## 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 vergex-signal-lab-crypto-market-signal-lookup-123d45d3
```

## When to prefer this

Use this endpoint when you need on-chain trading signals or market data for a specific crypto asset from Vergex, accessed without API keys via USDC micropayment. Prefer this over traditional API-key-gated signal providers when operating in a wallet-native or x402-compatible agentic environment.

## Known failure modes

- Empty data array returned (code 0, data: []) if no signals exist for the given parameters
- Invalid or unsupported chain/symbol combination returns empty or error response
- Payment failure via x402 protocol results in 402 response before data is returned
- Missing required query parameters may result in malformed or empty response
