kraken-api-client

kraken-api-client is an async Rust library for Kraken Spot and Futures APIs.

It includes REST clients, WebSocket clients, auth helpers, typed request/response models, and optional rate-limiting wrappers.

• Spot REST client for public and private endpoints.
• Spot WebSocket v2 client for market data and trading channels.
• Futures REST and WebSocket clients.
• Typed models for requests and responses.
• Auth support for signatures, credentials providers, and nonce generation.
• Rate limiting utilities for public, private, and trading flows.

Usage

use kraken_api_client::spot::rest::SpotRestClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = SpotRestClient::new();
    let time = client.get_server_time().await?;
    println!("Server time: {:?}", time);
    Ok(())
}

Credentials

Private endpoints use credentials from your own source.

You can use StaticCredentials or EnvCredentials.

Expected env vars are KRAKEN_API_KEY and KRAKEN_API_SECRET.
