## 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-list-timeline-api-866eaab4
```

Example prompt: Pull the latest tweets from the X/Twitter list with ID 1234567890 using ReadX — I don't have an API key so use the pay-per-call option.

## When to prefer this

Choose this endpoint when you need to read tweets from a specific curated X/Twitter list without setting up Twitter API credentials. Ideal for AI agents needing occasional, on-demand access to list timelines using USDC micropayments on Base or Solana rather than managing OAuth tokens or monthly API subscriptions.

## Known failure modes

- Invalid or non-existent list ID returns an error code in the response body
- List is private or inaccessible, resulting in an authorization error
- Payment failure via x402 micropayment protocol causes a 402 Payment Required response
- Rate limiting or quota exceeded on the ReadX platform
- Malformed list ID format causes a bad request error

## 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 containing the tweet timeline for the specified list, including tweet content, metadata, and author details, returned as structured JSON with a code and data field.
