deribridge

Async, typed Python client and middleware for the Deribit API.

deribridge is a structured layer over Deribit's WebSocket API: a typed transport client, a higher-level trading interface with order-lifecycle tracking, built-in rate limiting, and Pydantic models for every response — so you can build trading tooling without hand-parsing JSON or babysitting reconnects.

It is also the open-source bridge behind deribook, where the same Deribit data feeds real-time portfolio analytics, greeks, P&L, and risk views.

Features

• ⚡ Async-first — built on asyncio and websockets
• 🧩 Typed models — Pydantic models for orders, order books, tickers, positions, trades, account summaries, and more
• 🛡️ Thread-safe order tracking — lifecycle tracking with an internal lock and order history
• 🔁 Resilient — managed background monitoring task with cancellation + auto-restart
• 🚦 Rate limiting — built-in RateLimiter to stay within Deribit limits
• 🧪 Test & production environments — switch with a single flag
• 📊 Analytics-ready — response models that work well for portfolio dashboards, risk monitors, and tools like deribook

Installation

pip install deribridge

Until the first PyPI release you can install straight from GitHub:

pip install git+https://github.com/fracasamax/deribridge.git

Requires Python ≥ 3.12.

Development install

git clone https://github.com/fracasamax/deribridge.git
cd deribridge
uv sync        # or: pip install -e .

Configuration

Credentials are read from environment variables. configure() calls python-dotenv's load_dotenv() by default (pass load_dotenv_file=False to disable any working-directory file read). Copy the example file and fill in your Deribit API keys:

cp .env.example .env

DERIBIT_API_CLIENT_ID=your_client_id
DERIBIT_API_SECRET=your_client_secret
# Optional test-environment keys
DERIBIT_API_CLIENT_ID_TEST=your_test_client_id
DERIBIT_API_SECRET_TEST=your_test_client_secret

Quick start

import asyncio
from deribridge import DeribitAPIInterface


async def main():
    api = DeribitAPIInterface.configure(use_test_env=True)

    if await api.start_client():
        await api.subscribe_to_ticker("BTC-PERPETUAL")
        ticker = await api.get_ticker("BTC-PERPETUAL")
        print(f"BTC-PERPETUAL mark price: {ticker.mark_price}")
        await api.stop_client()


asyncio.run(main())

Fuller runnable examples live in examples/ — instrument parsing and order building (no credentials), connecting a client, and a full connect → quote → place/cancel flow (gated behind an env flag, testnet only).

Documentation

• docs/GUIDE.md — compact usage guide for developers (install, config, quick start, placing orders safely).
• docs/AI_REFERENCE.md — dense technical reference for building tooling (and for AI coding agents): full API surface, lifecycle & concurrency model, the three-outcome order contract, and known gotchas.

For a production example of the kind of analytics layer this bridge supports, see deribook.com.

Order safety: order-mutating calls (submit_order, submit_limit_order, cancel_order, replace_order) have three outcomes — success, definite failure (None), and indeterminate (IndeterminateOrderError, raised on timeout/disconnect). On indeterminate, reconcile via get_order_state / get_open_orders before retrying — never resubmit blindly. See the guides above.

Stability & compatibility

deribridge is beta (0.x): public names and return types may change between minor releases, and the high-level trading helpers in particular are still evolving. Pin a version if you need stability, and check the CHANGELOG for breaking changes.

• Targets the Deribit WebSocket JSON-RPC v2 API, with both test and production endpoints (switch via use_test_env).
• Supported on Python 3.12 and 3.13.
• Deribit may change its API at any time; tracking those changes may require updates here.
