Install Jentic One Beta

Connect the Quaderno API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Quaderno 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%2Fquaderno.io%2Fquaderno" | 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%2Fquaderno.io%2Fquaderno" | 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 API features Management

Automate API features operations by combining multiple Quaderno API endpoints. Agents can update a custom account and then create a custom account in a single workflow.

Call PUT /accounts/{id} to update a custom account, then verify the result

AI Agent Integration via Jentic

AI agents discover and call Quaderno 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 basic, oauth2 tokens manually.

Search Jentic for 'retrieve a custom account', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?

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

Setup

Wiring Quaderno by hand means resolving your account-specific quadernoapp.com host, handling its basic or OAuth2 auth, and shaping each request yourself. Through Jentic you install once, import the Quaderno API from the API Directory, store the credential once, and your agent calls it.

Permission scoping

Quaderno puts the account and address id in the URL path (/accounts/{id}, /addresses/{id}), so a rule can pin your agent to one account or address: it can read and update that record and nothing else. You choose the operations it may call, so ones like creating new accounts are not included unless you add them.

Credential isolation

Your Quaderno 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 'retrieve an account' or 'create a billing address', and Jentic returns the matching Quaderno operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Quaderno API through Jentic.

What authentication does the Quaderno API use?

The Quaderno API uses basic, oauth2 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 retrieve a custom account with the Quaderno API?

Yes. Use the GET /accounts/{id} endpoint. The API returns structured JSON responses that agents can parse and act on directly.

What are the rate limits for the Quaderno 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 retrieve a custom account through Jentic?

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

How many endpoints does the Quaderno API have?

The Quaderno API exposes 89 endpoints covering API features, changelog, registered jurisdictions operations.

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

Yes. Because you run Jentic One yourself, your own rules decide which Quaderno operations and credential the agent may use. Quaderno carries the account and address id in the URL path, such as GET /accounts/{id} and PUT /addresses/{id}, so you can pin the agent to a single account or address and let it read and update only that record. You choose the operations it can call, so write actions like POST /accounts to create a new account stay off unless you explicitly add them.
