Install Jentic One Beta
Connect the Riot Games API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Riot Games 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%2Friotgames.com%2Friotgames" | 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%2Friotgames.com%2Friotgames" | 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 Riot Games API.
Get account by PUUID
Manage social media data programmatically
Integrate Riot Games API into automated workflows
Query and filter Riot Games API records by parameters
Monitor Riot Games API operational status and events
Use Cases
Patterns agents use Riot Games API for, with concrete tasks.
★ Social Media Operations
Use the Riot Games API to perform social media operations programmatically. The API provides 24 endpoints covering core functionality including get account by puuid, get account by riot id, get current account.
Call GET /riot/account/v1/accounts/by-puuid/{puuid} to get account by puuid
Automated Account Management
Automate account operations by combining multiple Riot Games API endpoints. Agents can get account by riot id and then get current account in a single workflow.
Call GET /riot/account/v1/accounts/by-riot-id/{gameName}/{tagLine} to get account by riot id, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Riot Games 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, oauth2 tokens manually.
Search Jentic for 'get account by puuid', 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 Riot Games API by hand means passing your key in the X-Riot-Token header, optionally running the Riot Sign On OAuth flow for user endpoints, and routing every call to the correct regional host such as americas or europe. Through Jentic you install once, import the Riot Games API from the API Directory, store the credentials once, and your agent calls it.
Permission scoping
Riot Games puts the identifier in the URL path (/riot/account/v1/accounts/by-puuid/{puuid}, /lol/summoner/v4/summoners/{encryptedSummonerId}), so a rule can pin your agent to one account or summoner and its lookups. You choose the operations it may call, and since these are read-only account and mastery reads the agent has no write path unless you add one.
Credential isolation
Your Riot Games API key and OAuth credentials are stored once, encrypted, by your own Jentic One instance and injected at execution time. They never enter the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'get an account by riot id' or 'look up champion mastery', and Jentic returns the matching Riot Games API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Riot Games API through Jentic.
What authentication does the Riot Games API use?
The Riot Games API uses apiKey, 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 get account by puuid with the Riot Games API?
Yes. Use the GET /riot/account/v1/accounts/by-puuid/{puuid} endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Riot Games 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 account by puuid through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'get account by puuid'. Jentic returns the matching Riot Games API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Riot Games API have?
The Riot Games API exposes 24 endpoints covering account, summoner, champion mastery operations.
Can I limit what my agent is allowed to do with the Riot Games API?
Yes. Because you self-host Jentic One, your own rules decide which Riot Games API operations and credentials the agent may use. Since the identifier sits in the URL path (for example /riot/account/v1/accounts/by-puuid/{puuid} and /lol/summoner/v4/summoners/{encryptedSummonerId}), you can pin the agent to one account or summoner and its lookups, and pick exactly which operations it may call. These are read-only account, summoner, and champion-mastery reads, so the agent has no write path unless you grant one.
