## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability readx-x-twitter-list-timeline-9a375e56
```

Example prompt: Pull the latest tweet timeline from X list ID 1234567890 — I want to see all the recent posts from that curated list.

## When to prefer this

Use this endpoint when you need to read the tweet timeline of a specific X/Twitter list without managing Twitter API keys, especially when micropayment-per-call billing (USDC on Base or Solana) is preferred over subscription-based API access. Ideal for agents that need occasional or burst access to list timelines without committing to a recurring API plan.

## Known failure modes

- Invalid or non-existent list ID returns empty data or error code
- Private or restricted list returns access error
- Payment failure via x402 micropayment prevents API access
- Rate limiting or downstream X/Twitter API errors cause failures
- Malformed list ID format results in bad request error
