  - name: Standard Request Limit

  - name: Burst Limit
    description: Additional requests permitted on top of the standard per-second limit to absorb short traffic spikes.
    scope: per-account
    rate: 100
    period: second

errors:
  - code: 429
    message: Too Many Requests
    description: Returned when the rate limit is exceeded. Clients should implement exponential backoff retry logic and reduce request volume when this status code is received.
handling:
  strategy: exponential-backoff
  description: Watch for 429 status codes and implement a retry mechanism using exponential backoff to reduce request volume progressively until requests succeed.
