Pollfish Respondent Demographics API

openapi: 3.0.3
info:
  title: Pollfish API
  version: '2026.07'
  description: >-
    Unified OpenAPI description of Pollfish's documented public REST surfaces.
    Pollfish is a mobile survey and market-research platform owned by Prodege LLC.


    Two hosts are covered:

    - `https://www.pollfish.com` - the Dashboard API (publisher app management and
      analytics), HTTP Basic Auth with your Pollfish account email and secret key.
    - `https://wss.pollfish.com` - the survey-serving / offerwall API used as an
      alternative to the SDK. Despite the `wss` hostname, the transport is HTTPS
      GET/HEAD, NOT WebSocket.


    Endpoints are annotated with `x-endpoint-status` of `confirmed` (documented in
    Pollfish's own GitHub docs at github.com/pollfish/docs) or `modeled` (shape
    inferred where the response body is HTML or the schema is not exhaustively
    documented). Survey creation / audience design for researchers is done in the
    Pollfish dashboard and is not part of this documented public REST API.
