info:
  title: IA Selecta HTTP surfaces MCP API
  version: 1.20.0
  summary: Machine-readable map of the real HTTP endpoints on iaselecta.com.
  description: 'IA Selecta is served from this origin. Query the catalog through the MCP endpoint documented here — there is no parallel REST catalog. Unknown /api paths return JSON { error, status }. Public HTML pages also speak markdown at the same URL (Accept: text/markdown). Rate limit: 120 requests / 60s (IETF RateLimit + RateLimit-Policy; Retry-After on 429). URL path /api/v1 is the current catalog JSON. Responses also send API-Version: 1. Breaking changes ship under /api/v2. Deprecated versions get Deprecation and Sunset headers for at least 90 days. There is no v2 yet.'
