The free key is not a trial: it is a real key, it does not expire and it never asks for a card. Pro exists for whoever needs volume and wants to take the database home.
One e-mail field and the key appears on screen. No card, no checkout.

With no key at all you can already query one ticker at a time: CVM accounting facts, annual indicators, multiples, dividends and REIT sheets, with a per-address limit (60 calls per hour and 150 per day, per address; AI assistants (ChatGPT, Claude, Perplexity and the MCP connector) have their own count: 2,000 per hour and 20,000 per day, per address). Nothing was taken away from the free tier to build Pro: every number stays open, company by company. Pro is for people who want the numbers outside the site (spreadsheet, code, AI), the whole database, and a person on the other side when something does not add up.
