For Agents
Programmatically create a user, list users. Covers 156 operations with apiKey, oauth2 authentication.
Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Zengine REST 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%2Fzengine.com%2Fzengine" | shStep 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%2Fzengine.com%2Fzengine" | 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.
What an agent can do with Zengine REST API.
Create a user
List users
Get a user
Update a user
GET STARTED
Use for: I need to a user, I want to users, Search for a user, Find all a user
Not supported: Does not handle payments, communications, or crm - use for productivity only.
Zengine is a platform for managing data through workspaces, forms, records, tasks, events, notes, files, and more. The REST API enables integration with other apps such as email systems, marketing automation systems, or EMRs. All API communications require HTTPS. Each access token is allowed 250 queries per 5 minute window. The API exposes 156 endpoints secured with apiKey, oauth2 authentication.
Delete a user
Patterns agents use Zengine REST API for, with concrete tasks.
★ Productivity Operations
Use the Zengine REST API to perform productivity operations programmatically. The API provides 156 endpoints covering core functionality including create a user, list users, get a user.
Call POST /users to create a user
Automated Users Management
Automate users operations by combining multiple Zengine REST API endpoints. Agents can list users and then get a user in a single workflow.
Call GET /users to list users, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Zengine REST 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, oauth2 tokens manually.
Search Jentic for 'create a user', load the operation schema, and execute with Jentic-managed credentials

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Zengine REST API by hand means choosing between its OAuth flow and an access_token query key, working through user and authorization paths on api.zenginehq.com/v1, and coding request handling yourself. Through Jentic you install once, import Zengine REST from the API Directory, store the credential once, and your agent calls it.
Permission scoping
The Zengine REST API puts the user and authorization ids in the URL path (/users/{userId}/authorizations/{authorizationId}), so a rule can pin your agent to one user. You choose the operations it may call, so deleting a user or revoking an authorization is not included unless you add it.
Credential isolation
Your Zengine credential 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 user' or 'list a user's authorizations', and Jentic returns the matching Zengine REST operation with its input schema so the agent calls the right endpoint without browsing the reference docs.
Alternatives and complements available in the Jentic catalogue.
Specific to using Zengine REST API through Jentic.
What authentication does the Zengine REST API use?
The Zengine REST API uses apiKey, oauth2 authentication. 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 create a user with the Zengine REST API?
Yes. Use the POST /users endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Zengine REST 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 create a user through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'create a user'. Jentic returns the matching Zengine REST API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Zengine REST API have?
The Zengine REST API exposes 156 endpoints covering users, user authorizations, user clients operations.
Can I limit what my agent is allowed to do with the Zengine REST API?
Yes. Because you run Jentic One yourself, your own rules decide which Zengine REST operations and credentials the agent can use, so you can grant read calls like GET /users and GET /users/{userId}/authorizations while withholding destructive ones such as DELETE /users/{userId} or revoking an authorization. Since Zengine puts the user and authorization ids in the URL path (/users/{userId}/authorizations/{authorizationId}), a rule can also pin the agent to a single user. Nothing outside the operations you explicitly allow is callable, and the stored credential is injected only for those calls.
/users/{userId}/authorizations/{authorizationId}
Get an authorized client
/users/{userId}/authorizations/{authorizationId}
Revoke an authorized client
