API Direct - Get Twitter/X User Followers

Choose this endpoint when you need a paginated, merged list of followers for a specific Twitter/X username and want to control the depth of retrieval (1–20 pages). It is ideal for audience analysis, influencer research, or competitive intelligence tasks where knowing who follows a given account is the primary goal. Prefer this over Twitter search endpoints when the target is follower identity rather than tweet content.

• Username not found — returns an error if the Twitter handle does not exist
• Private/protected account — may return no followers or an access error if the account is not public
• Rate limiting — too many requests in a short window may result in 429 errors
• Invalid username format — overly long or malformed usernames may be rejected
• Pages out of range — requesting fewer than 1 or more than 20 pages returns a validation error
• Payment failure — insufficient USDC balance or x402 payment not accepted results in 402 error
