Free to call and never fetches a row, so a builder can draw the table header before any preview is bought. A column that no added lead fills is left out when the table is created; a preview, which has leads in hand, lists only the columns they fill. Buying-signal searches take the chosen signal as `signal_type`, which adds the columns that signal's own details earn. ## OpenAPI ````yaml /openapi.json get /find-leads/columns/ openapi: 3.1.0 info: contact: email: support@getoneprofile.ai name: Oneprofile Support description: >- REST API reference for Oneprofile, the GTM data layer for your CRM.
