deribit-http 0.7.0

Deribit HTTP Client (deribit_http)

Production-ready asynchronous HTTP client for the Deribit API v2. Version 0.6.0 provides ~95% coverage of all HTTP-compatible Deribit endpoints.

Designed for server integrations, batch jobs, and tooling that prefer REST/HTTP over WebSocket. Built on reqwest and tokio, with full WASM/Cloudflare Workers support.

Key features

• 100+ endpoints implemented across public and private APIs
• Pure async HTTP with reqwest + tokio (native) or fetch (WASM)
• Cross-platform: Native, WASM browsers, and Cloudflare Workers
• OAuth2 authentication with automatic token renewal
• Token-bucket rate limiting per endpoint category
• 40+ strongly-typed models with Serde serialization
• 126 unit tests ensuring reliability

Installation

Add to your Cargo.toml:

[dependencies]
deribit-http = "0.6"
tokio = { version = "1", features = ["full"] }

Quick start

use deribit_http::DeribitHttpClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // true = testnet, false = mainnet
    let client = DeribitHttpClient::new();

    // Public calls (no authentication required)
    let currencies = client.get_currencies().await?;
    println!("Supports {} currencies", currencies.len());

    // Example: ticker
    let ticker = client.get_ticker("BTC-PERPETUAL").await?;
    println!("Mark price: {}", ticker.mark_price);

    Ok(())
}

Authentication and private endpoints

• OAuth2 (Client Credentials): DeribitHttpClient::authenticate_oauth2(client_id, client_secret) returns an AuthToken and keeps it in the AuthManager.
• Helpers: is_authenticated(), get_auth_token().
• Session management: exchange_token(refresh_token, subject_id, scope) and fork_token(refresh_token, session_name, scope).
• API Key: the authenticate_api_key method exists but is currently not implemented and will return an error.

Configuration

• Environment shortcut: DeribitHttpClient::new() for Testnet and new(false) for Production.
• Custom configuration: DeribitHttpClient::with_config(HttpConfig) lets you set base_url, timeout, user_agent, testnet, and optional credentials.
• Validation: configuration is validated on client creation.

Project structure (modules)

• auth: AuthManager (OAuth2, token management) and related types (e.g. AuthRequest).
• client: DeribitHttpClient, public/private methods, auth helpers, exchange_token and fork_token.
• config: HttpConfig and environment helpers (testnet/production) and headers/base_url.
• connection and session: infrastructure support types (shared across the ecosystem).
• endpoints: HTTP implementation of public and private methods (see coverage below).
• error: HttpError variants such as NetworkError, RequestFailed, InvalidResponse, AuthenticationFailed, ConfigError.
• message and model: HTTP types (ApiResponse, ApiError, AuthToken, etc.).
• rate_limit: RateLimiter and categorize_endpoint with per-category limits.
• constants: base URLs (production/testnet), endpoint routes, and common headers.

Public endpoints (30+)

Private endpoints (70+)

Require valid authentication (OAuth2):

Limitations and important notes

• This crate does not implement WebSocket or streaming. Some Deribit endpoints exist only over WS (for example, /public/hello and /private/logout) and are not available in this HTTP client.
• API Key authentication: the authenticate_api_key stub exists but is not yet implemented in the HTTP client.
• Deribit uses JSON-RPC over HTTP; this client exposes ergonomic methods that build URLs with query params and parse ApiResponse<T> in a strongly-typed manner.

Error handling

The HttpError type centralizes common failures: network issues (NetworkError), non-success HTTP responses (RequestFailed), parsing/structure errors (InvalidResponse), authentication failures (AuthenticationFailed), and configuration conditions (ConfigError).

Rate limiting

The RateLimiter categorizes each URL and applies a token-bucket scheme per category (Trading, MarketData, Account, Auth, General). You can inspect it via rate_limiter().

Examples

See the examples/ directory for comprehensive examples:

• Public examples (16 binaries): Market data, instruments, trades, funding, settlements
• Private examples (7 binaries): Trading, orders, positions, account management, mass quotes

# Run a public example
cargo run --bin check_currencies

# Run a private example (requires .env with credentials)
cargo run --bin trading_endpoints
