SEC filings API,
indexed by company and form.

What the SEC filings API returns

The index is read from SEC EDGAR's company submissions data for issuers with a U.S. listing. Each row is one filing, tied to the listing you asked for:

security_id repeats instrument_id and is being retired in its favor. Batch up to 100 symbols in one request; unresolved symbols are reported in meta.errors instead of failing the whole batch.

Common SEC filing queries

# Latest annual report
GET /v1/filings?symbols=XNAS:MSFT&forms=10-K&order=desc&limit=1

# Every 8-K a company filed in a quarter
GET /v1/filings?symbols=XNYS:JNJ&forms=8-K,8-K/A&from=2026-07-01&to=2026-09-30

# The 10-Q whose period of report falls in June 2026
GET /v1/filings?symbols=XNAS:AAPL&forms=10-Q&period_from=2026-06-01&period_to=2026-06-30

Linking filings to financial data

The accession number is the join key. As-reported facts in /v1/financials/facts carry the accession number of the filing they came from, so you can go from a 10-Q row to the XBRL values tagged in it, and from any fact back to its filing. To read the document itself, open it on SEC.gov by the same accession number. Normalized statements live in financial statements.

Filing text

/v1/filings/{filing_id}/sections returns the narrative text of 10-K and 8-K filings, amendments included: Business, Risk Factors and MD&A from a 10-K, and each item of an 8-K, such as 2.02 Results of Operations. Sections arrive the morning after the filing date and cover about two years of filings. Other forms are indexed but not parsed. /v1/filings/{filing_id}/exhibits lists each exhibit of a filing as its SEC EDGAR index names it, every indexed form included: the exhibit number (99.1, 10.1, 31.1), the filer's description and a link to the document on sec.gov, within about an hour of the filing being indexed and back about two years. Insider trades from Form 4 disclosures are structured separately in insider transactions.

Use cases

• Filing alerts: poll for new 8-K rows on a watchlist and notify when a company reports a material event.
• Earnings research: find the 10-Q or 10-K behind a quarter, then pull its XBRL facts by accession number.
• Audit trails that cite the exact filing a figure came from.
• Tracking amendments: an 8-K/A or 10-K/A row tells you an earlier filing was corrected.

Because each row keeps the ticker the listing had at the time, a filing from before a rename still resolves to the right company. Query by instrument_ids to follow a listing across ticker changes, or by symbols with symbol_at to ask what a ticker meant on a past date.

Point in time and history depth

as_of limits results to filings OHLC had recorded by the end of that UTC day. Recording started when OHLC indexed each filing, so an as_of earlier than that returns no rows rather than a reconstructed index. Depth varies by issuer: on October 3, 2026, Apple's index began with its filings from October 2024. Plan history limits also apply, at five years on Free and Developer and 15 on Pro.

Plans and credits

The filings index is included on every plan, Free through Scale; Free covers its seven tickers and Developer ($49/month) every U.S.-listed company. A request costs 50 credits regardless of how many symbols it carries, up to the 100-symbol batch limit. Use Developer or above for personal research and Commercial to show filings to your own users.
