## 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 return-on-average-equity-distribution-summary-9ad91198 -d '<json body>'
```

Example prompt: Can you summarise the distribution of return on average equity for these 6 periods — net incomes of 3000, 3300, 2800, 3100, 2900, 3400 against average equities of 20000, 22000, 19000, 21000, 20500, 23000 — and give me the quantiles and standard deviation?

## When to prefer this

Choose this endpoint when you have a batch of 2–200 ROAE observations and need a statistical distribution summary (quantiles, population standard deviation) rather than a single point calculation. It is ideal for period-over-period analysis, cross-entity benchmarking, or investor reporting where spread and dispersion of return on equity matter. Not suitable for real-time data feeds, single-observation calculations, or financial advice.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 observations required
- average_equity value of zero or negative — exclusiveMinimum enforced, will return validation error
- More than 200 rows submitted — maxItems limit exceeded
- Non-numeric values in net_income or average_equity fields — schema validation failure
- Missing required fields net_income or average_equity in any row object
