Installation

[dependencies]
defillama = "0.1"
tokio = { version = "1", features = ["full"] }

Quick Start

use defillama::Client;

#[tokio::main]
async fn main() -> Result<(), defillama::Error> {
    // Create a free-tier client
    let client = Client::new()?;

    // Get all protocols
    let protocols = client.tvl().protocols().await?;
    println!("Found {} protocols", protocols.len());

    // Get current ETH price
    use defillama::coins::Token;
    let tokens = vec![Token::coingecko("ethereum")];
    let prices = client.coins().current(&tokens).await?;

    Ok(())
}

Pro API Access

Some endpoints require a Pro API key. Get one at defillama.com/subscription.

// Create client with Pro API key
let client = Client::with_api_key("your-api-key")?;

// Or from environment variable
let client = Client::from_env()?; // reads DEFILLAMA_API_KEY

// Access Pro endpoints
let yields = client.yields().pools().await?;

Environment Variables

• DEFILLAMA_API_KEY - Your DefiLlama Pro API key (optional, for Pro endpoints)
