Load TMDB data to DuckDB
Build a TMDB to DuckDB pipeline with your coding agent. One prompt scaffolds it with the dltHub AI harness, plus the TMDB API base URL, auth, endpoints, and incremental loading.
TMDB is a popular database for movies and TV shows providing a REST API for accessing media metadata and user-related account actions. Everything needed to build a working TMDB → 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 TMDB to DuckDB pipeline
Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.
PromptRunuvx dlthub-init@latestto build a pipeline from TMDB 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 TMDB 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 →
Prefer to write it yourself? Every fact the agent uses is below.
TMDB API at a glance
| Base URL | https://api.themoviedb.org |
| Example endpoint | GET 3/discover/movie |
| Records found at | results |
| Authentication | all requests require an Authorization Bearer token header or an api_key query parameter — sent in the Authorization header, prefixed Bearer |
| Pagination | Page-number |
| Incremental field | page |
| API reference | https://developer.themoviedb.org/docs/authentication-application |
These values come from the TMDB API reference — the authoritative source if anything here looks out of date.
How do I authenticate with the TMDB API?
The primary authentication method is using an 'API Read Access Token' (Bearer token) sent in the 'Authorization' header as 'Bearer <<access_token>>'. Alternatively, some legacy or specific endpoints support authentication via an 'api_key' query parameter.
1. Get your credentials
- Sign in to your TMDB account (or create one) at https://www.themoviedb.org/. 2. Navigate to your Account Settings by clicking your profile icon in the top-right corner and selecting Settings. 3. In the left-hand sidebar of the settings page, click on the API link. 4. If you have not yet created an API key, click on the 'Request an API key' link. 5. Fill out the application form with your project details (a personal portfolio or development URL like localhost works for non-commercial projects). 6. Once approved, your API Key (v3) and API Read Access Token (v4) will be displayed on this same API settings page.
2. Add them to .dlt/secrets.toml
[sources.tmdb_source] access_token = "REPLACE_ME"
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 TMDB data can I load into DuckDB?
These are the TMDB endpoints dlt can load into DuckDB:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| discover_movie | /3/discover/movie | GET | results | Returns a list of movies discovered by criteria. |
| discover_tv | /3/discover/tv | GET | results | Returns a list of TV shows discovered by criteria. |
| movie_top_rated | /3/movie/top_rated | GET | results | Returns the top rated movies. |
| tv_top_rated | /3/tv/top_rated | GET | results | Returns the top rated TV shows. |
| person_popular | /3/person/popular | GET | results | Returns the popular people. |
How do I load only new TMDB records?
TMDB exposes page on 3/discover/movie, so dlt can request only the records that changed since the last run. Set it as the cursor_path and dlt tracks the high-water mark for you between runs.
{"name": "discover_movie", "endpoint": { "path": "3/discover/movie", "data_selector": "results", "incremental": {"cursor_path": "page", "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 TMDB pipeline look like?
A standard dlt REST API pipeline — the same code you would write by hand, loading movie and account from the TMDB API into DuckDB:
import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def tmdb_source(access_token=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.themoviedb.org", "auth": {"type": "bearer", "token": access_token}, }, "resources": [ {"name": "discover_movie", "endpoint": {"path": "3/discover/movie", "data_selector": "results"}}, {"name": "discover_tv", "endpoint": {"path": "3/discover/tv", "data_selector": "results"}} ], } yield from rest_api_resources(config) def load_tmdb_to_duckdb() -> None: pipeline = dlt.pipeline( pipeline_name="tmdb_pipeline", destination="duckdb", dataset_name="tmdb_data", ) load_info = pipeline.run(tmdb_source()) print(load_info) if __name__ == "__main__": load_tmdb_to_duckdb()
Run it with python tmdb_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 TMDB 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):
import dlt data = dlt.pipeline("tmdb_pipeline").dataset() df = data.discover_movie.df() print(df.head())
SQL:
SELECT * FROM tmdb_data.discover_movie LIMIT 10;
See querying your data with dataset and exploring it in marimo notebooks.
How do I deploy the TMDB 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 TMDB 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 TMDB data to?
dlt loads into any of these — only the destination argument changes:
| Destination | Example value |
|---|---|
| PostgreSQL | "postgres" |
| BigQuery | "bigquery" |
| Snowflake | "snowflake" |
| Redshift | "redshift" |
| Databricks | "databricks" |
| Filesystem (S3, GCS, Azure) | "filesystem" |
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.
