🚀 Quick Start

Add to your Cargo.toml:

[dependencies]

hermes-sdk = "0.1"

tokio = { version = "1.0", features = ["full"] }

Basic Usage

use hermes_sdk::{EbayClient, EbayConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Configure eBay client
    let config = EbayConfig::new()
        .with_app_id("your-app-id")
        .with_cert_id("your-cert-id")
        .with_sandbox(true); // Use false for production
    
    let mut client = EbayClient::new(config)?;
    
    // Search for items
    let results = client.search_items("gaming laptop", Some(10)).await?;
    println!("Found {} items", results.total);
    
    // Get item details
    let item = client.get_item("item-id").await?;
    println!("Item: {}", item.title);
    
    // Access specialized clients
    let analytics = client.analytics()?;
    let inventory = client.inventory()?;
    let compliance = client.compliance()?;
    
    Ok(())
}

Environment Variables

Create a .env file:

EBAY_APP_ID_SANDBOX=your-sandbox-app-id
EBAY_CERT_ID_SANDBOX=your-sandbox-cert-id
EBAY_DEV_ID_SANDBOX=your-sandbox-dev-id
EBAY_APP_ID_PRODUCTION=your-production-app-id
EBAY_CERT_ID_PRODUCTION=your-production-cert-id
EBAY_DEV_ID_PRODUCTION=your-production-dev-id
EBAY_SANDBOX=true

Then load in your code:

use hermes_sdk::{EbayClient, EbayConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Load environment variables
    dotenvy::dotenv().ok();
    
    let sandbox = std::env::var("EBAY_SANDBOX")
        .unwrap_or_else(|_| "true".to_string())
        .parse::<bool>()
        .unwrap_or(true);
    
    let (app_id, cert_id) = if sandbox {
        (
            std::env::var("EBAY_APP_ID_SANDBOX")?,
            std::env::var("EBAY_CERT_ID_SANDBOX")?,
        )
    } else {
        (
            std::env::var("EBAY_APP_ID_PRODUCTION")?,
            std::env::var("EBAY_CERT_ID_PRODUCTION")?,
        )
    };
    
    let config = EbayConfig::new()
        .with_app_id(&app_id)
        .with_cert_id(&cert_id)
        .with_sandbox(sandbox);
    
    let mut client = EbayClient::new(config)?;
    
    // Your code here...
    
    Ok(())
}

📋 Specialized Clients

Analytics API

let analytics = client.analytics()?;
let reports = analytics.get_traffic_reports("EBAY_US", Some("2024-01-01"), Some("2024-01-31")).await?;

Inventory API

let inventory = client.inventory()?;
let offers = inventory.get_offers(Some("PUBLISHED"), Some(50), Some(0)).await?;
