## 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-polygon-ticker-news-api-449319a7

## When to prefer this

Use this endpoint when you need financial or crypto news articles for a specific ticker symbol without requiring API key registration, paying only per call in USDC via x402 on Polygon network. Prefer over traditional data providers when operating in a wallet-native, keyless environment.

## Known failure modes

- Missing required ticker parameter returns empty data array
- Invalid date format for published_utc causes no results
- Limit or sort parameters with unexpected values may be ignored or cause errors
- Payment failure via x402 returns HTTP 402 before any data is returned
- Empty data array returned if no news exists for the given ticker and date range

## How this service works

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

## Output

A JSON response with a code field (0 for success) and a data array containing news articles associated with the queried ticker, potentially including headlines, sources, and publication timestamps.
