Twitter Surf - User Tweets by Username

Use this endpoint when you need to programmatically fetch tweets from a specific public Twitter/X user by their username handle, especially in automated agent workflows that require paying per call via the x402 protocol. Prefer this over scraping when you need structured tweet data with optional reply filtering.

• User account not found or handle doesn't exist — returns error or empty result
• User account is private/suspended — access denied or empty response
• Rate limiting or upstream Twitter API restrictions — may return partial or no data
• Payment failure via x402 protocol — endpoint not accessible without valid payment
• Invalid or missing username in path — returns error
