The Twilio SendGrid Marketing Campaigns Contacts API allows you to manage all of your marketing contacts programmatically. You can also import and export contacts using this API. The Contacts API allows you to associate contacts with lists and segments; however, to manage the lists and segments themselves, see the [Lists API](https://docs.sendgrid.com/api-reference/lists/) and [Segments API](https. The API exposes 15 endpoints secured with bearer authentication.
Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Twilio SendGrid Marketing Campaigns Contacts API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.
Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | shStep 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
