description: >-
  Quix does not publish a fixed numeric rate-limit table for its HTTP and
  SignalR APIs. The practical throughput of the Streaming Writer API (HTTP),
  Streaming Reader API (SignalR/WebSocket), and Portal API is bounded by the
  capacity of the underlying managed Kafka and Kubernetes resources provisioned
  for your Quix Cloud environment rather than by a per-key request quota.
  Authentication uses Personal Access Tokens (PATs); expired or invalid tokens
  return HTTP 401 (or an UnAuthorizedHubError on the SignalR hub).
notes: >-
  Confirm any environment- or account-level throttling, connection caps, or
  message-size limits in the per-environment Swagger reference and Quix support
  channels during reconciliation. The open source Quix Streams library is not
  rate limited by Quix; its throughput is governed by your own Kafka cluster.

responseCodes:
  unauthorized: 401
limits:
- name: Streaming Writer API Throughput
  scope: environment
  metric: requests
  limit: see provider documentation
  notes: >-
    HTTP ingest throughput is bounded by the managed Kafka / compute capacity of
    the environment, not a published per-key quota.
- name: Streaming Reader API Connections
  scope: environment
  metric: connections
  limit: see provider documentation
  notes: >-
    Concurrent SignalR (WebSocket) hub connections and subscriptions scale with
    the environment's provisioned resources.
- name: Portal API Requests
  scope: account
  metric: requests
  limit: see provider documentation
  notes: Account-wide management API; no fixed public request quota published.
policies:
- name: Token Authentication
  description: >-
    All API access requires a valid PAT bearer token; expired/invalid tokens
    return 401 (HTTP) or UnAuthorizedHubError (SignalR).
- name: Capacity-Bound Throughput
  description: >-
    Throughput scales with the managed Kafka and Kubernetes resources of the
    Quix Cloud environment rather than a per-key rate limit.
- name: Backoff Strategy
  description: >-
    Clients should implement retries with exponential backoff and reconnect
    logic for the SignalR hub.
