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?

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 two 'dimensions' you can customize you subscription by:

For example "Unlimited" subscription with yearly billing period allows accessing all available existing historical data 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.) both via API and downloadable CSV files.

What is the difference between Indie and Business subscriptions?

Indie subscriptions plans are 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 feature does not have this limitation (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.

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:

  • 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

All subscriptions provide access to all available data types (trades, orders book data, quotes, funding, liquidations etc.) both via API and downloadable CSV files.
