## 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 handel-halowerk-financing-cost-calculator-5a00d175 -d '<json body>'
```

Example prompt: Calculate the total swap and financing costs for a position with a notional cash value of €500,000, a daily swap cash of -€85, and a daily financing rate of 0.00005, held for 45 days.

## When to prefer this

Use this endpoint when you need a pure arithmetic calculation of swap and financing costs for a leveraged or derivative position and you already have all the numbers (notional, rates, days) from your own systems. It does not fetch live rates, access broker APIs, or provide investment advice — ideal for backtesting, trade journaling, or pre-trade cost estimation pipelines.

## Known failure modes

- Missing or out-of-range fields (days > 36500, notional > 1e12) return a validation error
- Negative notional values are rejected
- Non-numeric inputs cause a schema validation failure
- If daily_financing_rate or daily_swap_cash are omitted, partial or zero results may be returned

## How this service works

Swap- und lineare Finanzierungskosten.  Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.

## Output

Returns the computed total swap cost (daily_swap_cash × days) and total linear financing cost (daily_financing_rate × notional_cash × days), plus a combined total, all in the caller's units — no currency conversion or market data applied.
