Technical details
Endpoint
GEThttps://xspy.pro/api/v1/pro/twitter/:username/is-smart-follower?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly verify whether a specific Twitter/X account qualifies as a 'smart follower' of a particular KOL — useful for filtering audiences, validating influencer relationships, or screening accounts in crypto/Web3 contexts. Prefer this single-account check (5 credits) over the full top smart followers list (10 credits) when you only need to verify one account.
Side effects
- Invalid or non-existent Twitter username returns an error or null result
- KOL account not found or not tracked by xspy returns an error
- Rate limiting or insufficient credits returns a 402 or error response
- Network timeout if the crawl takes too long
- Username provided with @ symbol may cause parsing issues
