OpenAPI Specification

openapi: 3.2.0
info:
  title: Broadcastwell Public API
  version: 1.0.0
  summary: Read the answers five AI engines gave to your buyers' questions, with every receipt.
  description: 'Read only. Every rate is a five field object: pct, low, high, interval and base, where low and high are the 95% Wilson interval and base states the count. Every headline figure counts scheduled runs only. Adaptive runs are labelled and never pooled. Errors are problem details with a next step. Version 1 changes only by addition.


    The public demo key bwp_demo_kalvenor_sample reads the fictional Kalvenor sample at /accounts/sample.


    The separate commercial Agent Test is run by ChatGPT Work with Cloud browser, two runs per task at least two hours apart. Its ten task results and 20 session receipts are delivered through the owning account after human review; they are not pooled with the five-engine measurements described by this API.'
