## 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 vextorium-staking-rewards-calculator-33440090 -d '<json body>'
```

Example prompt: How much will I earn staking 5000 tokens at 7.5% APY for 365 days with daily compounding, after a 5% validator commission, if the token price is $2.50?

## When to prefer this

Choose this endpoint when you need a detailed staking rewards breakdown including compounding effects, validator commission deduction, and USD conversion — particularly when you need per-day and per-month averages alongside totals. Prefer this over generic financial calculators when the context is specifically crypto staking with validator fees.

## Known failure modes

- Missing required fields (amount or apy_pct) returns a validation error
- Negative or zero values for amount or APY may return errors or nonsensical results
- Invalid body type (not json/form-data/text) returns a 400 error
- Very large numbers or edge-case APY values may produce unexpected output
- price_usd omitted means USD fields will be null or absent in response
