Parameters

POST /companies takes the identical fields as a JSON body, which is easier when the condition array is long. `searchFields` accepts about.name and domain.domain. Always set an explicit small `size` — the default of 10 bills for 10 companies. GET /companies/count returns just the match count and is widely treated as free, though that is not published
