Authentication

In order to access the private data of DACE, an authentication system has been implemented. This one works very simply, it just requires three things detailed in the following subsections:

• A DACE account

• An API key

• A local .dacerc file

[user]
key = apiKey:<xxx-xxx-xxx>

[user]
key = apiKey:12345678-1234-5678-1234-567812345678

printf '[user]\nkey = apiKey:%s\n' "your-api-key-here" > ~/.dacerc

Quickstart

# Import the ready-to-use exoplanet instance
from dace_query.exoplanet import Exoplanet

# Retrieve data from the exoplanet database
result: dict = Exoplanet.query_database(limit=10, output_format='dict')

# Get the planet names
planet_names: list = result.get('obj_id_catname')

# Print the planet names
print(planet_names)
