Load Lever Hiring data to DuckDB

Lever is an applicant tracking and hiring platform that exposes REST APIs for managing job postings, opportunities, requisitions, and related HR data. Everything needed to build a working Lever Hiring → 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 Lever Hiring 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 Lever Hiring 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 Lever Hiring 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.

Lever Hiring API at a glance

These values come from the Lever Hiring API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the Lever Hiring API?

Lever supports two authentication methods: Basic Auth using an API key (where the key is the username and the password is left blank) and OAuth 2.0. For OAuth, requests require an 'Authorization: Bearer <access_token>' header.

1. Get your credentials

1. Sign in to your Lever account as a Super Admin. 2. Navigate to Settings > Integrations and API > API Credentials. 3. Click the Generate New Key button. 4. Provide a name for the integration, configure the necessary read/write permissions under the 'Permissions' heading, and choose whether to allow access to confidential data. 5. Click Generate key to create the credential. 6. Click Copy Key to save the API key securely. Note that you cannot edit a key's permissions once generated; you must delete and recreate it if changes are needed.

2. Add them to .dlt/secrets.toml

Copy
[sources.lever_hiring_source]
api_key = "your_lever_api_key_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 Lever Hiring data can I load into DuckDB?

These are the Lever Hiring endpoints dlt can load into DuckDB:

How do I load only new Lever Hiring records?

Lever Hiring exposes next on opportunities, 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.

Copy
{"name": "opportunities", "endpoint": {
    "path": "opportunities",
    "data_selector": "data",
    "incremental": {"cursor_path": "next", "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 Lever Hiring pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading opportunities and candidates from the Lever Hiring API into DuckDB:

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

@dlt.source
def lever_hiring_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.lever.co/v1",
            "auth": {"type": "http_basic", "username": "REPLACE_ME", "password": api_key},
        },
        "resources": [
            {"name": "opportunities", "endpoint": {"path": "opportunities", "data_selector": "data"}},
            {"name": "requisitions", "endpoint": {"path": "requisitions", "data_selector": "data"}}
        ],
    }
    yield from rest_api_resources(config)


def load_lever_hiring_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="lever_hiring_pipeline",
        destination="duckdb",
        dataset_name="lever_hiring_data",
    )
    load_info = pipeline.run(lever_hiring_source())
    print(load_info)


if __name__ == "__main__":
    load_lever_hiring_to_duckdb()

Run it with python lever_hiring_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 Lever Hiring 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("lever_hiring_pipeline").dataset()
df = data.opportunities.df()
print(df.head())

SQL:

Copy
SELECT * FROM lever_hiring_data.opportunities LIMIT 10;

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

How do I deploy the Lever Hiring 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 Lever Hiring 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 Lever Hiring 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.
