## How to call it through Zero

```sh
zero fetch --capability readx-list-members-api-db556ac5
```

Example prompt: Can you get me the members of Twitter list ID 1234567890 using ReadX — I want to see which accounts are in that list?

## When to prefer this

Use this endpoint when you need to retrieve members of a specific X/Twitter list by ID without managing X API keys, and you can pay $0.05 USDC per call via x402 micropayments on Base or Solana. Ideal for agents that need lightweight, pay-per-use access to Twitter list data without OAuth setup.

## Known failure modes

- Invalid or non-existent list ID returns an error code
- Private or restricted lists may return empty or access-denied response
- Payment failure via x402 micropayment results in 402 response before data is returned
- Malformed list ID parameter causes request to fail
- Rate limits or service downtime on the underlying X/Twitter data source may cause timeouts
