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.
    2.
    Proceed to checkout where you provide email address and payment details.
      accepted payment methods
        Credit Cards (Mastercard Visa Maestro American Express Discover Diners Club JCB UnionPay)
        PayPal
        Apple Pay (one-off purchases only)
        Wire Transfers (for one-off purchases only)
      ​
    ​
    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. API key is valid as long as subscription is active or 6 months for one-off purchases.
For larger orders we do also accept pay through invoicing. Need quotation document first?
​

Do you provide discounts?

We do provide discounts in a transparent form via different subscriptions types.
​
​

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 both via API and downloadable CSV files.
​
​

How subscription based access works?

Subscriptions based access model relies on recurring payments at regular intervals (monthly, quarterly, yearly) and offers access to newly collected market data as it becomes available as well as existing historical market data which range depends on chosen billing period.
There are three 'dimensions' you can customize you subscription by:
For example "Unlimited" Business Subscription with yearly billing period allows accessing all available existing historical data via API and CSV files for all exchanges and one year of new data as it becomes available (for initial payment). API key is valid as long as subscription is active and allows access to all available data types (trades, orders book data, quotes, funding, liquidations etc.) via downloadable CSV files and via raw market data API (for Pro and Business subscriptions types only).

Business subscriptions 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 and 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 also provide vendor onboarding support on our side including filling W9, ACH and other company specific forms as well as integration assistance - we do provide dedicated code snippets to help out with seamless integration.
Academic subscriptions require confirmation of eligibility, for example using university (@edu) email address.
Pro, academic and solo subscriptions plans include single API key that can be used to get access to historical data. Such API key can't be used by different team members at the same time. Real-time market data streaming feature does not have this limitation (does not require API key at all).
​
​

    12 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 2019-04-01 - 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
