- Auth: None · pricing: Free · x402: no · licence: Public information. The SEC says information on sec.gov may be copied or further distributed without its permission, and asks for citation. EDGAR names and logos are registered trademarks
- Probe metrics: not measured yet (probes haven't run)
- API: Four GET routes on `https://data.sec.gov` returning JSON. `submissions/CIK##########.json`, `api/xbrl/companyconcept/CIK##########/{taxonomy}/{tag}.json`, `api/xbrl/companyfacts/CIK##########.json` and `api/xbrl/frames/{taxonomy}/{tag}/{unit}/{period}.json`. No query parameters
- Coverage: Filing history for every EDGAR filer, with name, former names, tickers, exchanges, SIC code and addresses. XBRL facts from forms 10-Q, 10-K, 8-K, 20-F, 40-F and 6-K in standard taxonomies such as us-gaap, ifrs-full, dei and srt
- Rate limits: 10 requests a second for each user across all machines. Over it, further requests from the IP address may be limited until the rate has stayed below the threshold for 10 minutes
- Credentials: None. A User-Agent header with an organisation name and contact email address is requested of automated callers
- Response size: No limit, paging or field selection. Submissions hold at least a year or 1,000 of the most recent filings in column arrays, with older filings in extra files listed under `filings.files`. On 9 October 2026 Apple's submissions file was 164 KB (28 KB gzipped) and one company concept 19 KB
- Frames: One fact for each reporting entity for a period written `CY2019` (annual), `CY2019Q1` (quarterly) or `CY2019Q1I` (instantaneous). Units with a denominator are written with `-per-`, such as `USD-per-shares`
- Errors: Not documented. A request for a path that does not exist on data.sec.gov answered 404 with an XML body carrying the code `NoSuchKey`
- Bulk data: `companyfacts.zip` and `submissions.zip`, rebuilt nightly at about 3:00 a.m. ET. EDGAR index files and daily archives sit under `https://www.sec.gov/Archives/edgar/`

## Before you call it

1. Send a User-Agent naming the operator's organisation and a contact email address on every request. The SEC limits or blocks undeclared automated tools
2. Stay under 10 requests a second in total across all machines. Over the limit, the IP address may be limited until the rate has stayed below the threshold for 10 minutes
3. Pad the CIK to 10 digits with leading zeros in `submissions/CIK##########.json` and the XBRL paths. Find a CIK in `https://www.sec.gov/files/company_tickers.json`
4. Prefer `api/xbrl/companyconcept/` for one figure. `companyfacts` returns every concept a company has reported, and `submissions` returns at least 1,000 filings in column arrays
5. Read older filings from the extra files named in `filings.files`, and check a frame fact's own start and end dates, since frames align company periods to calendar quarters

## Connect

```bash
curl -H "User-Agent: $ORG_NAME $CONTACT_EMAIL" https://data.sec.gov/submissions/CIK0000320193.json
