Rules for this host — https://free.officemaker.ai (free tier)

No API key and no Authorization header on REST (/gpt/v1/) or MCP (/mcp).
Public internet — do not send secrets, regulated health data, or confidential client material; outputs may be ad-supported.
Not a substitute for the authenticated service: conversion, assembly, billing, and full enterprise APIs live on https://docs.officemaker.ai (and the internal docs host for staff).
Use Start here and the doc tabs above; treat https://free.officemaker.ai as a sandbox for experiments and demos.
