No. This package is deprecated and frozen as of 1.4.2. Install tardis-dev instead, which is the active replacement. tardis-client exists only to point users to the migration path; no new features or maintenance will be added. If you are already using it, follow the migration guide in the package description.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later; async/await runtime needed.
- Package is frozen and will not receive updates.
- Low install friction with three lightweight async dependencies (aiohttp, aiofiles, sortedcontainers).

What it is and what it does
tardis-client was a Python async client for replaying historical tick-level cryptocurrency market data from the tardis.dev API. It provided methods to stream trades, orderbook snapshots, and other market events from multiple exchanges (BitMEX, Deribit, etc.) within a specified date range, along with local cache management. The package depended on aiohttp for HTTP requests, aiofiles for async file I/O, and sortedcontainers for efficient data structures.
As of version 1.4.2 (released 2026-03-26), tardis-client is deprecated and frozen. The package no longer receives new features or maintenance. Its sole purpose now is to direct existing users to tardis-dev, the unified replacement that consolidates replay, dataset downloads, exchange metadata, and cache helpers into a single package. The description includes migration examples showing how to port replay and cache-clearing code to the new API.
Use it for
- Backtest trading strategies using historical cryptocurrency market data from multiple exchanges.
- Analyze historical orderbook and trade data for market microstructure research.
- Replay market events for debugging or validating trading algorithms offline.
