List columns

GET/contacts/schema

Returns every public column with its format, and every filter key with its type and its value route. Top-level job fields (title, company, company_domain, function, seniority, role_since) describe the main role. experience lists the person's current roles only, main role first; the source has no past roles. A housekeeping date (`last_updated`, `last_refreshed`) carries the month. A role start date (`role_since`) carries the day, because a job-change signal is only worth acting on when you know the day it happened. Free.
