Standard Datafeed client library for Python

Standard Datafeed client library for Python

The Standard DataFeed (SDF) Download API provides an alternative method for users to request and retrieve SDF packages (schemas & bundles). This service is not a direct replacement and does not have 100% feature parity with the Loader Application. This API provides an alternative for users who are unable to utilize the Loader application due to following reasons:

• Inability to install 3rd party executables due to Corporate Security policies
• Inability to utilize the Loader application due to limitations or restrictions with the environment used to consume Standard Datafeed
• Clients who are utilizing existing delivery method like FTP, who may want to use a more secured & modern solution

This API allows users to retrieve maximum of latest 30 days of data

Additional parameters are available to filter requests to get the exact files users are looking for.

QFL data is delivered through Content API & Bulk Data API (SDF API)

• Content API : Provides direct access to FactSet-hosted QFL data. Suitable for interactive, ad hoc QFL requests. Constraints on large extracts. Costs are based on consumption, i.e. more calls can result in more costs.
• Bulk Data API : Provides access to download locations of zip files for client download. Suitable for production processes within a client environment. Cost is based on the use case and fixed unless scope changes (same as other SDFs).

This Python package is automatically generated by the OpenAPI Generator project:

• API version: 1.2.0
• Package version: 0.21.10
• Build package: org.openapitools.codegen.languages.PythonClientCodegen

Requirements

• Python >= 3.7

Using Pandas

To convert an API response to a Pandas DataFrame, it is necessary to transform it first to a dictionary.

import pandas as pd

response_dict = api_response.to_dict()['data']

simple_json_response = pd.DataFrame(response_dict)
nested_json_response = pd.json_normalize(response_dict)

Debugging

The SDK uses the standard library logging module.

Setting debug to True on an instance of the Configuration class sets the log-level of related packages to DEBUG and enables additional logging in Pythons HTTP Client.

Note: This prints out sensitive information (e.g. the full request and response). Use with care.

import logging
import fds.sdk.StandardDatafeed

logging.basicConfig(level=logging.DEBUG)

configuration = fds.sdk.StandardDatafeed.Configuration(...)
configuration.debug = True

Configure a Proxy

You can pass proxy settings to the Configuration class:

• proxy: The URL of the proxy to use.
• proxy_headers: a dictionary to pass additional headers to the proxy (e.g. Proxy-Authorization).

import fds.sdk.StandardDatafeed

configuration = fds.sdk.StandardDatafeed.Configuration(
    # ...
    proxy="http://secret:password@localhost:5050",
    proxy_headers={
        "Custom-Proxy-Header": "Custom-Proxy-Header-Value"
    }
)

Custom SSL Certificate

TLS/SSL certificate verification can be configured with the following Configuration parameters:

• ssl_ca_cert: a path to the certificate to use for verification in PEM format.
• verify_ssl: setting this to False disables the verification of certificates. Disabling the verification is not recommended, but it might be useful during local development or testing.

import fds.sdk.StandardDatafeed

configuration = fds.sdk.StandardDatafeed.Configuration(
    # ...
    ssl_ca_cert='/path/to/ca.pem'
)

Notes for Large OpenAPI documents

If the OpenAPI document is large, imports in fds.sdk.StandardDatafeed.apis and fds.sdk.StandardDatafeed.models may fail with a RecursionError indicating the maximum recursion limit has been exceeded. In that case, there are a couple of solutions:

Solution 1: Use specific imports for apis and models like:

• from fds.sdk.StandardDatafeed.api.default_api import DefaultApi
• from fds.sdk.StandardDatafeed.model.pet import Pet

Solution 2: Before importing the package, adjust the maximum recursion limit as shown below:

import sys
sys.setrecursionlimit(1500)
import fds.sdk.StandardDatafeed
from fds.sdk.StandardDatafeed.apis import *
from fds.sdk.StandardDatafeed.models import *
