Profitero Rate Limits

Profitero publishes no API rate limits, because it publishes no API reference. An API demonstrably EXISTS — Profitero's own CEO says so on the company blog: "Technology partners, like Kenshoo and Pacvue, will be able to integrate directly with Profitero via API and use the data to power their ad buying algorithms and software", and "We will also consider providing API access to agencies in Q4" (Bryan Wiener, Open Commerce Ecosystem Q&A, 2020-09-09, HTTP 200). But no base URL, authentication model, operation list, quota, window, burst allowance, response header or exhaustion status code for it is published on any public host. Contract discovery was run against every reachable host: api.profitero.com, developer.profitero.com and developers.profitero.com do not resolve (NXDOMAIN); www.profitero.com hard-404s /openapi.json, /swagger.json, /api-docs, /graphql, /mcp and /llms.txt; app.profitero.com 301s every path to /login.html; sso.profitero.com is an SPA catch-all that answers 200 with the same 450-byte shell for every path; docs.profitero.com 302s to an internal Google Drive workspace; and help.profitero.com is a PRIVATE Zendesk Help Center whose article API returns HTTP 401 "Couldn't authenticate you". Recorded as an honest zero, not an omission.
