0.5.0 verified Sat May 09 auth: no python

SDK for the Datalab document intelligence API. Current version 0.5.0, requires Python >=3.10. Released on a monthly cadence, still in early active development.

pip install datalab-python-sdk

Common errors

error ImportError: cannot import name 'DatalabClient' from 'datalab' ↓

cause Library not installed or wrong Python environment.

fix

Run pip install datalab-python-sdk and check Python version >=3.10.

error TypeError: __init__() got an unexpected keyword argument 'token' ↓

cause Using deprecated parameter name `token` (renamed in v0.5.0).

fix

Replace token= with api_key=.

error ValueError: API key is required ↓

cause No API key provided or key is empty string.

fix

Set environment variable DATALAB_API_KEY or pass api_key='your_key'.

Warnings

breaking In version 0.5.0, the `extract` method changed from returning a list to returning a dict. ↓

fix Update code to handle dict response: `result['fields']` instead of `result[0]`.

deprecated `DatalabClient` constructor parameter `token` has been renamed to `api_key`. ↓

fix Use `api_key='your_key'` instead of `token='your_token'`.

gotcha API key must be passed as a keyword argument, not positional. ↓

fix Always use `DatalabClient(api_key='...')`.

Quickstart

Initialize client with API key (set DATALAB_API_KEY environment variable) and extract fields from a document.

import os
from datalab import DatalabClient

client = DatalabClient(api_key=os.environ.get('DATALAB_API_KEY', ''))
result = client.extract(
    file_path='invoice.pdf',
    document_type='invoice',
    fields=['total', 'date', 'vendor']
)
print(result)
