Masterminds HQ API Docs

Last updated 29 October 2026

Public, read-only API for Joe Che's Masterminds HQ. Agents use it to list current offers with prices, look up one offer, and search published answers to common questions. No authentication is required. Nothing here charges a card: every offer links to its hosted checkout, which the buyer completes. Rate limit: 60 requests a minute per client, reported in RateLimit headers. Versioning: the major version is in the path; breaking changes ship as a new version and the old one keeps working for at least 90 days after a Deprecation and Sunset header announce it. Lists use cursor pagination (limit, cursor, next_cursor). Base URL: https://mastermindshq.business/api/v1. Getting started, the sandbox and the MCP server are on the developer portal. The same reference is available as OpenAPI 3.1 JSON.

Authentication

None. The API is public and read-only. No API key is needed.
