Install Jentic One Beta

Connect the Hologram REST API to your agent

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

Capabilities

What an agent can do with Hologram REST API.

Activate cellular SIMs individually or by ICCID range

List devices and retrieve device locations and details

Pause or unpause device or SIM data, individually or in bulk

Change data plans and set overage, SMS, and data-threshold limits

Send SMS and cloud messages to a device

Use Cases

Patterns agents use Hologram REST API for, with concrete tasks.

★ Agent-Managed IoT SIM Fleet

An AI agent operating a fleet of connected devices activates new SIMs, monitors their data usage, and pauses any that exceed a threshold. The Hologram REST API exposes SIM activation, data pause and unpause, and usage-limit operations, so the agent keeps the fleet within budget through Jentic without a developer scripting each call.

Activate a SIM by ICCID and set its data overage limit

Automated Usage Alerts and Response

When a device crosses a usage threshold, an agent needs to see the alert and act. The Hologram REST API lists usage and custom alerts and lets an agent acknowledge them, so a monitoring agent can triage alerts and pause the affected device's data.

List unacknowledged usage alerts and pause data on the devices that triggered them

Device Messaging from an Agent

A remote device needs a command or notification pushed to it. The Hologram REST API sends SMS and cloud messages to a device, so an agent can deliver a message or trigger an action on hardware in the field.

Send a cloud message to a device by its device ID

Key Endpoints

58 endpoints — the hologram rest api manages cellular connectivity for iot fleets, letting you activate sims, list and update devices, and control their data and messaging.

Why Jentic?

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

Setup

Wiring Hologram by hand means base64-encoding your API key for HTTP Basic authentication, sending it on every call, and mapping 58 device, SIM, and alert endpoints yourself. Through Jentic you install once, import the Hologram REST API from the Directory, store your key once, and your agent calls it.

Permission scoping

Devices and SIMs are addressed by ID in the URL path (/api/1/devices/{deviceid}), so a rule can pin your agent to a specific device or link. You choose the operations it may call, so it can pause data or read usage without being able to change plans or add balance.

Credential isolation

Your Hologram API 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 'activate a hologram sim' or 'pause device data', and Jentic returns the matching operation with its input schema so the agent calls the right endpoint.

FAQs

Specific to using Hologram REST API through Jentic.

What authentication does the Hologram REST API use?

The Hologram REST API authenticates with your API key sent over HTTP Basic authentication, per its OpenAPI spec. Through Jentic the key is stored encrypted by your own Jentic One instance and injected when your agent calls the API.

Is there a Hologram API MCP server?

You don't need an MCP server to give your agent the Hologram REST API. Jentic connects it directly from the API Directory: import it, store your API key once, and your agent activates SIMs and manages devices as it needs to. Nothing extra is loaded into the agent's context until a call is made.

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

Yes. You choose which of the 58 operations your agent may call, so you can allow read operations like listing devices and usage while withholding the ones that change plans or add account balance. Every call it makes is logged for review.

Can I pause a device's data through the Hologram REST API?

Yes. The API has an operation to pause or unpause data on a device by its device ID, plus a bulk version, so an agent can stop data on a device that has exceeded its limit.

How do I activate a Hologram SIM through Jentic?

Search Jentic for 'activate a hologram sim', which returns the SIM activation operation with its input schema. Add the Hologram REST API from the Jentic API Directory, store your API key once, and your agent can activate SIMs and manage devices. To run it on your own infrastructure, install Jentic One from its GitHub repo.

For Agents

Manage a Hologram IoT SIM and device fleet: activate SIMs, pause or resume data, change plans, set usage limits, send messages to devices, and read alerts and usage.

Use for: Activate a new SIM by its ICCID, Pause data on a device that is over its limit, Get the current location of a device, Change the data plan for a SIM

Not supported: Does not provision physical hardware or handle payment processing beyond account balance top-ups. Use for managing Hologram SIMs, devices, alerts, and messaging only.

The Hologram REST API manages cellular connectivity for IoT fleets, letting you activate SIMs, list and update devices, and control their data and messaging. It exposes operations to pause or unpause data, change plans, set usage limits and thresholds, retrieve device locations and state history, send SMS and cloud messages to devices, and read alerts, data plans, and usage sessions. Requests authenticate with an API key over HTTP Basic authentication.
