FactSet Formula API

FactSet’s Formula API is a modern, flexible, formula-based API that enables users to access FactSet’s wide range of financial data and content. The API offers two endpoints, one optimized for time-series analysis and one designed for cross-sectional analysis, providing users a simplified interface into FactSet’s expansive offering. By providing two endpoints, it allows for the optimization of user workflows, while reducing complexity.

Leverage the power and flexibility of the Formula API to -

• Pull data from across most content sets that a user has access to in a single request
• Include business logic and mathematical operations in request
• Submit a dynamic universe in both endpoints
• Return the fsymId to easily combine with other FactSet content / products
• Set the trading calendar
• Define custom display names

Formula API Request Builder

The Formula API Request Builder provides users everything they need to form a Formula API request. In the Request Builder, you can select identifiers, build a universe expression, select FQL or Screening formulas, easily apply business logic and mathematical functions to the FQL or Screening formulas, specify optional parameters, and construct a GET or POST request. The Request Builder eliminates the need to have previous FQL and Screening knowledge and allows you to quickly find your desired data items and form the request.

The Formula API Request Builder can be accessed by navigating to https://developer.factset.com/formula-api-request-builder and logging in using your FactSet.net ID. When using the Request Builder to construct requests for the one of the Formula API's endpoints, be sure to toggle to the correct endpoint at the top of the page.

How to Check the Health and Availability of the Formula API

Please use the below endpoint to check the health and availability of the Formula API. You must be authorized for this API to use the Health endpoint.

How to Programmatically Download API Specification File

Please use the below endpoint to download the FactSet Formula API Specification File in .yaml. You must be authorized for this API to extract. This specification can then be used for Codegen to create your own SDKs. You can also download the spec using the "Download Spec" button to the right of the version number.

Notes for Large OpenAPI documents

If the OpenAPI document is large, imports in fds.sdk.Formula.apis and fds.sdk.Formula.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.Formula.api.default_api import DefaultApi
• from fds.sdk.Formula.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.Formula
from fds.sdk.Formula.apis import *
from fds.sdk.Formula.models import *
