costOptimization:
  - recommendation: Use the Snapshot API for bulk data ingestion instead of making thousands of individual On-demand API requests. Snapshots are compressed and more data-efficient.
    impact: high
  - recommendation: Cache On-demand API responses locally to avoid re-fetching unchanged content. Wikimedia content changes infrequently for most articles.
    impact: high
  - recommendation: Request only the language editions and dataset types you need. The Enterprise API covers 360+ languages; limiting scope reduces egress costs.
    impact: medium
  - recommendation: Use the free tier for development and testing. Switch to a paid plan only when production volume exceeds the 50,000 monthly On-demand request cap.
    impact: medium
  - recommendation: Monitor monthly usage via the Enterprise API dashboard to anticipate when free tier limits will be reached.
    impact: low
