Text limit: 750 characters. Up to 40 Selling Points per Voice. Returns one result per requested element, in request order: the saved Selling Point, or the reason that element was not applied (access, plan cap, not found). Other elements are unaffected. Selling Points feed direct-message generation only — never comments. The change applies to future generations only: an existing DM draft keeps its text until it is refreshed (`dm-conversations_generate-or-improve-reply`). ## OpenAPI ````yaml https://api.goextrovert.com/client/v2/docs-json post /client/v2/voice-selling-points openapi: 3.1.0 info: title: Extrovert Client API description: >- Public API for Extrovert platform integration.
