### Initializing Blockfrost API and Fetching Genesis Data

Source: https://github.com/jpg-store/blockfrost-rust/blob/master/README.md

Demonstrates how to create a `BlockfrostAPI` instance using an API key and fetch the blockchain's genesis information asynchronously using `tokio`. Requires the `tokio` runtime.

```Rust
use blockfrost::{BlockfrostAPI, BlockfrostResult};

fn build_api() -> BlockfrostResult<BlockfrostAPI> {
    let api = BlockfrostAPI::new("mainnetxvMK4xOpp5mHJgihi055KDLU64JJv2be", Default::default());
    Ok(api)
}

#[tokio::main]
async fn main() -> blockfrost::BlockfrostResult<()> {
    let api = build_api()?;
    let genesis = api.genesis().await?;

    println!("{:#?}", genesis);
    Ok(())
}
```

### Adding blockfrost-rust Dependency

Source: https://github.com/jpg-store/blockfrost-rust/blob/master/README.md

Adds the `blockfrost` crate as a dependency to your Rust project's `Cargo.toml` file, specifying version 1.0.1.

```TOML
blockfrost = "1.0.1"
```
