Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the CleverReach 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%2Frest.cleverreach.com%2Frest-cleverreach" | 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%2Frest.cleverreach.com%2Frest-cleverreach" | 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 CleverReach API.
Get receiver count for a client
Create a new account within an agency
Integrate CleverReach API into automated workflows
Query and filter CleverReach API records by parameters
Monitor CleverReach API operational status and events
GET STARTED
Patterns agents use CleverReach API for, with concrete tasks.
★ Marketing Operations
Use the CleverReach API to perform marketing operations programmatically. The API provides 22 endpoints covering core functionality including get receiver count for a client, get active receiver count for a client, get available mail sending quota.
Call GET /v3/clients/{id}/receivercount to get receiver count for a client
Automated Clients Management
Automate clients operations by combining multiple CleverReach API endpoints. Agents can get active receiver count for a client and then get available mail sending quota in a single workflow.
Call GET /v3/clients/{id}/activereceivercount to get active receiver count for a client, then verify the result
AI Agent Integration via Jentic
AI agents discover and call CleverReach 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 bearer tokens manually.
Search Jentic for 'get receiver count for a client', load the operation schema, and execute with Jentic-managed credentials

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the CleverReach API by hand means learning its bearer token auth, targeting the rest.cleverreach.com host, and threading client and receiver calls yourself. Through Jentic you install once, import CleverReach API from the API Directory, store the token once, and your agent calls it.
Permission scoping
CleverReach API puts the client id in the URL path (/v3/clients/{id}/...), so a rule can pin your agent to one client: it can read that client's receiver count, plan, and contingent and nothing else. You choose the operations it may call, so actions like account creation are not included unless you add them.
Credential isolation
Your CleverReach API token 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 'get the receiver count for a client' or 'validate a blacklist entry', and Jentic returns the matching CleverReach API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

Specific to using CleverReach API through Jentic.
What authentication does the CleverReach API use?
The CleverReach API uses a Bearer token in the Authorization 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 get receiver count for a client with the CleverReach API?
Yes. Use the GET /v3/clients/{id}/receivercount endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the CleverReach 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 get receiver count for a client through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'get receiver count for a client'. Jentic returns the matching CleverReach API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the CleverReach API have?
The CleverReach API exposes 22 endpoints covering clients, groups, receivers operations.
Can I limit what my agent is allowed to do with the CleverReach API?
Yes. Because you run Jentic One yourself, your own rules decide which CleverReach operations and credentials the agent may use. Since the CleverReach API carries the client id in the URL path (/v3/clients/{id}/...), you can pin the agent to a single client and allow only read calls such as receiver count, subscription plan, and available sending quota. Higher-impact operations like creating a new account within an agency stay off-limits unless you explicitly add them.
For Agents
Programmatically get receiver count for a client, get active receiver count for a client. Covers 22 operations with bearer authentication.
Use for: I need to receiver count for a client, I want to active receiver count for a client, Search for available mail sending quota, Find all client billing address
Not supported: Does not handle payments, communications, or crm - use for marketing only.
CleverReach email marketing REST API for managing clients, groups, receivers, mailings, blacklists, and forms. The API exposes 22 endpoints secured with bearer authentication.
