For Agents

Manage subscriptions, customers, products, invoices, components, and payment profiles for usage-based and B2B SaaS billing. Useful for finance ops, billing automation, and revenue management agents.

Install Jentic One Beta

Connect the Chargify API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Chargify 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.

Capabilities

What an agent can do with Chargify API.

Manage the subscription lifecycle through the /subscriptions.json endpoints, including create, update, retrieve, and cancel operations

Maintain customer records with /customers.json (list, create, retrieve, update, delete) and tie them to subscriptions

Define products and product families via /products.json so subscriptions can reference a priced offering

Use Cases

Patterns agents use Chargify API for, with concrete tasks.

★ Usage-Based SaaS Billing

B2B SaaS companies with metered or hybrid pricing use Chargify components to bill on units consumed (API calls, seats, GB processed). The /subscriptions/{subscription_id}/components.json endpoint exposes per-subscription usage and component allocations, letting finance teams report and reconcile usage against the underlying subscription term.

GET /subscriptions/{subscription_id}/components.json for each active subscription and report the current usage totals

Subscription Lifecycle Management

Finance and customer success teams manage subscriptions over their full life: POST /subscriptions.json to start, PUT /subscriptions/{subscription_id}.json to change plan or seat count, DELETE /subscriptions/{subscription_id}.json to cancel. Chargify handles proration and invoicing so the integrator does not have to compute partial-period adjustments manually.

PUT /subscriptions/{subscription_id}.json to change the plan and let Chargify generate the proration invoice

One-Off Charges and Account Adjustments

Sales and support teams add one-off line items — onboarding fees, professional services, overage true-ups — to a subscription via POST /subscriptions/{subscription_id}/charges.json. The charge appears on the subscription's next invoice (or immediately, depending on settings) and is included in revenue reporting alongside recurring components.

POST /subscriptions/{subscription_id}/charges.json with an amount of 250.00 USD for a customer onboarding fee

Payment Profile Hygiene

When a customer rotates cards or asks for their payment data to be removed, finance ops uses /payment_profiles.json to manage stored payment methods. POST creates a new profile, GET inspects the current state, and DELETE /payment_profiles/{payment_profile_id}.json removes the record cleanly so future charges fall back to a different method or fail predictably.

DELETE /payment_profiles/{payment_profile_id}.json when a customer requests their card on file be removed

Agent-Driven Billing via Jentic

An AI agent given an instruction like 'add a $500 services charge to subscription 12345' can resolve the workflow through Jentic. It searches for the one-off charge operation, loads the schema for POST /subscriptions/{subscription_id}/charges.json, and submits the charge — without ever holding the merchant's Chargify credential directly.

Search Jentic for 'add a one-off charge to a subscription' and POST the charge with the agreed amount and description

Why Jentic?

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

Credential isolation

Chargify uses HTTP Basic with the API key as the username. Jentic stores the credential encrypted in the MAXsystem vault, isolating it from the agent context, and injects it only at execution time.

Intent-based discovery

Agents query Jentic with intents like 'create a subscription' or 'add a one-off charge', and Jentic returns the matching Chargify operation with the subscription, customer, and product schema resolved.

Time to first call

Direct Chargify integration: 3-5 days to model subscriptions, customers, components, and payment profiles. Through Jentic: under an hour — search, load, execute against the right resource ID.

FAQs

Specific to using Chargify API through Jentic.

What authentication does the Chargify API use?

Chargify uses HTTP Basic authentication: pass your API key as the username and the literal string 'x' as the password. Through Jentic, the API key is held in the MAXsystem vault and only injected server-side at execution time.

Can I add a one-off charge to an existing subscription with the Chargify API?

Yes. POST /subscriptions/{subscription_id}/charges.json with an amount and memo. Chargify adds the line item to the subscription's next invoice or processes it immediately depending on the merchant's settings.

How do I track metered usage for a subscription?

GET /subscriptions/{subscription_id}/components.json returns the components configured on the subscription with their current usage values. Chargify uses these counts at the next renewal to compute the metered portion of the invoice.

What are the rate limits for the Chargify API?

Chargify does not publish a fixed public rate limit; production limits depend on your plan. Cache /products.json and /customers.json reads where possible and back off on HTTP 429 responses, especially during end-of-billing-period bursts.

How do I create a subscription through Jentic?

Install jentic with pip install jentic, search for 'create a chargify subscription', load the schema for POST /subscriptions.json, and execute with the customer and product IDs. Sign up at https://app.jentic.com/sign-up to get an agent API key.

Does the Chargify API support storing multiple payment methods per customer?

Yes. POST /payment_profiles.json creates a new payment method tied to a customer, GET /payment_profiles/{payment_profile_id}.json inspects an individual record, and DELETE removes one. A customer can hold several stored profiles with one designated as the default for charges.
