}Filing detail
One listed document. By default the document itself: an SEC filing’s primary document as sanitized HTML, or a source document’s stored PDF, HTML, announcement, package or media (accession = the SEC accession or the document reference as the filings index lists it, e.g. DFM-EMAAR-2026Q2-FS). With format=text, its text as JSON: { document: { id, cik, title, form, type, date, source_url, pages, part, slides? }, parts? (SEC: the submission's readable documents), text_source (html | sgml_text | json | pdf_extracted | stored_extraction | ocr), stored_as?, page_from, page_to, pages_in_text, pages_without_text?, text, offset, next_offset, total_chars, truncated?, note?, source }. Paged documents mark each page “[page N]” (the PDF page, the filing’s own HTML page breaks, or the slide). A document with no text to read (slide images, an un-OCR’d scan, a recording) answers 200 with text: null and text_unavailable: { reason, detail, page_images?, document_route }; text is never reconstructed.

}Authorizations
Astreus API key (pk_live_...), created on the Developers page in the terminal. Also accepted as Authorization: Bearer pk_live_....
Path Parameters
Ticker symbol (e.g. NVDA), numeric SEC CIK (zero-padding optional), or the platform key of a non-SEC issuer (e.g. XSAU000001 — the cik field of the company payload). A bare ticker always resolves to the SEC registrant.
SEC accession number (0001045810-25-000023) or source-document reference (EMAARIR-2026Q2-PRES), as the filings index lists it.
Query Parameters
text = the document's text as paged JSON (see above); omit for the document itself.
text format=text, SEC filings: one document of the submission by its type (EX-99.1) or file name, from parts; default the primary document.
format=text: first page to read (paged documents).
1 <= x <= 5000format=text: last page to read (default the last).
1 <= x <= 5000format=text: character offset into the selected pages; the previous next_offset.
x >= 0format=text: characters to return, 1,000–200,000.
1000 <= x <= 200000Response
OK
The document as sanitized HTML.
