## 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 supplier-delivery-evidence-grouped-numeric-summary-equal-width-bd8233c4 -d '<json body>'
```

Example prompt: Can you run a grouped numeric summary and equal-width histogram on this supplier delivery dataset — I have 4 rows with company groups A and B, deliveries ranging from 10 to 30, and on-time deliveries from 1 to 4, dated October 2026? Use 5 bins and analyze the deliveries field.

## When to prefer this

Choose this endpoint when you have tabular supplier delivery evidence records and need both a grouped statistical summary and a histogram distribution report in a single call for up to 200 rows. It is best suited for supply chain analysts, logistics teams, or agents auditing vendor performance who need local, offline-style analytics without any external data lookup or prediction. Prefer it over general analytics APIs when you want a fixed-cost ($0.01 USDC), deterministic computation on your own supplied data.

## Known failure modes

- More than 200 rows submitted — request rejected at max 200 row limit
- Missing required row fields (row_id, company_group, date, deliveries, on_time_deliveries) — validation error
- Invalid date format (must match YYYY-MM-DD pattern) — schema validation failure
- bins value outside 1–30 range — rejected by schema
- Invalid field enum value (must be 'deliveries' or 'on_time_deliveries') — schema error
- Empty rows array — rejected by minItems:1 constraint
- Payment not provided or insufficient — x402 payment required

## How this service works

Supplier delivery evidence — Grouped numeric summary + Equal-width histogram: Grouped numeric summary + Equal-width histogram for supplied supplier delivery evidence records (deliveries, on_time_deliveries). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Two analytical reports: (1) a grouped numeric summary breaking down delivery metrics (count, mean, min, max, etc.) by company_group, and (2) an equal-width histogram showing the frequency distribution of the selected field (deliveries or on_time_deliveries) across the specified number of bins. Both reports are computed locally from the supplied rows with no external lookups.
