## 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-snapshot-all-x402-payment-gateway-f5cab483
```

Example prompt: Can you pull a full snapshot of all available Polygon market tickers from vergex.trade, including OTC instruments?

## When to prefer this

Use this endpoint when you need a comprehensive, no-registration market snapshot of all Polygon instruments at once and are willing to pay $0.005 USDC per call via x402 micropayment. Prefer it over API-key-based market data providers when your agent workflow favors wallet-based pay-per-call access without subscription overhead.

## Known failure modes

- Payment not received or invalid x402 USDC payment header — returns 402 Payment Required
- Malformed query parameters (e.g. invalid tickers string) — returns error code in response body
- No data available for requested tickers — returns empty data array with code 0
- Service unavailable from vergex.trade backend — returns 5xx or gateway error
- Rate limit or payment replay detected — payment rejected

## 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 status code (0 for success) and a data array containing all available Polygon market snapshot entries, which may include ticker symbols, instrument details, and pricing data.
