How to Make Async HTTP Requests with reqwest

Use the reqwest crate with async/await to make non-blocking HTTP requests. Add reqwest to your Cargo.toml and call reqwest::get() inside an async function, then .await the response and its body.

use reqwest;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let response = reqwest::get("https://www.rust-lang.org").await?;
    let body = response.text().await?;
    println!("{body}");
    Ok(())
}

[dependencies]
reqwest = { version = "0.12", features = ["json"] }
tokio = { version = "1", features = ["full"] }

Making async HTTP requests with reqwest lets your program ask a website for data without freezing while it waits for an answer. It works like ordering food at a busy restaurant: you place your order and go do other things until the food is ready, rather than standing at the counter staring at the kitchen. You use this pattern when building apps that need to fetch data from multiple sources quickly.
