StockMarketStack FAQ
What does “hands-on” mean on a card?+
It means the reviewers obtained a key or account and actually used the tool to verify its limits and documentation.
How often is a card updated?+
Each block on a card has its own verification date and is refreshed independently, not on a site-wide schedule.
Can an AI agent read these pages?+
Yes – every card has a plain-Markdown twin accessible by adding .md to the URL.
What is not included in the catalogue?+
Brokers, robo-advisors and signal services are excluded; only software and data products are listed.
Does paid placement affect card content?+
No – sponsorship only adds a label; the tool’s data, pricing and fields remain unchanged.
