## 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 bond-present-value-calculator-e5b023bb -d '<json body>'
```

Example prompt: What's the present value of a $10,000 face value bond with a 5% coupon rate and a 7% market yield over 10 years?

## When to prefer this

Use this endpoint when you need a fast, deterministic present value calculation for a plain vanilla bond using user-supplied parameters. It does not fetch live market rates or recommend yields — all inputs must be provided explicitly. Ideal for portfolio valuation tools, financial education apps, or any agent workflow that needs programmatic bond pricing without a full-featured financial data subscription.

## Known failure modes

- Missing required fields (face_value, coupon_percent, yield_percent, years) returns an error
- years outside range 1–100 rejected
- face_value exceeding 1 trillion rejected
- yield_percent or coupon_percent above 1000 rejected
- Non-integer years value rejected
- Network or worker runtime errors may return HTTP 5xx

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object containing the calculated present value of the bond (floating-point number) and a disclaimer notice clarifying that the result is a mathematical calculation from the supplied inputs only, with no tax, investment, or lending advice implied.
