To install the SDK, use pip: 
pip install datalinks
If you want to install the package in an editable development mode:
  1. Clone the repository from your version-control system.
  2. Create a virtual environment with your tool/distro of choice.
  3. Run the following:
pip install -e .

​
Components

​
1. DLConfig

DLConfig reads configurations (e.g., API keys) via environment variables or .env files. This enables dynamic adaptation across deployment environments.

​
2. DataLinksAPI

DataLinksAPI handles interactions with the API. Using it, you can:
  • Ingest data
  • Query or retrieve data with complex parameters
  • Manage namespaces

​
3. Inference Workflow

Use a chain of inference and validation steps defined through classes like ProcessUnstructured, Normalize, and Validate to automate data preparation workflows. 
from datalinks.pipeline import Pipeline, ProcessUnstructured, Normalize, Validate, ValidateModes

# Define an inference pipeline
inference_steps = Pipeline(
   ProcessUnstructured(derive_from="source_field", helper_prompt="This extracts tables."),
   Normalize(target_cols={"email": "email_address"}, mode="all-in-one"),
   Validate(mode=ValidateModes.FIELDS, columns=["email", "phone"]),
)

​
4. Entity Resolution

Supports multiple resolution strategies, configurable via MatchTypeConfig: 
from datalinks.links import MatchTypeConfig, ExactMatch

entity_resolution = MatchTypeConfig(
   # parameters are optional
    exact_match=ExactMatch(minVariation=0.2, minDistinct=0.3)
)

​
5. Loaders

Abstract base loaders (e.g., JSONLoader) allow seamless data ingestion from custom file formats like .json.

​
6. Parametrize LLms

You can choose the model and provider to be used in inference steps (eg.: ProcessUnstructured, Normalize, Validate). 

from datalinks.pipeline import Pipeline, ProcessUnstructured

steps = Pipeline(
        ProcessUnstructured(
            derive_from="text",
            helper_prompt="If you find a numeric field use only the value and omit the rest.",
            model="gpt-4.1-nano-2025-04-14",
            provider="openai"
        )

​
Run Unit Tests

Run tests to verify your implementation: 
tox

​
Using the command-line interface

The SDK also provides a built-in command-line interface (CLI) that can be extended: 
datalinks-client [-h] --verbose <input-folder>
