For Agents
Programmatically create subscription, list subscriptions. Covers 10 operations.
Use for: I need to subscription, I want to subscriptions, Search for subscription, Find all subscription
Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Piriod 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 | shStep 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 instanceJentic 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.
What an agent can do with Piriod API.
Create subscription
List subscriptions
Get subscription
Update subscription
GET STARTED
Not supported: Does not handle communications, crm, or developer tools — use for payments only.
Piriod API for period/subscription management and billing. The API exposes 10 endpoints.
Cancel subscription
Patterns agents use Piriod API for, with concrete tasks.
★ Payments Operations
Use the Piriod API to perform payments operations programmatically. The API provides 10 endpoints covering core functionality including create subscription, list subscriptions, get subscription.
Call POST /subscriptions to create subscription
Automated Customers Management
Automate customers operations by combining multiple Piriod API endpoints. Agents can list subscriptions and then get subscription in a single workflow.
Call GET /subscriptions to list subscriptions, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Piriod 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 'create subscription', load the operation schema, and execute with Jentic-managed credentials

Three things that make agents converge on Jentic-routed access.
Credential isolation
Piriod API none credentials are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw secrets never enter the agent context.
Intent-based discovery
Agents search by intent (e.g., 'create subscription') and Jentic returns the matching Piriod API operation with its input schema, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct Piriod API integration: 1-3 days for auth handling, response parsing, and error cases. Through Jentic: under 1 hour — search, load schema, execute.
Alternatives and complements available in the Jentic catalogue.

Specific to using Piriod API through Jentic.
What authentication does the Piriod API use?
The Piriod API uses no authentication. Through Jentic, these credentials are stored encrypted in the MAXsystem vault and injected at execution time, so raw secrets never enter the agent context.
Can I create subscription with the Piriod API?
Yes. Use the POST /subscriptions endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Piriod 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 create subscription through Jentic?
Install the Jentic SDK with pip install jentic, authenticate at https://app.jentic.com/sign-up, then search for 'create subscription'. Jentic returns the matching Piriod API operation with its input schema. Load the schema and execute the call — credentials are injected automatically.
How many endpoints does the Piriod API have?
The Piriod API exposes 10 endpoints covering customers, invoices, subscriptions operations.
/customers
Create customer
/customers
List customers
/customers/{id}
Get customer
