Guides
How Alpha Analyst ingests SEC filings, flattens XBRL, resolves companies, and translates EDINET — the pipelines behind the API.
These guides explain how production data is built, not every request parameter. Use them when you want intuition for freshness, chunking, identifiers, or why an empty XBRL axis means “consolidated.” Endpoint tables live in the API reference.
Turning SEC filings into markdown
Watch EDGAR, unpack SGML, HTML to markdown, header-aware chunks.
XBRL from the same filing
IDEA zip vs the HTML 10-K. Empty axes are consolidated.
Company resolution
Tickers, CIK, LEI, FIGI as a weighted graph. Fund isolation, argMax.
Translating EDINET filings at scale
FSA packages, ja→en, same chunker as SEC.
