EDGAR's full-text search covers electronic filings since 2001 and can be accessed for free via the efts.sec.gov full-text search interface or the data.sec.gov structured data API, with no API key required, but there are rate limits (typically no more than 10 requests per second) and a User-Agent declaration requirement.

The U.S. SEC requires all EDGAR filings to be submitted in XBRL format, and each XBRL filing comes with a FilingSummary.xml that lists all rendered R files, with each R file corresponding to a specific statement.

For EDGAR filings, page classification information is already fully provided by structured metadata, so there is no need to call an LLM to judge "is this an income statement?" for each page.
