description: Published rate limits for the Sovrn Commerce (formerly VigLink) APIs.
  Reporting APIs are limited to 1 request every 60 seconds; the Merchant Group
  Summaries APIs to 1 request every 10 seconds. Exceeding limits may result in an
  API key being temporarily blocked or throttled; 429 responses are documented on
  the Merchant Summaries API.

  allow higher throughput, often supporting multiple requests per second depending
  on the endpoint (per the Commerce MCP documentation).
- Limits are per tool/endpoint, not global across the Commerce API surface.
