🚀 Quickstart

use stanzaapi_pharma_dscsa::PharmaDscsaClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Reads STANZA_API_KEY from environment automatically
    // Public edge default: https://api.stanzaapi.com/pharma-dscsa
    let client = PharmaDscsaClient::new(None, None);

    let response = client.validate("(01)00300012345678(21)100000000001(17)261231(10)LOT12345").await?;

    if response.success {
        println!("Verification Success: {:?}", response.data);
    } else {
        eprintln!("Validation Error: {:?}", response.error);
    }

    Ok(())
}
