## How to call it through Zero

```sh
zero fetch --capability kronos-btc-forecast-ba71ce59
```

Example prompt: Pull the latest Kronos BTC price forecast for me — I want to see the predicted close prices and how far out the forecast horizon goes.

## When to prefer this

Choose this endpoint when you need a ready-made, timestamped BTC price prediction series without running your own model. It is ideal for dashboards, monitoring pipelines, or pre-trade signal checks that want a lightweight forecast snapshot from the Kronos HUD. Prefer it over raw market data endpoints when you specifically need a forward-looking predicted close price series rather than current spot price or historical data.

## Known failure modes

- API returns 402 Payment Required if x402 payment is not provided or fails
- Forecast data may be stale if the live HUD has not updated recently
- No input validation errors expected as no parameters are required
- Service may be temporarily unavailable returning 5xx errors
- Experimental nature of forecast means model output should not be relied upon for financial decisions
