API (official)

• Base URL: https://api.zoominfo.com/gtm
• Endpoint: POST /data/v1/companies/search
• Auth: an OAuth access token, sent as Authorization: Bearer <token>
• Docs: https://docs.gtm.ai/reference/api-overview

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
