summary: >-
  The free tier's volume is published on the /info page as an approximate per-IP envelope across three
  windows; the paid tier is described only as "higher RPM" with no number. Exhaustion is a 429 whose JSON
  body may carry a machine-readable upgrade object; no rate-limit response header (RateLimit-*,
  X-RateLimit-*, Retry-After) is documented anywhere, and none was observed because robots.txt disallows
  /v1/ and the select route was not called.
