Install Jentic One Beta

Connect the SendZen API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the SendZen 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%2Fsendzen.io%2Fsendzen" | sh

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%2Fsendzen.io%2Fsendzen" | sh
jentic register       # connects your agent to your Jentic One instance

Jentic 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.

Data Retrieval and Monitoring

Query SendZen API resources on a schedule to track changes, generate alerts, or feed downstream dashboards. Agents poll relevant endpoints, compare against previous state, and trigger actions when thresholds are crossed.

Poll the primary SendZen API endpoint, compare response to last known state, and alert if changed

AI Agent Integration via Jentic

AI agents discover and call SendZen 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 'send a message', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring SendZen by hand means obtaining a bearer token and attaching it to every message request yourself. Through Jentic you install once, import SendZen from the API Directory, store the token once, and your agent calls it.

Permission scoping

SendZen sends the message target in the request body, not the URL path, so limit the agent to the operations it needs, such as sending a message. You choose the operations it may call, so it holds only that capability unless you add more.

Credential isolation

Your SendZen 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 'send a message', and Jentic returns the matching SendZen operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using SendZen API through Jentic.

What authentication does the SendZen API use?

The SendZen 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 send a message with the SendZen API?

Yes. Use the POST /v1/messages endpoint. The API returns structured JSON responses that agents can parse and act on directly.

What are the rate limits for the SendZen 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 send a message through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'send a message'. Jentic returns the matching SendZen API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

How many endpoints does the SendZen API have?

The SendZen API exposes 1 endpoints covering messages operations.

Can I limit what my agent is allowed to do with the SendZen API?

Yes. Jentic One is self-hosted by you, so your own rules decide which SendZen operations and credentials the agent may use. Since the SendZen API exposes only the send-a-message operation (POST /v1/messages) and carries the message target in the request body rather than the URL path, you scope the agent to just that operation, and it holds only that capability unless you grant more. Your bearer token is stored once by your own Jentic One instance and injected at execution time, so the agent can send messages without ever seeing the raw secret.
