Who it is for
People building AI apps, home-service products, marketplaces, and insurance tools that need a real phone, a yes or no on after-hours work, a license, and a ZIP list.
AI builders
Ask for a contractor. Get a number you can stand behind.
FactRoster is where your app can look up local trade facts. One lookup stays free so apps will actually use it. You pay when you look up a lot of businesses.
Why one lookup is free
If a single lookup costs money, apps will skip it and guess. The free tier has a limit, and it only returns listings we have checked.
What you pay for
Looking up many businesses, a higher limit, and a person to call when a record looks wrong. That plan is $149/mo. Card billing is not turned on yet. The free lookups already work.
Free lookups

Higher volume
$149/mo
