Install Jentic One Beta

Connect the Cuponerapp API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Cuponerapp 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%2Fcuponerapp.com%2Fcuponerapp" | 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%2Fcuponerapp.com%2Fcuponerapp" | 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.

Coupon Validation and Redemption

Before honouring a discount, a workflow needs to know a coupon is valid and then mark it used. The Cuponerapp API returns a coupon's details for validation and redeems it by ID, so an agent can check a code, apply it to a price, and redeem it once the purchase completes.

Fetch a coupon's details to confirm it is valid, then redeem it by ID after the order is paid

Subscription Status Checks

Features that depend on an active subscription need a quick way to confirm it. The Cuponerapp API reports a user's subscription status, letting an agent gate premium actions or prompt a user to renew before continuing.

Read a user's subscription status and only continue with a premium action if the subscription is active

Key Endpoints

Why Jentic?

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

Setup

Wiring Cuponerapp by hand means obtaining and refreshing a JWT bearer token and sequencing the checkout, payment, and coupon calls yourself. Through Jentic you install once, import Cuponerapp from the API Directory, store the token once, and your agent calls the operations directly.

Permission scoping

You choose which of the five operations your agent may call, and the coupon redemption operation addresses a coupon by ID in the URL path, so a rule can bound it to specific coupons. You might allow checkout pricing and coupon lookup while blocking payment processing.

Credential isolation

Your Cuponerapp bearer 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 'redeem a coupon for a user', and Jentic returns the matching Cuponerapp operation with its input schema so the agent calls it with the right coupon ID.

FAQs

Specific to using Cuponerapp API through Jentic.

What authentication does the Cuponerapp API use?

The Cuponerapp API authenticates every request with a bearer token in JWT format, sent in the Authorization header per its OpenAPI spec. Through Jentic the token is stored once by your own self-hosted instance and injected when the agent calls, so it never appears in the agent's prompt or logs.

Is there a Cuponerapp MCP server?

You don't need an MCP server to give your agent the Cuponerapp API. Jentic connects it directly from the API Directory: import it, store your bearer token once, and your agent calls the checkout, payment, and coupon operations. Operations are discovered on demand, so nothing extra loads into the agent's context.

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

Yes. You choose which of the five operations the agent may call, and the coupon redemption operation addresses a coupon by its ID in the URL path, so a rule can bound it to specific coupons. You might allow price calculation and coupon lookup while blocking payment processing, with every call logged.

Can the Cuponerapp API process a payment and apply a coupon in the same flow?

Yes. The checkout price operation returns the total with any coupon discount applied, the payment operation processes the charge, and the redemption operation marks the coupon used, so an agent can run price, pay, and redeem as one sequence.

What are the rate limits for the Cuponerapp API?

The OpenAPI spec does not specify rate limits. Check the Cuponerapp documentation at https://cuponerapp.com for current limits before running high-volume checkout or redemption jobs.

How do I redeem a coupon through Jentic?

Search Jentic by intent, for example 'redeem a coupon for a user', and Jentic returns the redemption operation with its input schema. Your agent supplies the coupon ID and reads back the result. To run it on your own infrastructure, install Jentic One from its GitHub repo.
