## 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 first-attempt-delivery-share-distribution-histogram-d04d5d47 -d '<json body>'
```

Example prompt: Take my 8 retail store records — each with attempted shipments and first-attempt deliveries — and generate a distribution histogram with 6 bins showing how first-attempt delivery share is spread across those stores.

## When to prefer this

Choose this endpoint when you need a statistical frequency distribution of first-attempt delivery share rates across a batch of retail shipment records, particularly when you want to understand spread, clustering, or outliers in delivery performance. Prefer this over raw summary statistics when the shape of the distribution matters (e.g. bimodal vs. normally distributed performance). Best for offline analysis of supplied data rather than live tracking or order management.

## Known failure modes

- Fewer than 2 rows supplied — minimum row count not met
- Bin count exceeds 30 or is less than 1 — validation error
- attempted_shipments value is zero or negative — exclusiveMinimum violation
- first_attempt_deliveries exceeds attempted_shipments — logically inconsistent data may produce skewed histogram
- More than 200 rows submitted — maxItems limit exceeded
- Non-numeric values in shipment fields — schema type error
