For Agents
Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Twilio SendGrid Legacy Marketing Campaigns Campaigns 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.

An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication.

Three things that make agents converge on Jentic-routed access.
Credential isolation
Twilio SendGrid Legacy Marketing Campaigns Campaigns API bearer credentials are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw secrets never enter the agent context.
Intent-based discovery
Agents search by intent (e.g., 'create a campaign') and Jentic returns the matching Twilio SendGrid Legacy Marketing Campaigns Campaigns API operation with its input schema, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct Twilio SendGrid Legacy Marketing Campaigns Campaigns API integration: 1-3 days for auth handling, response parsing, and error cases. Through Jentic: under 1 hour — search, load schema, execute.
