## 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 twit-sh-x-list-lookup-by-id-17a0acbc
```

Example prompt: Can you pull up the details for X list ID 84839422 — I want to know its name, description, owner, and how many members and subscribers it has?

## When to prefer this

Choose this endpoint when you have a specific Twitter/X List ID and need structured metadata about it — name, owner, member count, subscriber count — without setting up Twitter API credentials. It's ideal for AI agents that need to enrich list references, validate list quality, or gather context about curated communities in a fully autonomous, pay-per-request fashion via USDC on Base.

## Known failure modes

- Invalid or non-numeric list ID returns an error or empty response
- Private lists may return restricted or no data
- Deleted or suspended lists return not-found errors
- Payment failure via x402/USDC blocks the request
- Rate limiting or network timeouts on the provider side

## How this service works

Real-time Twitter/X data for AI agents. No sign-up, no API keys. Pay per request in USDC on Base via x402. Fully autonomous.

## Output

Returns a JSON object with the list's numeric ID, name, visibility mode (Public/Private), creation timestamp, description, member count, subscriber count, and the owner's profile (ID, name, username, verification status, bio, and public metrics like followers, following, tweets, and likes).
