Programmatically execute graphql query. Covers 1 operations with bearer authentication.
Use for: I need to execute graphql query, I want to integrate Railway API into my workflow, Search for available Railway API operations, Get the API schema for Railway API
Not supported: Does not handle payments, communications, or crm - use for cloud infrastructure only.
Railway cloud hosting GraphQL API. The API exposes 1 endpoints secured with bearer authentication.
Install Jentic One Beta
Connect the Railway API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Railway 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%2Frailway.app%2Frailway" | 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%2Frailway.app%2Frailway" | 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 Railway API.
Execute GraphQL query
Access Railway API cloud infrastructure resources via REST API
Query Railway API endpoints with structured JSON responses
Authenticate requests with bearer credentials managed by Jentic
Access Railway API resources programmatically via REST
Use Cases
Patterns agents use Railway API for, with concrete tasks.
★ Cloud Infrastructure Operations
Use the Railway API to perform cloud infrastructure operations programmatically. The API provides 1 endpoints covering core functionality including execute graphql query.
Call POST /graphql/v2 to execute graphql query
Data Retrieval and Monitoring
Query Railway API endpoints to retrieve structured data for monitoring, reporting, or downstream processing. The API returns JSON responses that agents can parse directly, enabling automated data collection workflows.
Query the Railway API API to retrieve current data and verify the response structure
AI Agent Integration via Jentic
AI agents discover and call Railway 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 bearer tokens manually.
Search Jentic for 'execute graphql query', load the operation schema, and execute with Jentic-managed credentials

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Railway API by hand means learning its bearer auth and building your own client around a single GraphQL endpoint where every action is a query or mutation you have to compose. Through Jentic you install once, import the Railway API from the API Directory, store the bearer token once, and your agent calls it.
Permission scoping
Railway exposes one GraphQL endpoint (POST /graphql/v2), so scoping is operations-only: you limit the agent to the operations it needs, such as querying project and service state, rather than pinning it to a single resource in the URL. You choose which GraphQL operations it may run, so mutations you do not want are not included unless you add them.
Credential isolation
Your Railway bearer token 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 Railway projects' or 'trigger a deployment', and Jentic returns the matching Railway operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Railway API through Jentic.
What authentication does the Railway API use?
The Railway API uses a Bearer token in the Authorization 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 execute graphql query with the Railway API?
Yes. Use the POST /graphql/v2 endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Railway 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 execute graphql query through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'execute graphql query'. Jentic returns the matching Railway API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Railway API have?
The Railway API exposes 1 endpoints covering graphql operations.
Can I limit what my agent is allowed to do with the Railway API?
Yes. Because you run Jentic One yourself, your own rules decide which Railway operations and credentials the agent can use. The Railway API is a single GraphQL endpoint (POST /graphql/v2), so scoping is operations-only: you choose which GraphQL operations the agent may run, such as read-only queries of project and service state, and you leave out any mutations you do not want it to call. Your bearer token stays stored encrypted in your instance and is injected only for the operations you have allowed.
