## How to call it through Zero

```sh
zero fetch --capability tz-select-4h-market-selection-ecaeab22
```

Example prompt: What is Trading Zones' best 4H crypto pick right now — give me the selected coin, whether it's a long or short, the entry, stop loss, take profit, and confidence score.

## When to prefer this

Choose this endpoint when you want a single curated, high-conviction trade recommendation from a predefined watchlist (BTC, ETH, XRP, ONDO) rather than individual per-asset signals. Prefer this over the individual asset endpoints (BTC, ETH, XRP, ONDO 4H) when you want Trading Zones' own selector to choose the best setup, rather than evaluating all four yourself. Ideal for agents that need one actionable trade idea with complete parameters at low cost ($0.03 USDC) and no API key setup.

## Known failure modes

- Payment not processed correctly via x402 on Base Mainnet — returns 402 Payment Required
- No current selection available (between cycles) — direction may return NEUTRAL with null tz_select
- Stale signal if queried after valid_until timestamp has passed
- Network timeout or upstream data feed outage returns 5xx error
- Malformed request returns 400 Bad Request
