Billing and Subscriptions

Common questions about plans, pricing and invoices

What is the order process?

  1. Choose a data plan and subscription type in the order form.

  2. Continue to payment and sign in to your Tardis.dev account if needed. You return to your selected order and enter payment details directly on the page. Checkout uses your account email address. See accepted payment methods.

    • accepted payment methods

      • Credit Cards (Mastercard Visa Maestro American Express Discover Diners Club JCB UnionPay)

      • PayPal

  3. Successfully complete your payment and receive an email with your access details. If you already have an active API key, continue using it; otherwise, the email includes a new key. Your subscription is available in your account. The key lets you download CSV datasets and, with Pro or Business, access historical data via API. It is valid while your account has an active subscription.

For larger orders we also accept pay through invoicing.

Do you provide discounts?

No. We do not provide discounts, but we offer different subscription types for solo traders, academic users, professionals and businesses.

Do you offer one-off purchases or custom data exports?

No. Historical data is available through subscriptions; we do not sell fixed date ranges or prepare custom data exports.

How do free trials work?

To start a free trial with an agent, give it the email address you want to use for Tardis.dev and ask it to follow the Account API authorization guide. After you authorize access, the agent can set up your account, start the trial and create one Data API key.

A free trial gives you limited access to historical data. It requires no payment details and does not automatically convert into a paid subscription.

How does subscription-based access work?

Subscription-based access uses monthly, quarterly or yearly billing. An active subscription gives access to newly collected market data as it becomes available, plus existing historical market data. The historical range depends on the billing interval.

When ordering a subscription, you choose:

For example, an "All Exchanges" Business subscription with yearly billing gives access to all available existing historical data via API and CSV files, plus new data as it becomes available during the yearly billing interval.

The product access scope depends on your subscription type:

What are the differences between subscription types?

Academic subscriptions are available with quarterly or yearly billing and require confirmation of eligibility, for example using a university email address.
