People Data Labs Python API Docs | dltHub

Build a People Data Labs-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.

Last updated:

People Data Labs provides APIs for enriching, searching, and identifying person and company profiles. The REST API base URL is https://api.peopledatalabs.com/v5 and Requests require an API key passed via the X-Api-Key header or api_key query parameter..

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 People Data Labs data in under 10 minutes.


What data can I load from People Data Labs?

Here are some of the endpoints you can load from People Data Labs:

ResourceEndpointMethodData selectorDescription
person_search/v5/person/searchPOSTdataSearch for person profiles using queries
company_search/v5/company/searchPOSTdataSearch for company profiles using queries
person_enrichment/v5/person/enrichmentGETEnrich a person profile
company_enrichment/v5/company/enrichmentGETEnrich a company profile
person_changelog/v5/person/changelogGETupdatedQuery the changelog of person records

How do I authenticate with the People Data Labs API?

Authentication is performed by including your API key either as a query parameter named 'api_key' or in the request header using the key 'X-Api-Key'.

1. Get your credentials

To obtain your People Data Labs API credentials: 1. Navigate to the People Data Labs Dashboard (https://dashboard.peopledatalabs.com). 2. If you do not have an account, sign up at https://www.peopledatalabs.com/signup. 3. Log in to your account. 4. Once on the Home page or in the navigation menu, locate the 'API Keys' section. 5. Copy your 'Active Key' or generate a new one if necessary. Note that this is a secret key and should be kept secure.

2. Add them to .dlt/secrets.toml

[sources.people_data_labs_source] api_key = "your_pdl_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 People Data Labs 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 people_data_labs_pipeline.py

If everything is configured correctly, you'll see output like this:

Pipeline people_data_labs_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset people_data_labs_data The duckdb destination used duckdb:/people_data_labs.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 person/enrich and person/search from the People Data Labs 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 people_data_labs_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.peopledatalabs.com/v5", "auth": {"type": "api_key", "api_key": api_key, "name": "X-Api-Key", "location": "header"}, }, "resources": [ {"name": "person_search", "endpoint": {"path": "v5/person/search", "data_selector": "data"}}, {"name": "person_changelog", "endpoint": {"path": "v5/person/changelog", "data_selector": "updated"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="people_data_labs_pipeline", destination="duckdb", dataset_name="people_data_labs_data", ) load_info = pipeline.run(people_data_labs_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("people_data_labs_pipeline").dataset() sessions_df = data.person_search.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM people_data_labs_data.person_search LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("people_data_labs_pipeline").dataset() data.person_search.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 People Data Labs data to?

dlt supports loading into any of these destinations — only the destination parameter changes:

DestinationExample 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.
