## 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-vergex-flow-markets-api-c77da6f3
```

Example prompt: Show me the latest flow markets on Ethereum from Vergex — give me the top 10 results from the last 24-hour window.

## When to prefer this

Choose this endpoint when you need on-chain flow market data from the Vergex trading platform and want to pay per-call in USDC without registering for an API key. Ideal for agents that operate autonomously with a crypto wallet and need lightweight, pay-as-you-go market data access. Prefer this over traditional REST APIs requiring OAuth or static API keys when building permissionless DeFi-native workflows.

## Known failure modes

- Empty data array returned if no markets match the specified chain or window
- Invalid chain value may return an error or empty result
- Payment failure via x402 protocol if wallet balance is insufficient
- Malformed query parameters may be silently ignored or cause a non-zero code response
- Rate limiting or payment processing delays may cause slow or failed responses

## 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 (field 'code') and a 'data' array containing flow market entries. The data array may include market identifiers, chain info, and trading flow metrics, though specific field names are not documented in the schema example.
