Anything else, .
A free account covers most of the Signal8 web app. Pro adds everything on this page, including the developer API and the hosted MCP server, which are not part of the free account.
Yes. Pro is a Stripe subscription. Cancel from your account and billing stops at the end of the period you have already paid for; you keep access until then. Cancelling during a free trial means you are not charged at all.
No. Signal8 is not a registered investment adviser or broker-dealer. Everything on the platform is information read from public filings and market data, provided for your own research. It is not a recommendation to buy, sell or hold any security.
