# Supplier Delivery Evidence — Numeric Row Ordering + Secondary-Measure Weighted Mean

> Supplier Delivery Evidence — Numeric Row Ordering + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).

Computes numeric row ordering and secondary-measure weighted mean analytics on supplier delivery evidence records (deliveries, on_time_deliveries) for up to 200 rows, returning 2 reports per call.

## 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-numeric-row-ordering-secondary-measure-be724846 -d '<json body>'
```

Example prompt: Can you rank these supplier delivery records and compute a weighted mean of on_time_deliveries weighted by deliveries? I have 4 rows: row-1 for group-a on 2026-10-01 with 10 deliveries and 1 on-time, row-2 for group-b on 2026-10-02 with 20 deliveries and 2 on-time, row-3 for group-a on 2026-10-03 with 15 deliveries and 3 on-time, row-4 for group-b on 2026-10-04 with 30 deliveries and 4 on-time — use on_time_deliveries as the field.

## When to prefer this

Choose this endpoint when you have up to 200 supplier delivery records with deliveries and on_time_deliveries metrics and need both a numeric row ranking and a weighted mean statistic in a single low-cost ($0.01 USDC) call. It is ideal for offline/batch analytical reporting on pre-collected delivery evidence data where no live lookup, external data enrichment, or predictive modeling is needed.

## Known failure modes

- Fewer than 1 row supplied — minItems constraint violated
- More than 200 rows supplied — maxItems constraint exceeded
- Missing required fields (row_id, company_group, date, deliveries, on_time_deliveries) on any row
- Invalid date format (must match YYYY-MM-DD pattern)
- Null values in both deliveries and on_time_deliveries preventing weighted mean computation
- Invalid field enum value (must be 'deliveries' or 'on_time_deliveries')
- Payment failure via x402 protocol resulting in no response

## How this service works

Supplier delivery evidence — Numeric row ordering + Secondary-measure weighted mean: Numeric row ordering + Secondary-measure weighted mean 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

Returns 2 analytical reports per call: (1) a numeric row ordering of the supplied delivery evidence records ranked by the selected field, and (2) a secondary-measure weighted mean where one measure (e.g. on_time_deliveries) is weighted by the other (e.g. deliveries), computed locally without any external lookup or live data.
