    # valueUsd is null when the filing states no price; priceNote then says so (it also marks a price given as a range)

Form 4 is due within two business days of the trade; txDate is the trade date, not the filing date.

What people build with it

Response shape

Every endpoint returns the same JSON envelope: { data, updatedAt, source, docs, license, attribution, meta }. In meta, source names who publishes the data and sourceAttribution is the credit line to show with it. The data field is an array of records with these fields:

Query params: type=buys or sells (default buys; S and sales also mean sales), window=7d, 30d or 90d (default 30d). Returns up to 100 open-market transactions, newest first. The per-ticker endpoint returns { ticker, transactions } with the same record fields plus txCode and isOpenMarket.

Numeric fields typed string in the table carry exact decimals; parse them with your language's decimal type. No key needed to start: 10 requests a minute per IP without a key and 30 a minute with a free account key, with at least six months of history. A 429 response carries a Retry-After header in seconds. Credit XOOMAR with a link to the dataset page when you republish the data; the data terms are on the terms page.

A free account key raises the limit; send it in an X-API-Key header.

/api/markets/insiders/clusters: days 1 to 365 (default 30), minInsiders 2 to 20 (default 3), minUsd (default 0), ticker, limit up to 500 (default 100). Companies where at least minInsiders different insiders bought on the open market (Form 4 code P) within the window; awards, option exercises and plan purchases are not buys. Built from the Form 4 rows above, so a company appears the same day its filings do.
