Billing and Subscriptions

What is the order process?

  1. Select data plan and access type that you're interested in via order form on Tardis.dev website.

  3. Successfully complete your payment and receive the API key via email that allows you to download CSV datasets and access historical data via API.

Do you provide discounts?

We do provide discounts in a transparent way via indie subscriptions. Indie plans are discounted up to 50% in comparison to analogous business subscriptions plans.

For students and academic researchers we offer up to 70% discounts for all indie subscriptions. Contact us from your university email and we'll get back to you with discount code.

Can I pay through invoicing?

Yes, we offer invoicing for customers paying over $2000 for data access. Contact us and we'll get back to you as soon as possible with more information.

Do you accept payments in cryptocurrency?

Yes, we accept BTC, ETH and USDT for one-off purchases. Contact us and we'll get back to you as soon as possible with details.

How one-off purchase based access works?

One-off purchase provides access to specific time periods of historical market data. API key is valid for a year since purchase and allows access to all available data types (trades, order books etc) for ordered date ranges.

How subscription based access works?

Subscription provides access to market data as it becomes available. API key is valid as long as subscription is active and allows access to all available data types both via API and downloadable CSV files. All subscriptions include access to historical market data which range depends on chosen billing period.

What is the difference between Indie and Business subscriptions?

Indie subscriptions plans are specifically designed for indie quants, startups and prop shops that are just getting started and offer heavily discounted pricing. Both email based support and limited integration assistance are included.

Indie subscriptions plans include single API key that can be used to get access to historical data. Such API key can't be used by many team members at the same time. Real-time market data streaming does not have such limitations (does not require API key at all).

Business subscriptions plans are designed for companies that require dedicated integration assistance and high priority professional support - we do provide dedicated communication channel (via Telegram Messenger) for your company where our team is on standby to answer any questions you may have.

Business subscriptions plans include up to 10 additional API keys that can be used to get access to historical data by many team members at the same time including across different geo-locations.

In addition we also offer custom features development and exchanges APIs peculiarities consulting based on our existing experience when working with exchanges' APIs. Contact us if you're interested.

  • all available historical data if subscription is billed yearly - historical market data is available since 2019-03-30 for majority of the supported exchanges (see exchange details page for exact date for particular exchange)

  • 8 months of historical data if subscription is billed quarterly, e.g., subscription that has started at 2020-04-01, includes access to historical data since 2019-08-01 - it's not a rolling time window, but fixed starting date since when historical data is available for your subscription

  • 4 months of historical data if subscription is billed monthly, e.g., subscription that has started at 2020-04-01, includes access to historical data since 2019-12-01 - it's not a rolling time window, but fixed starting date since when historical data is available for your subscription
