  Documented rate limits for the Buildxact Public API. Buildxact's gateway
  enforces a sliding-window cap of 100 HTTP requests per 30-second period
  per subscription key. Exceeding the limit returns HTTP 429.

responseCodes:
  throttled: 429
  quotaExceeded: 429
algorithm: sliding-window
limits:
  - tier: All Subscribers
    scope: per-subscription-key
    requests: 100
    period: 30s
    description: 100 requests in any rolling 30-second window across all endpoints.
notes:
  - Limits are enforced at the Azure API Management gateway layer.
  - Clients should back off on HTTP 429 and respect any Retry-After header.
  - OData paging ($top, $skip) lets clients chunk large result sets within the request budget.
