## 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 discounted-present-value-single-calculation-d1807c43 -d '<json body>'
```

Example prompt: What is the discounted present value of $12,000 received in 2 years, assuming an annual effective interest rate of 5%?

## When to prefer this

Choose this endpoint when you need a single, bounded discounted present value computation for one future cash flow with a known annual effective rate and time horizon. It is ideal for quick one-off financial math checks where a formula explanation and units are required alongside the result. Prefer this over multi-record batch calculators when only one data point needs to be evaluated.

## Known failure modes

- Missing required fields (future_value, annual_effective_rate_percent, years) returns an error
- years value outside 0–100 range rejected
- annual_effective_rate_percent outside -99 to 100 range rejected
- future_value exceeding ±1 trillion rejected
- Payment of 0.01 USDC not completed results in 402 Payment Required
