## 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-nofx-long-short-list-5da664e4
```

Example prompt: Pull the latest long-short position list from the claw402 NoFX endpoint — grab up to 20 results and pay with my USDC wallet.

## When to prefer this

Use this endpoint when you need a simple list of current long/short positions or signals from the vergex.trade NoFX market data feed, you want to pay per-call without API key registration, and you are operating in an x402-compatible USDC payment environment. Prefer this over traditional API key-based market data services when building permissionless or wallet-native trading agents.

## Known failure modes

- Payment not received or insufficient USDC balance — 402 response with payment requirements
- Limit parameter not a valid string-encoded integer — 400 bad request
- Empty data array returned if no active positions exist — code 0, data: []
- Network or upstream vergex.trade outage — 5xx error
- Rate limiting or wallet throttling — 429 or payment rejection

## How this service works

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