## 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 halowerk-risk-reward-ratio-calculator-6c5cb2e0 -d '<json body>'
```

Example prompt: I'm going long on this trade — entry at 45.20, stop-loss at 44.50, and my target is 47.00. What's the risk-reward ratio?

## When to prefer this

Use this endpoint when you need a pure, stateless computation of risk-reward ratio from caller-supplied prices — it performs no market data lookup, no broker connection, and no trade execution. Prefer it for automated trade screening, pre-entry checklists, or any workflow that already has price levels and just needs the R:R math done reliably and cheaply.

## Known failure modes

- Entry, stop, or target prices missing or zero — validation error returned
- Stop equals entry price — would produce division by zero or invalid ratio
- Direction value not -1 or 1 — enum validation failure
- Prices outside allowed range (below 1e-12 or above 1e12) — rejected by schema
- Illogical combination, e.g. stop above entry for a long trade — may return negative or nonsensical ratio

## How this service works

Chance-Risiko-Verhältnis.  Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.

## Output

Returns the computed risk-reward ratio along with the absolute risk (distance from entry to stop) and reward (distance from entry to target), allowing the caller to assess whether the trade setup meets their minimum R:R threshold.
