## When to prefer this

Use this endpoint when you need to identify which users retweeted a specific tweet by ID, especially for audience analysis, influencer tracking, or monitoring tweet amplification. Prefer over general Twitter search when you already have the tweet ID and need the retweet graph.

## Known failure modes

- Invalid or non-existent tweet ID returns an error or empty result
- Tweet may have been deleted, returning not-found error
- Rate limiting or payment failure may block the request
- Pagination cursor mismatch may cause duplicate or skipped results
- Private or protected tweets may return no retweeters
