Source & terms

The figures come from filings submitted to the U.S. Securities and Exchange Commission through EDGAR. The field mapping, derived values and split adjustments are calculated by Quotelinks and may differ from figures in the filings or from other data providers. Quotelinks is not affiliated with or endorsed by the SEC.

The API is provided for personal, non-commercial use. Redistribution of the data is not allowed. For commercial use, contact support@quotelinks.com. See the Terms of Service and the disclaimer. The figures are for information only and are not investment advice; check the original filing before relying on a number.

From filings submitted to the U.S. Securities and Exchange Commission: the SEC's XBRL company facts, company submissions and ticker files from EDGAR. Quotelinks maps the XBRL tags to 39 standard fields and calculates derived values such as Q4 and free cash flow.

Every night, from the SEC's latest bulk files. A new 10-K or 10-Q usually appears the day after the SEC publishes its data. The /v1/status endpoint shows the current build.

Yes, with basis=latest (the default): per-share values and share counts reported before a split are converted to today's share basis and flagged split_adjusted. basis=original returns the figures exactly as first reported.

The API uses the figures companies report under US GAAP or IFRS in their filings, not adjusted (non-GAAP) numbers or analyst estimates. Restatements, the choice of XBRL tag and fiscal-year labels can also differ between providers. The sources field shows the tag behind every value.

Yes. Every endpoint that takes a ticker also accepts the SEC CIK number, with or without leading zeros, for example /v1/company/320193 or /v1/company/0000320193.

No. It contains only data filed with the SEC: company information, financial statements and filings.

About 21,500 SEC registrants that have a ticker or file XBRL financial data, including OTC companies, with standardized financial statements for about 17,000 of them. Foreign companies that report under IFRS appear in their own currency. Companies that do not file with the SEC are not included.
