description: Broadridge does not publish API rate limits on a public developer portal. The Wealth Management,
  Galaxia Fund Data, and Investor Communications APIs are accessed by contracted customers; rate-limit
  terms are conveyed in the platform contract and onboarding documents. Consumers should expect HTTP
  429 throttling on overuse and apply exponential backoff.

notes: Per-API rate limits are not publicly published; values are contract / onboarding specific.

  - name: Backoff Strategy
    description: Apply exponential backoff with jitter on 429 / 503 responses; honor Retry-After when
      present.
  - name: Contract-Bound Capacity
    description: Effective request capacity is set by the platform contract and partner onboarding documents,
      not via a public tier page.
  - name: Batch-Oriented Processing
    description: Many Broadridge data feeds (positions, transactions, fund data) are intentionally batch-oriented;
      align integration design with the documented file / API cadence rather than driving high-frequency
      polling.
  - name: Fair Use
    description: Sustained traffic that materially impacts shared infrastructure may trigger throttling
      regardless of contract.
