FAQ
Q: How do I query what data are available?
A: All available data can be queried by lakeapi.list_data function (https://lake-api.readthedocs.io/en/latest/lakeapi.html#lakeapi.main.list_data) or by reading contents.json.bz2 file in data type directory on s3. (eg .../trades/contents.json.bz2).
Q: Do you offer a trial period?
A: We have a small free dataset, which should be enough for evaluation, but we don’t offer any trial period.
Q: Do you offer discounts?
A: We offer a 20% discount for the first 6 months for all new subscribers on For Individuals plans. We can discuss individual discounts for the For Companies plan based on company size and intended usage of our data, but not for the For Individuals plan. There is no special discount for students.
Q: Do you have real-time data or data from today
A: We don’t offer real-time data, only historical. The data are uploaded to our servers around 3 AM UTC the next day.
Q: Will 300 GB of data (For individuals plan monthly data limit) be enough for my use case? How much data can I expect?
A: 300 GB = approx. 80 years of level_1 data or 10 years of book data or 30 years of trade data on BTC-USDT. If you’ll need more, you’ll be asked to pay quarterly or pay extra charge for increasing the data limit.
Q: How do I cancel my subscription?
A: You can cancel your subscription at any time by clicking the Manage subscription button on our front page.
Q: Can I access S3 data directly without Python/lakeapi?
A: Yes, but it is not recommended/supported. More details.
Q: Discount is not showing up on Stripe page, why?
A: This can happen if you use a Javascript blocker browser extension or have JS disabled in your browser. Also you have to wait for around 3 seconds for the discount to show up.
Q: Some data are missing, can you add it?
A: Our coverage is approximately 99.7% or 98% for order book data and its derivatives (e.g. level_1). We are not able to fix missing order book data in the past.
Q: Where can I register, I only see a Stripe payment page?
A: The stripe payment page also performs the registration. No password is required. You will receive your API credentials after the payment is completed.
