Unlocking multi-source compliance checks
“My current LimitGuard key doesn't have access to all the data sources yet — please upgrade it to Starter so I can run full 8-source risk scores on the businesses I'm onboarding.”
Enabling paid tier after trial
“I've been testing LimitGuard and I'm ready to go live — upgrade my API key to the Starter plan so I can use trust scoring in production for my agent economy platform.”
