Turn your data into an API

1. In Workbench create a new UDF that returns data, for example:

@fused.udf
def udf(path: str = "s3://fused-sample/demo_data/housing/housing_2024.csv"):
    import pandas as pd
    housing = pd.read_csv(path)
    housing['price_per_area'] = round(housing['price'] / housing['area'], 2)
    
    return housing[['price', 'price_per_area']]

UDF Editor

1. Click "Share" to open your UDF in a new Tab as a HTML Page
2. Optionally: Edit the URL to return the data in your preferred file format.

For example changing the format from parquet to json:

# Returning as JSON

# Returning as CSV
https://fused.io/.../run/file?format=csv

Optionally: Edit the URL to return the data in your preferred file format.
