FAQ
- Description
- On the registration form, answer yes to question 1 and no to all ten of the others and you are non-professional. Answer yes to any of those ten and you are professional. The exchanges set the test, and it decides which Massive plans you can buy.

Account
- FAQ Category
FAQ
- Description
- Yes, up to 100 active keys per account, from the keys page of your dashboard. Every key on an account shares the same subscriptions and the same limits, so a second key separates your integrations without adding capacity.
- Title
- Can I use Massive's data if I am not a US citizen?
- Account Category
Account
- Description
- Yes. Citizenship and location do not restrict access to Massive's data. What does matter is whether you use it as a non-professional or a professional, because the exchanges classify those differently and professional use needs a business licence.
- Title
- Does Massive offer any education discounts?
- Account Category
Account
- Description
- Yes. Students and faculty get a discount on individual plans, verified by a university email address. It is not applied at checkout: you have to ask us, through the chat, and we apply it to your subscription.

- Yes. Qualifying startups can get 25 percent or more off their first year, with the largest reductions going to pre-launch companies. It applies to the commercial plans and is arranged through sales.
- Title
- Does Massive offer free trials?
- Account Category
Account
- Description
- Business evaluations and proofs of concept are arranged with our sales team. Individual plans have no trial, but they are billed monthly and cancelling keeps your access to the end of the month you paid for, so one month is the smallest commitment.
- Title
- How can I change my Massive email or password?
- Account Category
Account
- Description
- Both are self-serve. Change your email in the account section of the dashboard and verify the new address; reset your password with the forgot-password link on the sign-in page. Business accounts need us to do it, and a Google sign-in address is managed by Google rather than by us.
- Title
- How do I downgrade or cancel my Massive subscription?
- Account Category
Account
- Description
- Change a plan or cancel one product at a time on the subscriptions page of your dashboard, or cancel every paid product at once on the billing page; either way you keep your current access until the end of the billing period you have already paid for.
- Title
- How can I upgrade my Massive account?
- Account Category
Account
- Description
- Upgrade on the subscriptions page of your dashboard, and note that a subscription covers one asset class only. Real-time data also needs the exchange agreements signed, which is a separate step and a common reason an upgrade looks like it did not work.

FAQ
- Description
- End-of-day data works the moment you sign up and get a key, with no wait. Real-time data needs the paid tier for that asset class and the exchange agreements signed in your dashboard, which is a separate step from paying.

WebSockets
- Description
- Your API key is valid but its plan does not cover the data you asked for. Massive entitles a key per product and per tier, so find which product the request belongs to, compare it with your dashboard, and either subscribe to that product or change the request.
