## 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 crypto-trading-verdict-api-f5e905de -d '<json body>'
```

Example prompt: Get me the latest trading verdict for BTC-EUR — I want both the long position signal with confidence and risk summary, and the 15-minute daytrade setup with entry range, stop-loss, and take-profit.

## When to prefer this

Use this endpoint when an agent needs a structured, data-driven trading signal for a specific crypto pair, particularly when both positional (long-term) and short-term (15-minute daytrade) perspectives are needed in a single call. Prefer this over generic price feeds when you need actionable trade parameters like entry ranges, stop-losses, and take-profit targets with reward:risk context. The no-charge policy on stale verdicts makes it safe to poll without financial risk on empty results.

## Known failure modes

- 400 returned when no fresh/valid verdict exists for the requested layer — no charge applied
- Invalid or unsupported coin pair may result in error
- Upstream signal system outage may prevent verdict generation
- Malformed request body or missing required fields returns validation error

## How this service works

Live crypto trading verdict for a coin (e.g. BTC-EUR), resold from an upstream signal system. Two layers: 'long' (positional ALLOW_LONG/EXIT/HOLD with confidence, summary and primary risk) and 'daytrade' (a 15m LONG/EXIT setup with entry range, stop-loss, take-profit and reward:risk). Pick layer long|daytrade|both. No fresh verdict for the requested layer means 400 and no charge — you only pay for an actual, still-valid verdict. Factual model output, not investment advice.

## Output

Returns a structured verdict for the requested layer(s). The 'long' layer includes a positional signal (ALLOW_LONG, EXIT, or HOLD), a confidence value, a plain-language summary, and the primary risk factor. The 'daytrade' layer includes a 15-minute LONG or EXIT signal, an entry price range, stop-loss level, take-profit target, and the reward:risk ratio. If no fresh verdict is available for the requested layer, a 400 is returned and no charge is made.
