# Supplier Delivery Evidence — String Normalisation + Secondary-Measure Weighted Mean

> Supplier Delivery Evidence — String Normalisation + 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 2026-10-25).

Normalises string fields and computes a secondary-measure weighted mean over supplier delivery evidence records (deliveries, on_time_deliveries) for up to 200 rows, returning two analytical reports.

## 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-string-normalisation-secondary-measure-8bf5cf18 -d '<json body>'
```

Example prompt: I have 150 rows of supplier delivery evidence with company_group, date, deliveries, and on_time_deliveries fields — can you run string normalisation and compute the secondary-measure weighted mean on the on_time_deliveries column?

## When to prefer this

Choose this endpoint when you have tabular supplier delivery evidence (up to 200 rows) and need both string field normalisation and a secondary-measure weighted mean computation in a single call without requiring live lookups, predictions, or external integrations. It is well-suited for batch reporting on supplier on-time delivery performance where data is already available locally.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected or truncated
- Missing required fields (row_id, company_group, date, deliveries, on_time_deliveries) cause validation errors
- Invalid date format (not YYYY-MM-DD) triggers schema validation failure
- Null values in numeric fields may affect weighted mean computation
- Invalid field enum value (not 'deliveries' or 'on_time_deliveries') causes error
- Payment failure (insufficient USDC balance) blocks endpoint access

## How this service works

Supplier delivery evidence — String normalisation + Secondary-measure weighted mean: String normalisation + 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

Two analytical reports per call: (1) a string-normalised version of the input delivery evidence records, and (2) a secondary-measure weighted mean computed over the selected numeric field (deliveries or on_time_deliveries), grouped by company_group and/or date, covering up to 200 input rows.
