Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Use this endpoint when you need AI300 statistics and want to pay per-call with USDC via the x402 protocol without registering an account or obtaining an API key. Ideal for anonymous, wallet-gated access to nofx AI300 metrics in a crypto-native environment.

## Known failure modes

- Payment not received or insufficient USDC — 402 Payment Required response
- Invalid properties parameter — empty or malformed data array returned
- Service unavailable from vergex.trade backend — upstream error or timeout
- Wallet not configured for x402 payments — payment header missing, request blocked
- Empty data array returned when no stats match the query criteria

## How this service works

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