Install Jentic One Beta
Connect the 511 SF Bay Transit API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the 511 SF Bay Transit 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 | sh2
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 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.

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Your 511 SF Bay Transit API key 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 'list GTFS transit operators' or 'get real-time vehicle positions', and Jentic returns the matching 511 SF Bay Transit API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.
