Filters

ticker	Stock symbol, e.g. `AAPL`. Case-insensitive.
company_cik	SEC CIK (10-digit, zero-padded), alternative to ticker.
officer_name	Full or partial insider name; case-insensitive substring.
transaction_type	`buy` or `sell`.
transaction_codes	OR-filter on raw SEC codes, `['P']` open-market buys, `['S']` sales, `['M']` option exercises.
is_derivative	`true` for options / RSUs / warrants, `false` for common-stock rows.
min_value	Only trades with `total_value` ≥ this amount (USD).
include_unpriced	With `min_value` only: also keep rows where the insider stated no price (their `total_value` is null, so judge them on shares). Default false. `bulk_v2` only.
aff10b5one	10b5-1 trading-plan flag, `'1'` = plan adopted, `'0'` = none.
since / until	ISO dates (`YYYY-MM-DD`) bounding the window, on the `sort_by` date field.
sort_by	`disclosure_date` (default), `transaction_date`, or `total_value` (legacy only).
sort_order	`desc` (default) or `asc`.
limit	Maximum records to return. Default 50, max 500.
cursor	Pass the previous response's `next_cursor` verbatim to read the next page. Keep `sort_by` and `sort_order` the same across pages.
include_baseline	Also return matching Form 3 initial-ownership baselines.
merge_co_reports	Default true: when a fund, its general partner and the person in control each file a Form 4 for the same purchase, they are merged into one row. Set false for one row per filing (totals then double-count).
include_non_open_market	Include gifts, transfers, conversions, and tax-withholding events alongside open-market trades.
data_source	`bulk_v2` (default, full SEC bulk corpus) or the legacy collection.
reporting_owner_cik	Reporting owner CIK (10-digit, zero-padded). `bulk_v2` only.
reporting_owner_name	Reporting owner name substring, case-insensitive. `bulk_v2` only. Anchor it with `ticker`, `company_cik` or `reporting_owner_cik` to search full history; on its own it scans only recent filings.
row_type	`nonderiv` (direct common-stock activity) or `deriv` (options, RSUs, warrants). `bulk_v2` only.
trans_codes	The `bulk_v2` spelling of `transaction_codes`: same codes, same OR-filter, max 30.
schema_era	`pre_2023` (filed 2006 to 2022) or `2023_plus` (filed 2023 on, with the 10b5-1 flag). Driven by filing quarter. `bulk_v2` only.

Advanced (bulk_v2) filters: reporting_owner_name, reporting_owner_cik, row_type, trans_codes, schema_era, plus sort_by / sort_order / limit, see the OpenAPI spec.
