ReadX Full Twitter/X Profile Lookup

Use this endpoint when you need a comprehensive, rich profile snapshot of an X/Twitter user in a single call — including bio, counts, banner, pinned tweet, and photo rail — rather than making multiple API calls. Prefer over basic profile endpoints when you need the full visual and social context of an account. Best for agents performing social research, influencer analysis, or building user context from a Twitter handle.

• Username not found — returns 404 or empty profile if the handle doesn't exist or the account is suspended
• Invalid handle format — returns validation error if handle contains special characters other than alphanumeric and underscore
• Private/protected account — may return limited or no profile data for locked accounts
• Rate limiting — too many requests may result in 429 errors
• Payment failure — x402 payment not processed, returns 402 Payment Required
