Install Jentic One Beta
Connect the Zenlist Partner Integration API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Zenlist Partner Integration 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Fzenlist.com%2Fzenlist-partner-integration-api" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fzenlist.com%2Fzenlist-partner-integration-api" | 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.

AI Agent Integration via Jentic
AI agents discover and call Zenlist Partner Integration API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle apiKey tokens manually.
Search Jentic for 'subscribe to a webhook', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Zenlist Partner Integration API by hand means setting its x-api-key header on every request, working through subscription and agent paths on openapi.zenlist.com/v2, and coding cursor paging yourself. Through Jentic you install once, import Zenlist Partner Integration from the API Directory, store the key once, and your agent calls it.
Permission scoping
Zenlist puts the subscription and agent ids in the URL path (/subscriptions/{subscriptionId} and /agents/{agentId}), so a rule can pin your agent to one subscription or one agent record. You choose the operations it may call, so deleting a subscription is not included unless you add it.
Credential isolation
Your Zenlist key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'create a webhook subscription' or 'look up an agent', and Jentic returns the matching Zenlist Partner Integration operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Zenlist Partner Integration API through Jentic.
What authentication does the Zenlist Partner Integration API use?
The Zenlist Partner Integration API uses an API key passed in the `x-api-key` header. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.
Can I subscribe to a webhook with the Zenlist Partner Integration API?
Yes. Use the POST /subscriptions endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Zenlist Partner Integration API?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I subscribe to a webhook through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'subscribe to a webhook'. Jentic returns the matching Zenlist Partner Integration API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Zenlist Partner Integration API have?
The Zenlist Partner Integration API exposes 19 endpoints covering agent, chat, client operations.
Can I limit what my agent is allowed to do with the Zenlist Partner Integration API?
Yes. Because you run Jentic One yourself, your own rules decide which Zenlist operations and credentials the agent may use, so you can allow read calls like GET /subscriptions and GET /agents while withholding writes such as POST /subscriptions or DELETE /subscriptions/{subscriptionId}. Since Zenlist puts the subscription and agent IDs in the URL path, a rule can pin the agent to a single subscription or a single agent record. Deleting a subscription is only possible if you explicitly grant that operation.
