Does Polygon provide the filing date for any financial reports?

Yes, we provide 10K and 10Q financial reports for all US-based companies through our Stock Financials endpoint. We source this data directly from the SEC Edgar database. We’ve standardized annual and quarterly company filings into fundamental accounting concepts that are easy to use and compare across companies and industries. We include the filing date as well as the actual report in the “source_filing_url” link included in the response.
