## 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-lookup-by-slug-d20dff93
```

Example prompt: Can you pull up the details for the Twitter list called 'crypto-builders' owned by the user 'elonmusk' — I want to see the list's description, member count, and metadata?

## When to prefer this

Use this endpoint when you need to retrieve metadata about a specific X/Twitter list identified by a known username and list slug, without holding official X API keys. Ideal for agents that need to programmatically access Twitter list data using USDC micropayments on Base or Solana via the x402 protocol.

## Known failure modes

- List slug or username not found — returns error code or empty data
- Private or restricted list — returns access denied or empty response
- Micropayment (x402) not fulfilled — request rejected before reaching the API
- Invalid slug format — malformed URL parameters cause a 4xx error
- Rate limit or overload on the upstream X/Twitter data source — slow or failed response

## How this service works

ReadX is a read-only X/Twitter JSON API. Profiles, timelines, tweets, search, lists, followers & following — pay per call with x402 micropayments in USDC on Base or Solana. No API keys.

## Output

A JSON object with code 0 and a data field containing the X/Twitter list's metadata, such as name, description, owner, member count, and other list-level attributes.
