## 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-grok-models-list-x402-payment-gateway-dbaa4b90
```

Example prompt: Show me the list of Grok AI models available through claw402 so I can pick one for my request — I'll pay the $0.002 USDC fee with my wallet, no API key needed.

## When to prefer this

Use this endpoint when you need to discover available Grok model IDs before making inference calls, particularly when operating without traditional API keys and prefer to pay per-call in USDC via an x402-compatible wallet. Prefer over direct xAI API when you want keyless, crypto-native access.

## Known failure modes

- Payment not received — 402 response requiring USDC payment before access
- Empty data array returned if no models are currently available
- Malformed properties parameter yields unexpected or empty results
- Upstream vergex.trade or xAI Grok outage causes gateway error
- Wallet balance insufficient to cover $0.002 USDC fee

## 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 available Grok model identifiers and metadata accessible through the claw402 x402 gateway.
