Quarterly ownership data.
Source records intact.

The SEC’s quarterly Form 3/4/5 archive contains submission, reporting-owner, transaction, holding, footnote and signature tables. This API exposes its derivative and nonderivative transaction tables with linked filing context and referenced footnotes.

Verified imported coverage

The completed 2026 Q3 import contains 38,152 submissions, 59,885 nonderivative transaction rows and 19,205 derivative transaction rows: 79,090 transaction records available through this endpoint. The broader stored archive also includes holdings, owners and signatures that this route does not expose.

Archive SHA-256: a4e6a681cfcfa43a3d9e4ca9cfec1fd26a59d0a01eac7e9f7b5a0122092c90f3. These counts describe one imported vintage, not historical market-wide coverage.

Query a page

curl --fail-with-body "https://sec-api.dev/api/v1/insider-transactions?period=2026q3&limit=100" \
  -H "Authorization: Bearer $SEC_API_KEY" -o insider-page.json

The result is one JSON page. Follow pagination.nextOffset, not an assumed fixed page length. pagination.total counts matching transaction rows, not unique submissions, people or executed trades. Filter cik by issuer. Account request quotas apply.

Quality diagnostics are part of the dataset

The importer preserves source TSV names and exposes recognized metadata discrepancies through meta.quality. Nine duplicate signature keys in the upstream archive are retained as separate source rows; signatures are not returned by this transaction API. The import checked 175,026 footnote references and found zero unresolved references; three recognized source metadata discrepancies are recorded in the response diagnostics. These checks do not verify the economic truth of the disclosures.

Use the source representation

Amounts, quantities, dates and flags remain source strings. filingDateReported uses the source’s DD-MON-YYYY representation. Read footnotes before interpreting transaction codes, prices or ownership changes. Amendment records are not consolidated into a revised trade history. This archive does not provide every disclosure field or establish the accuracy of filer assertions.
