Overview
Returns the detail tier for a single law firm: name, canonical name, country, aliases, attorney count, trademark count, active count, grant rate, and latest filing date. Optional?include=attorneys embeds the firm’s attorneys.
Recent changes
?include=stats has been removed (beta breaking change). Firm counts remain always-on top-level fields, including the new active_count field.
If the firm record was merged into another (entity resolution), the endpoint returns 410 entity_merged with the new ID in the error body.
