  No rate limits are published for the Sensors Data OpenAPI. The overview, authentication
  and interface manual pages state nothing about QPS, request quotas, burst allowances or
  throttling behaviour, and none of the 252 published operations documents a 429 response
  or any X-RateLimit-* / RateLimit-* / Retry-After header. This is consistent with the
  delivery model: the API runs inside the customer's own cluster, so throughput is bounded
  by the capacity the customer bought rather than by a vendor-published quota.
quota_endpoints:
  note: >-
    What Sensors Data DOES ship is the inverse of a rate-limit header — explicit
    quota-read operations that let a client check its own headroom BEFORE it writes. These
    are business-resource quotas (how many attributes/audiences/tags a project may hold),
    not request-rate quotas.
  operations:
    - operationId: QueryQuota
      method: GET
      path: /express-attribute/quota/query
      spec: openapi/sensors-data-focus-express-attribute-v1-openapi.yml

      method: GET
      path: /express-audience-meta/quota/query
      spec: openapi/sensors-data-focus-express-audience-meta-v1-openapi.yml

documented_throughput_guidance:
  - surface: Sensors Focus webhook delivery
    statement: >-
      "Webhook itself makes no timeliness guarantee." Triggers are micro-batched into a
      single request to raise throughput, which introduces several seconds of latency.
      High-volume batch plans and sub-second requirements are both directed to sales
      engineering rather than to a documented limit.
