Vehicle Databases Python API Docs | dltHub
Build a Vehicle Databases-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.
Last updated:
Vehicle Databases provides a suite of automotive APIs for accessing vehicle specifications, build sheets, and sales history data. The REST API base URL is https://api.vehicledatabases.com and all requests require an authentication key passed in a custom 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 Vehicle Databases data in under 10 minutes.
What data can I load from Vehicle Databases?
Here are some of the endpoints you can load from Vehicle Databases:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| vin_decode | vin-decode/{vin} | GET | data | Basic vehicle specifications by VIN |
| advanced_vin_decode | advanced-vin-decode/v2/{vin} | GET | data | Detailed vehicle specifications by VIN |
| buildsheet | buildsheet/{vin} | GET | data | Detailed vehicle buildsheet (OEM codes) |
| ymmt_specs | ymm-specs/v3/{year}/{make}/{model}/{trim} | GET | data | Vehicle specifications by YMMT |
| vehicle_list | vehicles | GET | Bulk list of vehicles |
How do I authenticate with the Vehicle Databases API?
The API requires an authentication key to be passed in a custom header named 'x-authkey'.
1. Get your credentials
To obtain API credentials, navigate to the provider's website (e.g., vehicledatabases.com or vehdb.com) and sign up for an account. Once registered, log in to your user portal or dashboard. In the dashboard, locate the API section or 'API Tokens' tab, where you can generate, view, and manage your unique API credentials. For some services, your initial key is emailed to you upon registration.
2. Add them to .dlt/secrets.toml
[sources.vehicle_databases_source] api_key = "your_actual_api_key_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 Vehicle Databases 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 vehicle_databases_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline vehicle_databases_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset vehicle_databases_data The duckdb destination used duckdb:/vehicle_databases.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 advanced-vin-decode and search/vehicles from the Vehicle Databases 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 vehicle_databases_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.vehicledatabases.com", "auth": {"type": "api_key", "api_key": api_key, "name": "x-authkey", "location": "header"}, }, "resources": [ {"name": "vin_decode", "endpoint": {"path": "vin-decode/{vin}"}}, {"name": "advanced_vin_decode", "endpoint": {"path": "advanced-vin-decode/v2/{vin}"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="vehicle_databases_pipeline", destination="duckdb", dataset_name="vehicle_databases_data", ) load_info = pipeline.run(vehicle_databases_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("vehicle_databases_pipeline").dataset() sessions_df = data.vin_decode.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM vehicle_databases_data.vin_decode LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("vehicle_databases_pipeline").dataset() data.vin_decode.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 Vehicle Databases 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.
