Load World Creator data to DuckDB

World Creator is a terrain and landscape generator that provides a REST API for accessing data and integration with other tools. Everything needed to build a working World Creator → DuckDB pipeline is on this page: the API's base URL, authentication, endpoints, pagination and incremental field — plus a prompt that hands the whole job to your coding agent.

Build your World Creator to DuckDB pipeline

Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.

PromptCopy prompt
Run uvx dlthub-init@latest to build a pipeline from World Creator to DuckDB and run it on dltHub

That scaffolds a dltHub workspace and installs the dltHub AI harness — the project rules, the secrets-management skill, and the dlt MCP server your agent needs to work safely. From there it reads the World Creator API, proposes the endpoints to load, then writes, runs and validates the pipeline while you review rather than type. Credentials are inspected through MCP tools, so your agent never reads secrets.toml itself. How the LLM-native workflow works →

World Creator API at a glance

These values come from the World Creator API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the World Creator API?

Authentication uses a bearer token provided in the Authorization header.

1. Get your credentials

World Creator does not currently expose a direct, public-facing REST API for customer data management that utilizes standard API key authentication. The dltHub integration for World Creator typically leverages specific documentation-based endpoints or structured data exports designed for programmatic access via HTTP GET requests, rather than a traditional API key-based system. For standard World Creator software usage, you must use your email and a seat-specific password (generated via the Customer Portal) to activate the application; these credentials should not be confused with API authentication tokens. If you are developing a data pipeline using dlt, configure your credentials by defining an environment variable or a entry in your secrets.toml file as instructed by your data integration platform's specific loader module.

2. Add them to .dlt/secrets.toml

Copy
[sources.world_creator_source]
access_token = "your_access_token_here"

dlt reads this file automatically at runtime. With the harness, the setup-secrets skill prompts you for the values and never handles the raw credential in chat. For production, see setting up credentials with dlt.

What World Creator data can I load into DuckDB?

These are the World Creator endpoints dlt can load into DuckDB:

---

How do I load only new World Creator records?

The World Creator API reference does not document a timestamp or sequence field for these endpoints, so there is nothing to advertise here as verified. Pick a field from the endpoints table above that increases with every write, then set it as the cursor_path.

Copy
{"name": "terrain_shape_layers", "endpoint": {
    "path": "reference/terrain/shape-layers",
    # Replace with a field that increases on every write.
    "incremental": {"cursor_path": "REPLACE_ME", "initial_value": "2024-01-01T00:00:00Z"},
}}

On the first run dlt loads everything from initial_value; on every run after that it requests only what changed and appends with write_disposition="merge" if you set a primary key. See incremental loading.

What does the generated World Creator pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading reference/terrain/shape-layers and reference/terrain/shape-layers/path from the World Creator API into DuckDB:

Copy
import dlt
from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources

@dlt.source
def world_creator_source(access_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://docs.world-creator.com/",
            "auth": {"type": "bearer", "token": access_token},
        },
        "resources": [
            {"name": "terrain_shape_layers", "endpoint": {"path": "reference/terrain/shape-layers"}},
            {"name": "scene", "endpoint": {"path": "reference/scene"}}
        ],
    }
    yield from rest_api_resources(config)


def load_world_creator_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="world_creator_pipeline",
        destination="duckdb",
        dataset_name="world_creator_data",
    )
    load_info = pipeline.run(world_creator_source())
    print(load_info)


if __name__ == "__main__":
    load_world_creator_to_duckdb()

Run it with python world_creator_pipeline.py. The agent iterates on this until it loads cleanly — you review and approve, rather than write it from scratch.

How do I query World Creator data in DuckDB?

dlt creates one table per resource. Query the loaded data with Python or SQL — or ask your agent to, through the MCP server's execute_sql_query tool.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("world_creator_pipeline").dataset()
df = data.terrain_shape_layers.df()
print(df.head())

SQL:

Copy
SELECT * FROM world_creator_data.terrain_shape_layers LIMIT 10;

See querying your data with dataset and exploring it in marimo notebooks.

How do I deploy the World Creator to DuckDB pipeline in production?

The pipeline runs locally, which is ideal for prototyping and one-off analysis. When you need it on a schedule, monitored on every load, and shared with your team, deploy the same dlt code on the dltHub platform — no infrastructure to maintain. The prompt above already ends with "run it on dltHub", so your agent can take it there directly.

• Deploy & schedule — run the pipeline as a managed job with automatic retries.
• Monitor — observable job queues, alerting, and load metrics for every run.
• Transform — promote raw World Creator loads into governed, documented models.
• Visualize & share — explore data in notebooks and publish live dashboards instead of static screenshots.

What other destinations can I load World Creator data to?

dlt loads into any of these — only the destination argument changes:

Set dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. On the dltHub platform the same pipeline runs against a managed Iceberg lakehouse. See the full destinations list.
