Your key to the whole dataset
An API key is a personal access code. It lets you export predicate tables from the site, call the REST API from your own tools, and connect AI assistants through our MCP server - all metered to your key, no account needed.
What free includes
1,000 API calls a month, 3 predicate-table exports a month, unlimited shareable reports, and full MCP access. No credit card, no expiry.
What happens when you click
We mint a key instantly and show it once on the next page - copy it somewhere safe. It also drops into a browser cookie so exports just work.
When you outgrow it
Pro removes the export cap and adds weekly change alerts. Upgrading later keeps the same key. Compare plans.
Is this really free?
Yes. The free tier is how consultants evaluate Atlas before subscribing; most predicate-research sessions fit inside it. We publish all prices - see pricing.
What if I lose my key?
Generate a new one with the same button - free keys are disposable. Paid keys arrive after checkout and can be recovered from your Stripe receipt page.
