Clear Street Rust SDK

Rust library providing an API interface to the public endpoints offered by Clear Street.

NOTE

This is a very rough work in progress. It is incomplete, mising features with shortcuts taken. Feel free to open a PR. The sqlx mappings to work with orms should be behind a feature, enum mappings and safety added and all that.

Features

• Fully asynchronous Rust client based on reqwest.
• Typed models for Clear Street public API requests and responses.
• Ready-to-integrate into trading systems, research tools, or financial applications.
• Minimal external dependencies for high performance.

Installation

Add the SDK to your Cargo.toml:

[dependencies]
clearstreet_sdk = { git = "https://github.com/YOUR_USERNAME/clearstreet-rust-sdk.git", branch = "main" }

use clearstreet_sdk::ClearStreetClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize the client
    let client = ClearStreetClient::new();

    // Fetch market data for a symbol
    let market_data = client.get_market_data("AAPL").await?;

    println!("{:?}", market_data);

    Ok(())
}

Roadmap

• Implement authenticated/private endpoints

• Add support for WebSocket streaming (if provided by Clear Street)

• Improve error handling and expose structured API errors

• Full test coverage

• Publish as an open-source crate
