For Agents

Create products, manage subscription billing, process transactions, and handle adjustments with Paddle as merchant of record. Paddle handles sales tax, VAT, and compliance automatically.

Install Jentic One Beta

Connect the Paddle API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Paddle 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 Paddle API for, with concrete tasks.

★ AI Agent Billing Automation

AI agents manage Paddle billing through Jentic without storing API tokens directly. An agent searches for 'create a Paddle subscription' via Jentic, receives the operation schema with required customer and price fields, and executes the call with credential isolation. Transaction monitoring, invoice retrieval, and refund processing follow the same intent-based pattern, all while Paddle handles tax compliance.

Search Jentic for 'create a Paddle subscription', load the schema, create a subscription for a customer on a monthly price, then verify the subscription status is active

SaaS Product Billing with Tax Compliance

Sell software subscriptions globally with Paddle acting as merchant of record, meaning Paddle collects payment from customers, calculates and remits sales tax and VAT in 200+ countries, and pays the net revenue to your bank account. You define products and prices, Paddle handles checkout, invoicing, and tax obligations. This eliminates the need for tax registration in multiple jurisdictions.

Create a product, add a monthly price of $29 USD, create a customer, then retrieve a subscription to confirm tax was calculated and the total includes VAT

Transaction and Refund Management

Track payment transactions from initiation through completion with full details on payment method, tax breakdown, and settlement status. Issue refunds and credits via the adjustments endpoint, specifying the original transaction ID, refund amount, and reason. Paddle handles the refund processing and adjusts the payout to your account accordingly.

Retrieve a completed transaction by ID, create an adjustment of type refund for the full amount with reason 'customer_request', then verify the adjustment status

Subscription Lifecycle and Upgrades

Manage subscription state transitions including upgrades, downgrades, pauses, and cancellations with automatic proration. When a customer changes plans mid-cycle, Paddle calculates the credit for unused time and charges the difference immediately or applies it to the next invoice. Cancellations can be immediate or scheduled for the end of the current billing period.

Update a subscription to a higher-tier price, verify the proration credit was applied, then cancel the subscription effective at period end using POST /subscriptions/{id}/cancel

Why Jentic?

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

Credential isolation

Paddle Bearer API keys are stored encrypted in the Jentic MAXsystem vault. Agents receive scoped access tokens — the raw API key never enters the agent's context window or logs.

Intent-based discovery

Agents search by intent (e.g., 'create a subscription' or 'issue a refund') and Jentic returns the matching Paddle operation with its full request schema, so the agent constructs the correct payload without browsing Paddle documentation.

Time to first call

Direct Paddle integration: 2-4 days for auth, product/price setup, subscription flow, and webhook configuration. Through Jentic: under 1 hour — search, load schema, execute with credential isolation.

FAQs

Specific to using Paddle API through Jentic.

Why is there no official OpenAPI spec for Paddle API?

Paddle does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Paddle API via structured tooling. It is validated against the live API and kept up to date. Sign up at https://app.jentic.com/sign-up to get started.

What authentication does the Paddle API use?

The Paddle API uses Bearer token authentication. Pass your API key in the Authorization header as 'Bearer {api_key}'. Keys are generated in the Paddle dashboard under Developer Tools > Authentication. Through Jentic, your Paddle API key is stored encrypted in the MAXsystem vault — agents receive scoped access without seeing the raw token.

How does Paddle handle sales tax and VAT?

As merchant of record, Paddle automatically calculates sales tax and VAT for 200+ countries based on the customer's location and your product's tax category. The tax amount is included in transaction totals and Paddle remits directly to tax authorities. You receive net revenue after tax. Transaction details via GET /transactions/{transaction_id} show the full tax breakdown.

What are the rate limits for the Paddle API?

Paddle applies rate limits of 100 requests per minute for write operations (POST, PUT, PATCH, DELETE) and 200 requests per minute for read operations (GET). If exceeded, the API returns HTTP 429 with a Retry-After header. Higher limits are available on enterprise plans.

How do I create a subscription through the Paddle API via Jentic?

Search Jentic for 'create a Paddle subscription' to find the subscription creation flow. You need a customer ID and price ID (create these first via POST /customers and POST /prices). The subscription links the customer to a recurring price with automatic billing. Jentic loads the full schema so your agent knows which fields are required. Sign up at https://app.jentic.com/sign-up to get started.

Can I issue refunds through the Paddle API?

Yes. Create an adjustment via POST /adjustments with action 'refund', the original transaction_id, and the items to refund. You can refund full or partial amounts. Paddle processes the refund to the customer's original payment method and deducts the amount from your next payout. The adjustment response includes the refund status and breakdown.

Does the Paddle API support multiple currencies?

Yes. Prices can be configured in multiple currencies (USD, EUR, GBP, and 20+ others). Each price object specifies the currency and amount. When a customer subscribes, the transaction is processed in the price's currency. Paddle handles currency conversion for payouts to your bank account if your payout currency differs.
