Epic Games Unreal Python API Python API Docs | dltHub
Build a Epic Games Unreal Python API-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.
Last updated:
Unreal Engine's Remote Control API is a web server interface that enables external applications to read/write properties and execute functions (including Python logic) within a running Unreal Editor or game instance via HTTP or WebSocket. The REST API base URL is http://127.0.0.1:30010 and All requests require a 'Passphrase' header..
dlt is an open-source Python library that handles authentication, pagination, and schema evolution automatically. dlthub provides AI context files that enable code assistants to generate production-ready pipelines. Install with uv add "dlt[hub]" and start loading Epic Games Unreal Python API data in under 10 minutes.
What data can I load from Epic Games Unreal Python API?
Here are some of the endpoints you can load from Epic Games Unreal Python API:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| remote_info | remote/info | GET | Returns all available HTTP routes in the Remote Control API. | |
| object_call | remote/object/call | PUT | Calls a function exposed by a UObject in the Editor. | |
| object_property | remote/object/property | PUT | Accesses property values exposed by a UObject in the Editor. | |
| object_describe | remote/object/describe | PUT | Retrieves metadata about a UObject in the Editor. | |
| search_assets | remote/search/assets | PUT | Searches for assets in the Content Browser. | |
| remote_batch | remote/batch | PUT | Groups multiple HTTP requests into a single call. |
How do I authenticate with the Epic Games Unreal Python API API?
Authentication is handled by a custom 'Passphrase' HTTP header. The header name is 'Passphrase' and the value is the passphrase configured in the Unreal Engine Remote Control plugin settings.
1. Get your credentials
To obtain credentials for Epic Online Services (EOS) REST APIs, navigate to the Epic Developer Portal (dev.epicgames.com/portal). Log in to your developer account, select your organization, and navigate to the project settings. Within your sandbox environment, you can generate and manage Client Credentials (Client ID and Client Secret) under the Product or Client Policy settings. These credentials are used to authenticate your application with Epic's backend services.
2. Add them to .dlt/secrets.toml
[sources.epic_games_unreal_python_api_source] eos_client_id = "your_client_id_here" eos_client_secret = "your_client_secret_here" eos_product_id = "your_product_id_here" eos_sandbox_id = "your_sandbox_id_here"
dlt reads this automatically at runtime — never hardcode tokens in your pipeline script. For production environments, see setting up credentials with dlt for environment variable and vault-based options.
How do I set up and run the pipeline?
Set up a virtual environment and install dlt:
uv init uv add "dlt[hub]"
1. Install the dlt AI harness:
uv run dlthub ai init --agent <your-agent> # <agent>: claude | cursor | codex
This installs project rules, a secrets management skill, appropriate ignore files, and configures the dlt MCP server for your agent. Learn more →
2. Install the rest-api-pipeline toolkit:
uv run dlthub ai toolkit install rest-api-pipeline
This loads the skills and context about dlt the agent uses to build the pipeline iteratively, efficiently, and safely. The agent uses MCP tools to inspect credentials — it never needs to read your secrets.toml directly. Learn more →
3. Start LLM-assisted coding:
Use /find-source to load data from the Epic Games Unreal Python API API into DuckDB.
The rest-api-pipeline toolkit takes over from here — it reads relevant API documentation, presents you with options for which endpoints to load, and follows a structured workflow to scaffold, debug, and validate the pipeline step by step.
4. Run the pipeline:
uv run python epic_games_unreal_python_api_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline epic_games_unreal_python_api_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset epic_games_unreal_python_api_data The duckdb destination used duckdb:/epic_games_unreal_python_api.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs
Inspect your pipeline and data:
uv run dlthub show
This opens the Pipeline Dashboard where you can verify pipeline state, load metrics, schema (tables, columns, types), and query the loaded data directly.
Python pipeline example
This example loads auth and connect from the Epic Games Unreal Python API API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:
import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def epic_games_unreal_python_api_source(passphrase=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "http://127.0.0.1:30010", "auth": {"type": "bearer", "token": passphrase}, }, "resources": [ {"name": "remote_info", "endpoint": {"path": "remote/info"}}, {"name": "search_assets", "endpoint": {"path": "remote/search/assets"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="epic_games_unreal_python_api_pipeline", destination="duckdb", dataset_name="epic_games_unreal_python_api_data", ) load_info = pipeline.run(epic_games_unreal_python_api_source()) print(load_info)
To add more endpoints, append entries from the resource table to the "resources" list using the same name, path, and data_selector pattern.
How do I query the loaded data?
Once the pipeline runs, dlt creates one table per resource. You can query with Python or SQL.
Python (pandas DataFrame):
import dlt data = dlt.pipeline("epic_games_unreal_python_api_pipeline").dataset() sessions_df = data.remote_info.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM epic_games_unreal_python_api_data.remote_info LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("epic_games_unreal_python_api_pipeline").dataset() data.remote_info.df().head()
See how to explore your data in marimo Notebooks and how to query your data in Python with dataset.
What destinations can I load Epic Games Unreal Python API data to?
dlt supports loading into any of these destinations — only the destination parameter changes:
| Destination | Example value |
|---|---|
| DuckDB (local, default) | "duckdb" |
| PostgreSQL | "postgres" |
| BigQuery | "bigquery" |
| Snowflake | "snowflake" |
| Redshift | "redshift" |
| Databricks | "databricks" |
| Filesystem (S3, GCS, Azure) | "filesystem" |
Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.
