For Agents
Programmatically get transit routes which are near a location, get transit stops which are near a location. Covers 16 operations with apiKey authentication.
Use for: I need to transit routes which are near a location, I want to transit stops which are near a location, Search for upcoming departures for all routes serving a stop, Find all plan a trip from origin to destination (otp)
Not supported: Does not handle payments, communications, or crm - use for maps and geolocation only.
API provided by data from transit.app. The API exposes 16 endpoints secured with apiKey authentication.
Install Jentic One Beta
Connect the Transit API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Ftransitapp.com%2Ftransitapp" | sh2
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%2Ftransitapp.com%2Ftransitapp" | 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.
Capabilities
What an agent can do with Transit API.
Get transit routes which are near a location
Plan a trip from origin to destination (OTP)
Estimate a trip plan duration (Preview)
Query and filter Transit API records by parameters
Monitor Transit API operational status and events
Use Cases
Patterns agents use Transit API for, with concrete tasks.
★ Maps and Geolocation Operations
Use the Transit API to perform maps geolocation operations programmatically. The API provides 16 endpoints covering core functionality including get transit routes which are near a location, get transit stops which are near a location, get upcoming departures for all routes serving a stop.
Call GET /public/nearby_routes to get transit routes which are near a location
Automated Public transport Management
Automate public transport operations by combining multiple Transit API endpoints. Agents can get transit stops which are near a location and then get upcoming departures for all routes serving a stop in a single workflow.
Call GET /public/nearby_stops to get transit stops which are near a location, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Transit 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 apiKey tokens manually.
Search Jentic for 'get transit routes which are near a location', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Transit API by hand means setting up its apiKey header auth against external.transitapp.com and handling error responses yourself. Through Jentic you install once, import the Transit API from the API Directory, store the API key once, and your agent calls it.
Permission scoping
The Transit API is read-only, with locations passed as query parameters rather than owned resource ids in the URL path, so scope the agent to the operations it needs, such as nearby routes, nearby stops, or stop departures, and leave out anything the workflow does not require. Every operation you allow is one you have chosen.
Credential isolation
Your 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 'get transit routes near a location' or 'get upcoming stop departures', and Jentic returns the matching Transit API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Transit API through Jentic.
What authentication does the Transit API use?
The Transit API uses an API key passed in the `apiKey` header. 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 get transit routes which are near a location with the Transit API?
Yes. Use the GET /public/nearby_routes endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Transit 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 get transit routes which are near a location through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'get transit routes which are near a location'. Jentic returns the matching Transit API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Transit API have?
The Transit API exposes 16 endpoints covering public transport, shared mobility operations.
Can I limit what my agent is allowed to do with the Transit API?
Yes. Because Jentic One is self-hosted, you decide which Transit API operations your agent may call, so you can allow just the ones a workflow needs, such as GET /public/nearby_routes, GET /public/nearby_stops, or GET /public/stop_departures, and leave out trip planning or placemark lookups. The Transit API is read-only and takes locations as query parameters, so an allowed agent can fetch nearby routes and departures but cannot create or change anything. Your API key is held encrypted by your own instance and injected at call time, so the agent only ever exercises the operations you have permitted.
