## When to prefer this

Use this endpoint when you need to retrieve X/Twitter list metadata by ID without setting up official Twitter API credentials. Ideal for agents that need occasional list lookups and can pay $0.05 per call in USDC on Base via x402 micropayments rather than managing API keys or OAuth flows.

## Known failure modes

- Invalid or non-existent list ID returns error code in response body
- Private or deleted lists may return empty data or access-denied error
- Payment failure via x402 results in 402 status and no data returned
