Introduction

API Reference

The Fiddler API contains many useful tools for sending and receiving data to and from the Fiddler platform.

Fiddler provides a Python SDK client that allows you to connect to Fiddler directly from a Jupyter notebook or automated pipeline.

Each API is documented with a description, usage information, and code examples.

Client Setup

`fdl.FiddlerApi`

The API client object used to communicate with Fiddler.

In order to use the client, you'll need to provide authentication details as shown below.

For more information, see Authorizing the Client.

import fiddler as fdl

URL = 'https://app.fiddler.ai'
ORG_ID = 'my_org'
AUTH_TOKEN = 'p9uqlkKz1zAA3KAU8kiB6zJkXiQoqFgkUgEa1sv4u58'

client = fdl.FiddlerApi(
    url=URL,
    org_id=ORG_ID,
    auth_token=AUTH_TOKEN
)

proxies = {
    'http' : 'http://proxy.example.com:1234',
    'https': 'https://proxy.example.com:5678'
}

Parameters

Parameter	Type	Default	Description
`url`	`str`	`None`	The URL used to connect to Fiddler.
`org_id`	`str`	`None`	The organization ID for a Fiddler instance. Can be found on the General tab of the Settings page.
`auth_token`	`str`	`None`	The authorization token used to authenticate with Fiddler. Can be found on the Credentials tab of the Settings page.
`proxies`	`Optional[dict]`	`None`	A dictionary containing proxy URLs.
`verbose`	`Optional[bool]`	`False`	If `True`, API calls will be logged verbosely.

Warning: If verbose is set to True, all information required for debugging will be logged, including the authorization token.

To maximize compatibility, please ensure that your client version matches the server version for your Fiddler instance.

When you connect to Fiddler using the code on the right, you'll receive a notification if there is a version mismatch between the client and server.

You can install a specific version of fiddler-client using pip:
pip3 install fiddler-client==X.X.X

%%writefile fiddler.ini

[FIDDLER]
url = https://app.fiddler.ai
org_id = my_org
auth_token = p9uqlkKz1zAA3KAU8kiB6zJkXiQoqFgkUgEa1sv4u58

If you want to authenticate with Fiddler without passing this information directly into the function call, you can store it in a file named fiddler.ini, which should be stored in the same directory as your notebook or script.

client = fdl.FiddlerApi()

Projects

Projects are used to organize your models and datasets. Each project can represent a machine learning task (e.g. predicting house prices, assessing creditworthiness, or detecting fraud).

A project can contain one or more models (e.g. lin_reg_house_predict, random_forest_house_predict).
