Install Jentic One Beta

Connect the EZ Texting API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the EZ Texting 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://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | 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.

Use Cases

Patterns agents use EZ Texting API for, with concrete tasks.

★ Transactional SMS Sends

Use POST /messages to send transactional SMS notifications such as appointment reminders or order updates from a backend service. Pair with /messages/{id} to fetch the delivery state of any individual message and feed status changes back into the originating system. EZ Texting handles carrier routing and sender IDs while the API surface stays small.

POST /messages with the recipient phone number and reminder copy, then poll GET /messages/{id} to verify the delivery status.

Campaign Audience Management

Build segmented SMS campaigns by maintaining contacts and groups through the /contacts and /groups endpoints. Add subscribers when they opt in, attach them to one or more groups for targeting, and update their attributes when their preferences change. The 17-endpoint surface keeps audience operations explicit and easy to script.

POST /contacts to enrol a new subscriber, then POST /groups/{id} membership to add them to the launch-day campaign group.

Inbound Keyword Autoresponders

Configure inbound SMS keywords through /keywords so that subscribers texting a phrase like JOIN to the short code receive an automated reply and are added to the opt-in list. Keywords drive growth-loop mechanics for SMS marketing programmes and can be combined with group membership for follow-up nurture sends.

POST /keywords with the keyword JOIN and the autoresponder copy, then verify the configuration with GET /keywords/{id}.

MMS with Picture Messaging

Upload an image via /media and reference it from a /messages send to deliver picture messages as part of an MMS campaign. Useful for promotions and event invitations where a visual asset increases engagement, and for transactional sends like badge images or coupon codes that benefit from rich media.

POST /media with the campaign image, then POST /messages referencing the returned media id and the recipient list.

Agent-Driven SMS Workflows via Jentic

An AI agent that manages customer communications can use Jentic to discover and call EZ Texting operations rather than embedding the v2 client. Bearer tokens stay inside your Jentic One instance, so the agent can send transactional SMS, update contacts, and configure keywords without ever holding the raw access token.

Through Jentic, search 'send a transactional SMS', load POST /messages, and execute it with the recipient and message body for the agent's reminder workflow.

Key Endpoints

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your EZ Texting bearer token is stored once, encrypted, by your own Jentic One instance and injected at execution time. The long-lived access token never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'send a transactional SMS' or 'add a contact to a group', and Jentic returns the matching /messages or /contacts operation with its full input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using EZ Texting API through Jentic.

Why is there no official OpenAPI spec for EZ Texting API?

EZ Texting does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call EZ Texting API via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the EZ Texting API use?

The spec declares an HTTP Bearer scheme called bearerAuth. Provision the token from your EZ Texting account and store it in your Jentic One instance so it is supplied as the Authorization header without entering the agent prompt.

Can I send an MMS through the EZ Texting API?

Yes. Upload the image with POST /media, then call POST /messages referencing the returned media id alongside the recipient phone number to deliver a picture-message MMS.

How do I configure a keyword autoresponder?

Call POST /keywords with the inbound keyword and autoresponder copy, then verify with GET /keywords/{id}; subscribers texting that keyword to your assigned number receive the configured reply.

How do I send a transactional SMS through Jentic?

Run pip install jentic, search 'send a transactional SMS', load POST /messages, then execute it with the recipient phone number and message body; Jentic injects the bearer token from the vault.

What are the rate limits for the EZ Texting API?

The spec does not declare explicit rate limits, so respect any 429 responses with backoff and stagger high-volume sends; the EZ Texting account dashboard is the source of truth for the per-tier throughput allowance.

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

Yes. Because Jentic One is self-hosted, you decide which EZ Texting operations your agent can call and which credentials it may use. You can allow only what the workflow needs, such as sending a message with POST /messages or adding a subscriber with POST /contacts, while leaving group and keyword management out unless you choose to include them. The bearer token stays in your own instance and is supplied at execution time, so the agent never holds the raw credential.
