## When to prefer this

Use this endpoint when you need to retrieve members of a specific named X/Twitter list without managing X API keys or OAuth credentials, and you want to pay per call using USDC micropayments via x402 on Base or Solana. Prefer this over direct X API access when you want frictionless, keyless access to list data for lightweight or infrequent lookups.

## Known failure modes

- List slug not found for given username — returns error code in JSON
- Username does not exist on X/Twitter — returns error in data field
- List is private and inaccessible — access denied response
- Invalid slug or name format — malformed request error
- Payment not completed — 402 Payment Required before data is returned
- Rate limiting or upstream X API throttling — temporary failure
