Rust IP Geolocation API Example

Use Rust reqwest to send your IPRout key in the Authorization header, apply a 10-second timeout, reject non-success HTTP statuses, and parse the JSON response. Keep IPROUT_API_KEY in the server environment rather than source code or a browser bundle.

How do I call IPRout with Rust?

This example looks up 8.8.8.8 unless the client example uses /ip to demonstrate caller lookup. Replace only the route when switching modes.

let client = reqwest::Client::builder().timeout(Duration::from_secs(10)).build()?;
let response = client
    .get("https://api.iprout.com/ip/8.8.8.8")
    .bearer_auth(std::env::var("IPROUT_API_KEY")?)
    .send().await?
    .error_for_status()?;
let data: IpInfo = response.json().await?;

How do I look up the caller instead?

Keep the headers and error handling unchanged, but request https://api.iprout.com/ip with no address after /ip.

What does production code need?

Keep the key server-side, use a finite timeout, inspect HTTP status before decoding success data, and handle 401, 422, 429, and transient 500 responses.

  • Read IPROUT_API_KEY from a secret environment
  • Do not retry 401 or 422 automatically
  • Use bounded backoff for transient server or network failures
