## 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 trabot-pair-arb-desk-831c9e49
```

Example prompt: Pull the current ETH/BTC pair arb desk signal from TraBot — I want to see the z-score and whether there's a stat arb opportunity open right now, along with the module stats.

## When to prefer this

Choose this endpoint when you need a real-time z-score-based statistical arbitrage signal specifically for the ETH/BTC pair, and you want module-level performance stats bundled in a single call. Prefer this over generic price feeds when your agent needs a pre-computed mean-reversion signal rather than raw OHLCV data. Best suited for agents running pair trading or stat arb strategies that need actionable signals with quantitative confidence metrics.

## Known failure modes

- Payment not settled — x402 payment required before data is returned
- Market data unavailable — upstream Kraken or exchange feed disruption may cause stale or missing z-score
- Rate limit exceeded — too many calls within the billing window
- Invalid query params — request rejected if unsupported method or param type provided
- Service downtime — trabotpro.it backend temporarily unreachable
