Why use this

Complete transaction history for one insider across all companies.

Common use case

Researching an insider like Elon Musk (CIK 1494730) — see all trades across TSLA, SpaceX, etc., with total shares owned per company.

Insider-scoped transaction history — one reporting person's complete trade tape across every issuer they file at. The natural lookup when a person/entity is the analyst's primary key (insider profile pages, activist-tracking dashboards, fund-manager activity feeds).

The path parameter expects a 10-character zero-padded CIK; shorter forms are auto-padded server-side. Returns HTTP 404 when the CIK cannot be resolved to any reporting owner. Use the ticker query parameter to narrow to a single-issuer history (e.g. 'all of Cook's AAPL trades') without falling back to /transactions/by-ticker.

The response carries a meta.insider block (cik / name / is_entity / total_companies) so UI page headers can render the insider profile without a second round-trip to GET /insider-module/api/insiders/insider/{insider_cik}. When dedup_owners=true, joint filings only surface for THIS insider if they were the deterministic winner of the dedup partition (lowest transaction_id); the surviving row carries the full co_owners array so the UI can show 'this trade was filed jointly by N entities'.

Parameters

Name	In	Required	Default	Allowed	Description	Example
cik	path	required	—	—	Insider CIK number	0000320193
limit	query	optional	50	—	Limit results	20
from_date	query	optional	—	—	Start date (YYYY-MM-DD)	2026-01-01
to_date	query	optional	—	—	End date (YYYY-MM-DD)	2026-04-01
dedup_owners	query	optional	false	—	Opt-in server-side joint-filer dedup. When true, the response only includes the canonical winner of each natural-key partition (deterministic by lowest transaction_id) and adds co_owners + co_owner_count. The insider only appears for a joint filing if they were the canonical winner. Default-path response shape unchanged.	true

data[].is_cashless_exercise	boolean	no	`true` for option-exercise-and-immediate-sale patterns.

data[].is_entity	boolean	yes	`true` for entity reporters.
data[].is_director	boolean	no	Director relationship to this issuer.

meta.pagination.has_more	boolean	no	`true` when another page is available.
