Use Tardis.dev data for backtesting with your AI coding agent.
Super Algo Kit can use Tardis.dev data for backtesting crypto bots that your own AI coding agent builds. Tardis.dev sells tick-level history from many exchanges: order-book snapshots and updates, trades, funding, open interest and liquidations. The kit replays it in cost-aware backtests, then pairs it with an exchange card such as Binance or Bybit for the paper run. Tardis.dev itself places no orders.

Paper first
A Tardis.dev bot, built paper first.
Super Algo Kit runs inside the coding agent you already use. It interviews you, writes the spec with pass marks set first, then builds, backtests and paper-tests. Real money starts only when you type the authorize command.
The plan, step by step
Tick them off as you go.
How Tardis.dev access and data delivery work
You create an account, subscribe and get an API key from the account. Without a key, only the first day of each month of history is available (reported). Academic, Solo and Professional plans get 1 active key tied to 1 source IP; Business plans allow up to 10 keys (reported).
Data comes as exchange-native messages or in a normalised format shared across exchanges. The Python client covers replay and CSV downloads in native format only. For normalised replay or live streaming, use the Node.js client or the local tardis-machine server.
What Super Algo Kit does with Tardis.dev data for backtesting
The kit uses replay for backtests and keeps the raw messages before normalising them. It rebuilds order books and checks that every update fits the last book state, because gaps and later corrections are not documented. The time Tardis received each message is kept apart from the exchange's own event time.
Backtests and paper runs built on replay are labelled simulated or historical, with the data source named. Pass marks are set before the first test, costs are included, and every parameter change is logged as a trial.
Paper trading with Tardis.dev: what a data feed can do
Tardis.dev cannot place, change or cancel orders, and there is no trial beyond the free first day of each month (reported). Live streaming through the Node.js client is reported to connect straight to the exchanges' public feeds without a Tardis key.
For the paper run, the kit pairs the feed with an exchange card from the crypto pack, such as Binance, Bybit or OKX. That run uses the exchange's test environment or the kit's own paper broker on live data.
Tardis.dev limits and costs to plan for
Limits are per account, not per key (reported). Solo and Professional plans allow 3,000 requests a minute and 20 TB of compressed transfer a month; Business allows 9,000 requests a minute. Official clients call the API in parallel, so a few replay sessions together can use up the budget fast.
Prices and the display, redistribution and commercial-use terms were not confirmed. So the kit forbids redistributing stored data until you confirm the terms with the vendor. It caps itself at 1,800 requests a minute, runs one replay session at a time and backs off on any refusal, a kit judgement.
Before you rely on it
Gotchas to plan for.
- Non-Business plans allow 1 key on 1 source IP, so a laptop plus a server breaks the setup (reported).
- Parallel replays multiply calls: 3 replay workers can exhaust 3,000 requests a minute (reported).
- The Node.js client needs Node.js 24.19 or later, and the Python client needs Python 3.10 or later.
- The Python client has no normalised replay and no live streaming.
- Map symbols by venue, underlying, expiry and kind, never by symbol text alone.
- Coverage and start dates differ per exchange; read the exchange list before choosing a venue (reported).
FAQ
Tardis.dev: questions.
What Tardis.dev data can I use for backtesting?
Tardis.dev sells tick-level crypto data: order-book snapshots and updates, trades, funding, open interest, index and mark prices, and liquidations. History starts on 30 March 2019 for most exchanges (reported). Super Algo Kit replays it in cost-aware backtests with pass marks set first.
Can I paper trade with Tardis.dev?
Not on its own, because a data feed cannot place orders. Super Algo Kit pairs it with an exchange card such as Binance or Bybit. The paper stage runs on that exchange's test environment or the kit's own paper broker. Live trading waits until you type the authorize command.
Is Super Algo Kit affiliated with Tardis.dev?
No. Super Algo Kit is not affiliated with or endorsed by Tardis.dev. The name is used only to say the kit works with its data.
Is there a free Tardis.dev tier?
There is no free trial tier beyond the first day of each month, which works without an API key (reported). Other history needs a subscription, and prices were not confirmed by the kit.
Can I share my Tardis.dev key or data?
Whether a key may serve an app used by other people was not confirmed, so do not share a key across users. Redistribution terms were not confirmed either, and the kit forbids redistributing stored vendor data until you confirm them.
