Crate simple_pyth_client_rs

Pyth Price Feed API Wrapper (Rust)

A high-performance, async Rust SDK to query and stream live crypto prices using the Pyth Hermes API.

Built to provide a simpler way to interract with Pyth Hermes crypto price feeds. Search by symbols, get token prices and price streams.

✨ Features

• Fetch live and historical token prices (price + EMA)
• Stream real-time price updates
• Filter tokens by human-readable symbols
• Powered by reqwest, tokio, serde, futures

📚 Examples

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    use simple_pyth_client_rs::*;
    // Search for specific crypto/USD pairs
    let symbols = vec!["BTC", "ETH", "USDC", "SOL", "USDT"];
    let price_feeds = search_by_token_symbols(symbols).await?;
    println!("{:?}", price_feeds);
    Ok(())
}

🔧 Core Methods

• get_price_feeds() — Get metadata for all supported crypto/USD price feeds
• get_token_price_info(ids) — Get current price info for specific or all tokens
• get_live_price_stream(ids, callback) — Stream price updates and handle them with a callback
• get_price_stream_for_duration(ids, duration_secs, tx) — Stream prices for a set duration
• search_by_token_symbols(symbols) — Search and fetch prices using readable token symbols

✅ Requirements

• Rust 1.70+
• Tokio async runtime
