoLite2. Sign up for an account and obtain an API key, which you will use to authorize your calls. Next, retrieve the visible IP of the mobile proxy you are testing. This can be done by sending a request to a service like ident.me from within the proxy environment. Once you have the IP, make an HTTP GET request to the geolocation API endpoint, including your API key in the request headers.

The API will respond with a structured data payload containing the location data. Compare this data against the intended region of the mobile proxy. For example, if the proxy claims to be in Seoul, South Korea, verify that the response includes South Korea as the nation and Seoul as the urban center.

Be aware that some proxies may return false geography due to mobile network NAT changes. To improve accuracy, use a multi-source verification approach. Additionally, monitor for consistency over time. A mobile proxy that shows inconsistent carrier info may be unreliable.

Always handle call thresholds and respect the provider’s usage policies. Implement request monitoring for failed requests and consider caching results to reduce unnecessary calls. Using IP geolocation APIs in this way helps ensure that your mobile proxies are delivering accurate geo-coverage and reduces the risk of being detected as fraudulent for using spoofed IP regions.
