# Supplier Delivery Evidence — String Normalisation + Two-Measure Correlation

> Supplier Delivery Evidence — String Normalisation + Two-Measure Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Normalises supplier delivery evidence strings and computes two-measure correlation analysis (deliveries vs on_time_deliveries) across up to 200 rows, returning two analytical reports.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-two-measure-correlation-1474798c -d '<json body>'
```

Example prompt: Can you run a string normalisation and two-measure correlation analysis on our supplier delivery evidence? I have up to 50 rows with fields for row_id, company_group, date, deliveries, and on_time_deliveries — I need both analytical reports back.

## When to prefer this

Choose this endpoint when you need both string normalisation and a two-measure statistical correlation on supplier delivery evidence (deliveries + on_time_deliveries) in a single low-cost call, without requiring external data lookups or live predictions. Best suited for datasets of up to 200 rows processed locally and analytically.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, company_group, date, deliveries, on_time_deliveries) — validation error
- Date field does not match YYYY-MM-DD pattern — schema validation failure
- Payment of 0.01 USDC not completed — 402 Payment Required response
- Null values in numeric fields may reduce correlation reliability

## How this service works

Supplier delivery evidence — String normalisation + Two-measure correlation: String normalisation + Two-measure correlation 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 two analytical reports: (1) normalised string output for the supplied delivery evidence fields, and (2) a two-measure correlation analysis between the deliveries and on_time_deliveries columns across up to 200 input rows, computed entirely locally without external lookups.
