SEC data for investment managers

Use this guide to reproduce the evidence section of a research note, such as an issuer brief or position-change review. SEC API supplies documented data routes; your team retains responsibility for methodology, investment decisions, and portfolio action.

Choose the evidence stream

Research job	Route	Decision criterion
Resolve the issuer before research	`GET /v1/entities/resolve`	Ticker, CIK, and the downstream identifier are correct.
Retrieve the filing record behind a claim	`GET /v1/filings`	Form, filing date, accession number, and filing URL are retained.
Review a manager’s 13F filing	`GET /v1/owners/13f` or `POST /v1/owners/13f/compare`	The manager filer CIK and reporting period are explicit.
Review issuer-level holders	`GET /v1/owners/institutional/ticker`	The issuer and returned coverage fit the question.
Describe factor exposure	`GET /v1/factors/exposures`	Symbols, model inputs, and returned methodology or trust fields are retained.
Review insider activity	`GET /v1/insiders`	Form family, transaction dates, and source fields meet the review policy.

Manager-level 13F holdings and issuer-level institutional holders answer different questions. Do not use a manager CIK query as an issuer-holder lookup, or infer conviction from a 13F or Form 4 result.

Test an ownership question

curl --fail-with-body -sS \
  -H "x-api-key: $SECAPI_API_KEY" \
  "https://api.secapi.ai/v1/owners/13f?cik=0001067983&limit=20"

curl --fail-with-body -sS \
  -H "x-api-key: $SECAPI_API_KEY" \
  "https://api.secapi.ai/v1/owners/institutional/ticker?ticker=AAPL&limit=25"

Then retrieve an independent issuer evidence stream before describing the position:

curl --fail-with-body -sS \
  -H "x-api-key: $SECAPI_API_KEY" \
  "https://api.secapi.ai/v1/filings?ticker=AAPL&forms=10-K,10-Q,8-K&limit=10"

Separate research from judgment

Factor exposure is descriptive, not a forecast. Ownership disclosures are time-bound filings, not proof of current intent. Preserve returned filing IDs, dates, source URLs, requestId, and any freshness or warning fields, then make any investment interpretation in your own documented process.
