Twitter/X User Timeline Fetcher

Use this endpoint when you need to retrieve tweets from a specific known Twitter user by their screen name, especially for timeline monitoring, user research, or content aggregation. Prefer this over the search endpoint when you already know the exact account and want their personal tweet history rather than topic-based results.

• Username not found or account suspended — returns error indicating user does not exist
• Rate limit exceeded — returns 429-like error after too many requests
• Invalid or expired next_token — pagination cursor rejected
• Private/protected account — tweets not accessible without follow approval
• Payment not fulfilled — x402 payment required before response is returned
