API Reference

Open Data Initiative for Financial Data

Open Data

The Deep Audit API is an open data initiative that enables publicly available company financial data to be easily accessible. Using open data standards and a cloud-based application programming interface (API), anyone can retrieve detailed financial information from over 20,000 companies.

Data is extracted from corporate financial reports filed with the Securities and Exchange Commission using XBRL. The information is provided "as filed" and has not been verified for accuracy.

The data is meant to be used by a wide variety of interested parties, such as:

  • Investors
    Use the financial data to determine the strength of a company's finances and compare financial ratios with industry peers.
  • Companies
    Access the financial statements of your competitors to determine your competitive strengths and weaknesses.
  • Auditors
    Discover accounting descrepencies and compare data to other companies in the same industry.
  • Government Agencies
    Obtain industry-wide company statistics and compare numbers over multiple time periods.

The best part.. it's free
If you're looking to pay for public data, there are a number of providers more than happy to assist you. Since this is an open data project, there is no charge for accessing the Deep Audit API, but there are rate limits in place to ensure everyone has consistent access to the service.


The Deep Audit API is based on REST. An application key is required to access the API and it can be obtained by contacting us. Responses from the API are returned in either JSON or XML formats, depending on your preference.

Once signed up, you will have full access to all of our company information and financial data. To ensure stable access for all users, there is a default rate limit in place, but the limits can be increased to suit your needs.


All API requests must be made over HTTPS, since any calls made over HTTP will return an error. Authentication must be made for all calls and must include both your assigned username and authentication key. Be sure not to expose your authentiction key in any publicly accessible code.

To authenticate your request, you can either specify an Authorization header or pass the username/api_key combination as GET/POST parameters.

# As a header
# Format is ``Authorization: ApiKey :
Authorization: ApiKey daniel:204db7bcfafb2deb7506b89eb3b9b715b09905c8

# As GET params

Rate Limit

Eash authorization key is limited to 500 requests per hour. Once this limit has been exceeded, an error will be returned. If you find yourself reaching the limit, please contact us and we will do our best to accomodate your needs.
