\*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to support@usefulapi.io.
Pro covers this server only. Subscribe with rex_upgrade (it returns a Stripe Checkout link). Cancel any time with rex_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running rex_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Use a dedicated agency-invited integration user with only the privileges needed. It may consume a paid agency seat. Rex Verified Integrator status covers seat-fee benefits and sandbox eligibility; this connection uses the documented ordinary live-account integration flow. Choose Australia/New Zealand or the UK and, if needed, an account id. Vendor charges are separate.
Credentials are encrypted. Requested contacts, property and tenancy details, notes and tasks reach the connected AI client and its LLM provider. Connect only records you are authorized to process there. Disconnect UsefulAPI to stop its connection. Password changes stop new sign-ins; issued tokens may remain valid until vendor expiry/revocation. We request one-hour tokens, but API activity can extend them. Billing follows Rex user id and region across that user's accounts.
Only three writes are exposed: create a person contact, an internal note or a reminder. They require a positive created id to report success. No operation is automatically replayed; check Rex before repeating an uncertain create. Notes/reminders may be visible to agency colleagues and interact with configured workflows. No message-send API is exposed. Reminder completion remains unavailable pending a verified success response.
All 33 tools were checked against current vendor documentation and local mocks. No real customer reads or business writes were tested.
