  title: GPT-5.5 Local for API.market Utility Tools API
  version: 1.0.0
  description: Ordinary REST wrapper for deterministic developer utilities intended for API.market source import. These endpoints do not call an LLM, do not spend upstream tokens, and do not fetch arbitrary remote URLs. Commercial access, subscriber authentication, quotas, and billing should be configured in API.market.
  x-api-market-positioning: Use this API Source for low-risk deterministic tools with near-zero upstream cost. LLM chat and web-fetch tools are intentionally excluded from this API.market wrapper.
