🚀 Quickstart

use stanzaapi_iso20022_parser::Iso20022ParserClient;

#[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/iso20022-parser
    let client = Iso20022ParserClient::new(None, None);

    let response = client.validate("<Document xmlns=\"urn:iso:std:iso:20022:tech:xsd:pacs.008.001.08\">...</Document>").await?;

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