Questions

Where do the figures come from?

From public sources: company announcements, SEC filings and press reports. Each figure has its date and a link to the source. Valuations are reported figures, not market prices.

How do the packages work?

There are four packages that include one another: Free, Professional, Business and Enterprise. Each one has everything of the previous one with higher limits. Paid packages are charged by card on Stripe from the first day, monthly or yearly (10 months for 12), with an automatic invoice. Beyond the limits the service continues at the published prices.

Can I change plan or cancel?

Yes, at any time from your dashboard: card, plan, invoices and cancellation are in the billing portal.

Is this investment advice?

No. Unicorn Data provides information only, with no recommendation to buy or sell anything.

Do I get an invoice?

Yes. Stripe issues an invoice for every payment automatically, with your company details and tax ID.

Can I try it without a card?

Yes. Free includes 1,000 API calls a month, the widget and a webhook, plus $50 of welcome credit for usage beyond the limits (for company accounts, once per email domain; valid for 90 days). The card is asked only when usage passes the welcome credit.
