## 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-distribution-summary-777cb91e -d '<json body>'
```

Example prompt: I have 6 investment scenarios and want a distribution summary of their discounted present values — here are the inputs: future values of 10000, 12000, 15000, 8000, 11000, 13500; discount rates of 4%, 5%, 6%, 4.5%, 5.5%, 6.5%; and time horizons of 1, 2, 3, 1.5, 2.5, 3.5 years. Can you give me the quantiles and standard deviation across all of them?

## When to prefer this

Choose this endpoint when you need to statistically summarise a batch of 2–200 discounted present value calculations in a single call — particularly for sensitivity analysis, scenario comparison, or distribution reporting across varying discount rates and time horizons. Prefer this over a single-observation DPV calculator when you need quantiles or spread metrics across multiple inputs. Not suitable for real-time pricing, live market data feeds, or financial advice.

## Known failure modes

- Fewer than 2 rows provided — minimum of 2 observations required
- More than 200 rows provided — exceeds maxItems limit
- annual_effective_rate_percent outside range -99 to 100 — validation error
- years outside range 0 to 100 — validation error
- future_value outside range -1e12 to 1e12 — validation error
- Missing required fields (future_value, annual_effective_rate_percent, years) in any row — schema validation failure
- Non-numeric values passed for numeric fields — type error

## How this service works

Discounted present value - Distribution summary: Summarise up to 200 calculated observations with quantiles and population standard deviation. Metric: Discounted present value. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded distribution summary report.

## Output

A JSON object containing a distribution summary of up to 200 discounted present value calculations, including quantile breakpoints (e.g. min, Q1, median, Q3, max), population standard deviation, the formula used, currency/unit notes, and stated limitations of the calculation method.
