description: >-
  Voltus publishes no rate-limit documentation page, but every response carries
  IETF-style x-ratelimit-* headers. The values below were read directly off live
  responses; the window is not stated by Voltus, and x-ratelimit-reset counts up
  with each request within the window rather than reporting a reset timestamp.
  Recorded as observed, not as a Voltus commitment.
headers:
  limit: x-ratelimit-limit
  remaining: x-ratelimit-remaining
  reset: x-ratelimit-reset
