Load Deltek ComputerEase data to DuckDB

Deltek ComputerEase REST Service is a collection of HTTP endpoints that allows custom applications to integrate and interact with Deltek ComputerEase application data. Everything needed to build a working Deltek ComputerEase → 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 Deltek ComputerEase 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 Deltek ComputerEase 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 Deltek ComputerEase 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.

Deltek ComputerEase API at a glance

These values come from the Deltek ComputerEase API reference — the authoritative source if anything here looks out of date.

How do I authenticate with the Deltek ComputerEase API?

Requests require an 'Authorization' header containing the API Key. The API Key is a JWT that remains valid for 24 hours, after which it must be rotated using a Refresh Token.

1. Get your credentials

1. Contact your ComputerEase administrator to request API access. 2. The administrator navigates to Configure > API in the ComputerEase application. 3. The administrator creates an API user, providing a Name, Email, and assigning the necessary API Data Access Management groups. 4. An invitation email is sent to the specified email address. 5. Open the email and click the confirmation link. 6. Upon verification, the screen will display your API Key and Refresh Token. Copy and store these credentials immediately, as they are only shown one time.

2. Add them to .dlt/secrets.toml

Copy
[sources.deltek_computerease_source]
api_key = "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 Deltek ComputerEase data can I load into DuckDB?

These are the Deltek ComputerEase endpoints dlt can load into DuckDB:

How do I load only new Deltek ComputerEase records?

Deltek ComputerEase exposes cursor on catalog/jobs, 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": "jobs", "endpoint": {
    "path": "catalog/jobs",
    "incremental": {"cursor_path": "cursor", "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 Deltek ComputerEase pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading Rotate Application Key and Get Data (Note: endpoints are documented under the ComputerEase REST Service collection) from the Deltek ComputerEase API into DuckDB:

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

@dlt.source
def deltek_computerease_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.computerease.com/v1",
            "auth": {"type": "bearer", "token": api_key},
        },
        "resources": [
            {"name": "jobs", "endpoint": {"path": "catalog/jobs"}},
            {"name": "employees", "endpoint": {"path": "catalog/employees"}}
        ],
    }
    yield from rest_api_resources(config)


def load_deltek_computerease_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="deltek_computerease_pipeline",
        destination="duckdb",
        dataset_name="deltek_computerease_data",
    )
    load_info = pipeline.run(deltek_computerease_source())
    print(load_info)


if __name__ == "__main__":
    load_deltek_computerease_to_duckdb()

Run it with python deltek_computerease_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 Deltek ComputerEase 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("deltek_computerease_pipeline").dataset()
df = data.jobs.df()
print(df.head())

SQL:

Copy
SELECT * FROM deltek_computerease_data.jobs LIMIT 10;

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

How do I deploy the Deltek ComputerEase 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 Deltek ComputerEase 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 Deltek ComputerEase 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.
