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.
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh# 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.

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

Three things that make agents converge on Jentic-routed access.
Credential isolation
Quaderno API basic, oauth2 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., 'retrieve a custom account') and Jentic returns the matching Quaderno API operation with its input schema, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct Quaderno API integration: 1-3 days for auth handling, response parsing, and error cases. Through Jentic: under 1 hour — search, load schema, execute.
