## 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-article-entities-endpoint-1f7a0124
```

Example prompt: Can you pull all the named entities — people, organizations, and topics — mentioned in this Twitter article with ID 1234567890 using ReadX?

## When to prefer this

Use this endpoint when you need structured named-entity extraction from a specific Twitter/X article or tweet by its ID, without needing a traditional API key, and you are comfortable paying $0.05 USDC per call via x402 micropayments on Base or Solana. Prefer this over full Twitter API access when you only need entity data for individual posts and want a lightweight, pay-per-call model.

## Known failure modes

- Invalid or nonexistent article_id returns an error code in the response
- Payment failure via x402 micropayment results in 402 response and no data returned
- Malformed article_id format causes a bad request error
- Article may have been deleted or is unavailable, returning empty or error data
- Network timeout if X/Twitter upstream is slow
