Install Jentic One Beta

Connect the Sendon API to your agent

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

Automated SMS Management

Automate sms operations by combining multiple Sendon API endpoints. Agents can list message groups and then get message details in a single workflow.

Call GET /msg/groups to list message groups, then verify the result

AI Agent Integration via Jentic

AI agents discover and call Sendon 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 basic tokens manually.

Search Jentic for 'send text message', load the operation schema, and execute with Jentic-managed credentials

Key Endpoints

18 endpoints — sendon sdk api for sending sms, kakao alimtalk, rcs messages, and managing messaging channels and templates.

Why Jentic?

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

Setup

Wiring the Sendon API by hand means setting up its HTTP basic auth against sdk.sendon.io and handling status codes yourself. Through Jentic you install once, import the Sendon API from the API Directory, store the credential once, and your agent calls it.

Permission scoping

The Sendon API puts the message group id in the URL path (/msg/group/{id}/send and /msg/group/{id}/cancel), so a rule can pin your agent to one message group. You choose the operations it may call, so ones like cancelling a group send are not included unless you add them.

Credential isolation

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

FAQs

Specific to using Sendon API through Jentic.

What authentication does the Sendon API use?

The Sendon API uses HTTP Basic authentication with username and password. 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 text message with the Sendon API?

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

What are the rate limits for the Sendon 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 text message through Jentic?

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

How many endpoints does the Sendon API have?

The Sendon API exposes 18 endpoints covering sms, alimtalk, brand message operations.

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

Yes. Because you run Jentic One yourself, your own rules decide which Sendon operations the agent may call and which stored credential it uses, so you can allow sending a text message with POST /msg/send while leaving out actions like cancelling a group send. Since the Sendon API carries the message group id in the URL path for /msg/group/{id}/send and /msg/group/{id}/cancel, a rule can pin the agent to a single message group. Operations you do not explicitly grant stay off limits.
