Free developer trial for the Zamp API

Developers can test Zamp's tax engine on their own schedule, no sales call required.

Anyone with a business email can now start a free developer trial right from the Zamp API docs. Enter your email, receive a one-time code, and generate an API token on the spot.

Trial tokens connect to a dedicated sandbox company with every region configured, and trial data is cleaned up after 30 days. Sandbox tokens have their own rate limits.
