Understanding Data Sources
What is an OAM?#
All financial data available through the FinancialReports API is collected directly from Officially Appointed Mechanisms (OAMs).An OAM is the official term used throughout Europe for a national database that stores regulated financial information. Each member state of the European Union has its own OAM, which serves as the mechanism for companies to submit their financial reports to the relevant national regulatory authority. The system is part of the framework managed by ESMA (European Securities and Markets Authority).
Our Data Sources#
The API provides access to filings from OAMs across the European Union. These are the official, primary sources for corporate financial reporting.The entity that operates the OAM varies by country; it can be a national competent authority, a stock exchange, or even a private entity. For example, in Germany, the OAM is the Unternehmensregister (Company Register), while in many other countries it is operated by the national Competent Authority or the local Stock Exchange.

You can retrieve a complete list of all OAMs we source data from by making a GET request to the /sources/ endpoint. The response for each source includes its name, homepage url, and a brief description.A successful request to GET /sources/ will return a paginated list of source objects.{
