* [Pro](#what-are-the-differences-between-subscription-types)
* [Business](#what-are-the-differences-between-subscription-types)
2. Proceed to checkout where you provide your email address and payment details. [See accepted payment methods](https://paddle.com/support/which-payment-methods-do-you-support/).
* accepted payment methods
* Credit Cards (Mastercard Visa Maestro American Express Discover Diners Club JCB UnionPay)
* PayPal
3. Successfully complete your payment and receive the API key via email that allows you to [download CSV datasets](https://docs.tardis.dev/downloadable-csv-files/overview) and [access historical data via API](https://docs.tardis.dev/api/quickstart). API key is valid as long as subscription is active.
{% hint style="info" %}
For larger orders we also accept [pay through invoicing](#can-i-pay-through-invoicing).
{% endhint %}
Do you provide discounts?
We provide discounts in a transparent form via [different subscription types](#what-are-the-differences-between-subscription-types).
How does subscription-based access work?
The subscription-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](https://docs.tardis.dev/data#what-is-the-historical-market-data-delay-in-relation-to-real-time), as well as [existing historical market data](#do-subscriptions-include-access-to-historical-data-as-well), the range of which depends on the chosen billing period.
There are three 'dimensions' you can customize your subscription by:
* Subscription type - [Academic, Solo, Pro, or Business](#what-are-the-differences-between-subscription-types)
* Data plan (which exchanges data you get access to) - [Perpetuals](#what-is-included-in-perpetuals-data-plan), [Options](#what-is-included-in-options-data-plan), [Spot](#what-is-included-in-spot-data-plan), [Derivatives](#what-is-included-in-derivatives-data-plan) or [All Exchanges](#what-is-included-in-all-exchanges-data-plan)
* Billing interval (how much of historical data you get access to) - [monthly, quarterly or yearly](#do-subscriptions-include-access-to-historical-data-as-well)
For example "[All Exchanges](#what-is-included-in-all-exchanges-data-plan)" Business Subscription with [yearly billing period](#do-subscriptions-include-access-to-historical-data-as-well) allows accessing **all available existing historical data via API and CSV files** and **one year of new data** as it becomes available (for initial payment).
Your API key is valid as long as the subscription is active and provides access to [**all available data types**](https://docs.tardis.dev/data#what-data-types-do-you-support) (trades, order book data, quotes, funding, liquidations, etc.) for the exchanges included in your data plan. The access scope depends on your subscription type:
* **Academic and Solo** — [downloadable CSV files](https://docs.tardis.dev/downloadable-csv-files/overview) only
* **Pro and Business** — [downloadable CSV files](https://docs.tardis.dev/downloadable-csv-files/overview), [raw data replay API](https://docs.tardis.dev/api/quickstart), [tardis-machine](https://docs.tardis.dev/tardis-machine/quickstart), and [instruments metadata API](https://docs.tardis.dev/api/instruments-metadata-api)
What are the differences between subscription types?

{% hint style="info" %}
**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 priority email support with 8-12 business hours initial response time.
**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 provide dedicated code snippets to help with integration.
{% endhint %}
{% hint style="info" %}
Academic subscriptions require confirmation of eligibility, for example using university (@edu) email address.
{% endhint %}
{% hint style="info" %}
**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 (IP addresses) at the same time. [Real-time market data streaming](https://docs.tardis.dev/general#do-you-support-consolidated-real-time-market-data-streaming) feature does not have this limitation (it does not require an API key).
{% endhint %}
Do subscriptions include access to historical data as well?
Yes, **depending on chosen billing period**, subscriptions include access to existing historical market data as well:
* **Yearly billing:**
* **Business subscriptions:** access to **all available historical data** since **2019-03-30** for majority of the supported exchanges ([see exchange details page](https://docs.tardis.dev/historical-data-details/overview#per-exchange-historical-data-details) for exact date for particular exchange)
* **Academic, Solo, and Pro subscriptions:** access to **4 years of historical data**, e.g., subscription that has started at 2026-01-01 includes access to historical data since 2022-01-01
* **Quarterly billing:** access to **12 months of historical data**, e.g., subscription that has started at 2026-01-01 includes access to historical data since 2025-01-01
* **Monthly billing:** access to **4 months of historical data**, e.g., subscription that has started at 2026-01-01 includes access to historical data since 2025-09-01
Historical data access is not a rolling time window, but a fixed starting date since when historical data is available for your subscription.
