EDGAR Online is a service that provides data related to equities, mutual funds and public assets. With the API, developers could retrieve financial information from an individual, search financial content of a company and even complete targeted searches in multiple locations. The API is about financial data and it may be useful for developers in the financial sector who intent to have access to financial public information. To create an application, developers can register for an API key. At the same time, they can review the datasets along with actions and description for different parameters such as companies, coreFinancials and CompanySets. Just as the API Key is required, also is the protocol HTTPS, endpoints and responses in JSON/XML formats.
