## The 78 GTM tools a solo operator can call for free

Free to start means a solo operator can get API access without talking to anyone. It does not mean unlimited, it does not mean free forever, and this directory does not track prices or quota sizes, so nothing here should be read as a pricing claim. It tracks one thing: whether the door opens without a sales call.
