About Chadwin

Chadwin provides financial data infrastructure for apps, websites, and agents. We help developers, investors, and researchers work with public company data without building and operating their own filing ingestion systems.

What Chadwin provides

Chadwin offers public-company lookup, annual and quarterly reports, insider ownership and transactions, proposed sale notices, institutional holdings, and real-time polling feeds for newly available filings. Customers can use the REST API, Node.js SDK, or hosted MCP server. Our guides describe the available datasets and integration options.

Source data

Chadwin derives its public-company data from filings submitted to the US Securities and Exchange Commission. Responses retain source details such as form types, filing dates, accession numbers, and filing links where they matter, so users can trace results back to the public record.

Company

Chadwin is operated by Chadwin AB, Swedish organization number 559525-6438, in Stockholm, Sweden.
