## When to prefer this

Use this endpoint when you need to resolve a Twitter/X screen name to structured profile metadata, especially in workflows where you already know the handle and need account details. It is ideal for single-user lookups; for bulk lookups use the batch endpoint. Suitable for enriching social data pipelines or verifying Twitter identity.

## Known failure modes

- Screen name not found — returns 404 or empty result if user does not exist or account is suspended
- Invalid or missing userName parameter — returns 400 bad request
- Payment not processed — returns 402 if x402 payment header is missing or insufficient
- Rate limit exceeded — returns 429 if too many requests are made in a short window
