Install Jentic One Beta

Connect the Stax API to your agent

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

Automate admin operations by combining multiple Stax API endpoints. Agents can create a merchant and then get all merchants in a single workflow.

Call POST /merchant to create a merchant, then verify the result

AI Agent Integration via Jentic

AI agents discover and call Stax 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 none tokens manually.

Search Jentic for 'enroll a merchant', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?

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

Setup

Wiring the Stax API by hand means learning its request conventions, working through its large merchant and enrollment surface, and threading the merchant id through registration and API-key calls yourself. Through Jentic you install once, import the Stax API from the API Directory, store the credential once, and your agent calls it.

Permission scoping

The Stax API puts the merchant id in the URL path (/merchant/{id}/registration, /merchant/{id}/apikey), so a rule can pin your agent to one merchant: it can read that merchant's registration and nothing else. You choose the operations it may call, so enrollment and API-key creation are not included unless you add them.

Credential isolation

Your Stax 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 'enroll a merchant' or 'read a merchant's registration', and Jentic returns the matching Stax API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Stax API through Jentic.

What authentication does the Stax API use?

The Stax API uses no authentication. 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 enroll a merchant with the Stax API?

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

What are the rate limits for the Stax 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 enroll a merchant through Jentic?

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

How many endpoints does the Stax API have?

The Stax API exposes 122 endpoints covering admin, charge, credit operations.

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

Yes. Because you run Jentic One yourself, self-hosted, your own rules decide which Stax API operations and credentials the agent may use. The Stax API carries the merchant id in the URL path, as in /merchant/{id}/registration and /merchant/{id}/apikey, so you can pin the agent to a single merchant and let it read only that merchant's registration. You choose the operations it may call, so merchant enrollment via POST /admin/enroll and API-key creation stay out of reach unless you explicitly grant them.
