## When to prefer this

Use this endpoint when you need to programmatically retrieve a specific X/Twitter user's pinned tweet without obtaining official Twitter API credentials or going through their signup process. Ideal for agents that need quick, pay-per-use access to Twitter data via x402 micropayments on Base (USDC).

## Known failure modes

- Invalid or nonexistent username returns error code with empty data object
- User has no pinned tweet returns empty data field
- Payment failure or insufficient USDC balance blocks access with HTTP 402
- Rate limiting or upstream X/Twitter API issues cause service unavailability
- Malformed name parameter returns schema validation error
