name: StorONE S1 REST API rate limits
description: >-
  StorONE documents no rate limits for the S1 REST API, and this is a case where the absence is
  structurally correct rather than an oversight. The API is served by the customer's own controller
  nodes to the customer's own operators — there is no shared multi-tenant capacity to protect and no
  billing meter to enforce, so there is nobody to throttle. What that means for an agent is the
  reverse of the usual risk: nothing will stop a runaway polling loop except the storage
  controller's own CPU, and the controller is also serving production I/O.
limit_count: 0
limits: []
response_headers:
  documented: []
  note: >-
    No X-RateLimit-*, RateLimit-* or Retry-After header is documented on any response. There is no
    runtime signal an agent can back off on.
exhaustion_status: null
exhaustion_note: >-
  429 does not appear on any of the 164 documented operations. The only documented failure codes are
  400 and, on login, 401.
timeouts:
  observed: >-
    A `limit` parameter appears on at least one operation as an operation timeout — "Set limit for
    the operation (by default it is set to 10 seconds)" — which is a per-call deadline, not a rate
    limit.
session_limits:
  inactivity_timeout: >-
    The caller sets InactivityTimeoutInMinutes on POST /login. That is the only published throttle
    on API use, and it governs session lifetime rather than request rate.
agent_guidance: >-
  Poll the monitoring endpoints conservatively. GET /monitoring/performance/live,
  /monitoring/utilization/live and /monitoring/health/current are the obvious candidates for a tight
  loop, and they run on the same controllers that serve host I/O. Prefer the /history variants for
  trend data and treat the live endpoints as on-demand.
