## When to prefer this

Use this endpoint when you need a quick, single numeric metric for how many 'smart' (high-quality, influential) followers a Twitter/X KOL has, without needing the full list. It is the most cost-efficient option (3 credits) compared to fetching the top smart followers list (10 credits) or checking individual smart follower status (5 credits).

## Known failure modes

- Username not found or does not exist — likely a 404 or empty result
- Invalid username format — error if '@' symbol is included or username contains invalid characters
- Insufficient credits (costs 3 credits) — payment or credit error if balance is too low
- Rate limiting or API throttling for high-volume requests
- Private or suspended accounts may return no data or an error
