# List filter values

`GET /api/v1/contacts/filter-values`

Authentication: API key.

Query param `field`, returns allowed enum values for list filters used in search. Supported fields: `seniority`, `job_functions`, `company_size`, `revenue`, `regions`, `continents`, `countries`, `headquarters_countries`, `office_countries`, `job_location_country`, `industries`, `personas`, `entity_types`, `email_status`. Free-text filters have no fixed value list, asking for one returns a `400` saying so.
