## 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 claw402-alpaca-news-via-x402-77af9224
```

Example prompt: Can you pull the latest 10 news articles for AAPL and TSLA from Alpaca, sorted by newest first, including the full article content?

## When to prefer this

Choose this endpoint when you need Alpaca Markets news data without registering for an Alpaca API key, especially in agentic or automated workflows that use USDC micropayments (x402 protocol). Ideal for lightweight, pay-as-you-go financial news lookups for specific stock symbols without account management overhead.

## Known failure modes

- Payment not received or insufficient USDC — request blocked with 402 response
- Invalid symbol format — returns empty data array
- Date range too broad or malformed start/end parameters — returns error or empty results
- Network timeout from upstream Alpaca API — returns error response
- Invalid sort or limit parameters — may return default results or error

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

Returns a JSON object with a code field (0 for success) and a data array containing news article objects from Alpaca Markets — typically including headline, summary, publication time, and related symbols.
