(Crypto Facilities)

We do provide discounts in a transparent form via .

Yes, if you'd like to test the service (data quality, coverage, API performance etc.) we offer generous free trials. Simply and we'll set up trial account for you.

For we provide dedicated communication channel (via Telegram Messenger, email or Zoom calls) for your company where our team is on standby every business day (7AM - 3PM UTC) to answer any questions you may have. For and we do provide email based support with 24-48 business hours initial response time.

For there is no dedicated support provided, only self-service.

Since cryptocurrency exchanges' market data APIs are public anyone can use those to collect the data, but it's a time consuming and resource intensive undertaking (exchanges we support publish ~1000GB of new data every day), that requires investment in , constant monitoring and oversight (exchanges API changes, rate-limiting monitoring, new exchanges integrations, unexpected connection issues, latency monitoring etc.), not to mention implementation costs of data collection, storage and distribution services. All in all we think our offering is , and , provides good value and saves you time and money in comparison to in-house solution allowing you to focus on your core objective not on data management intricacies.

You can access historical market data via which provides raw data in or download with, , , , , (open interest, funding, mark price, index price) and . provide data in as well, which can be more flexible than CSV datasets for some use cases but also slower to download due to on-demand, client-side data normalization overhead in comparison to ready to download CSV files.

Any programming language that can communicate using HTTPS can communicate with our .

We do provide official and clients that offer fast and convenient access to tick-level historical market data.

Finally, our open source, locally runnable server with built-in local data caching, provides market data normalization, custom order book snapshots capabilities and real-time market data streaming support that connects directly to exchanges' WebSocket APIs. It provides both streaming HTTP and WebSocket endpoints returning market data for whole time periods (in contrast to Tardis.dev where single call returns data for single minute time period) and is available via npm and as a Docker Image.

Historical market data provided by can be accessed via HTTPS.

Locally runnable server provides both HTTP and WebSocket based APIs for accessing both historical and real-time market data.

Exchanges' market data WebSocket APIs are designed to publish real-time feeds and not historical ones. Locally runnable bridges that gap and allows "replaying" historical market data from any given past point in time with the same data format and 'subscribe' logic as real-time exchanges' APIs. In many cases existing exchanges' WebSocket clients can be used to connect to this endpoint just by changing URL, and receive market data in format for date ranges specified in URL query string params.

We do not provide hosted real-time market data API as we think that given everyone can access exchanges' APIs directly for free without restrictions, relaying on 3rd party for such crucial piece of infrastructure does not make sense (additional latency and another ). Instead we developed that offer consolidated real-time normalized market data streaming capabilities, connect directly to exchanges' WebSocket APIs and are completely free to use.

There are no API rate limits for API.

for professional level subscriptions is limited to 30 millions requests per day. For business level subscriptions there are no rate limits for raw data replay API as long as your behavior does not negatively impact other customers API usage experience. If that's the case, we'll contact your via email and do our best to help how to sort it out - in most cases it's download client bug that over and over downloads the same data in a loop.

API key can be obtained on website via . You'll receive it via email after successful order.

immediately and we will generate new API key for you.

Highly available located in in London, UK (europe-west2 region) and Tokyo, Japan (asia-northeast1 region)

We do not have a formal SLA in place yet, but all infrastructure is set up to provide highest availability possible on both data collection and distribution side with geo-redundant setup. Both data collection services and public APIs are constantly monitored from multiple locations and our team is immediately notified in case of any issue. We don't practice maintenance that would affect API availability, but in very rare circumstance if that would happen we'll communicate that in advance. If a formal SLA is something that your business require .
