## 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-qualification-duplicate-key-report-equal-width-histogram-3e85f678 -d '<json body>'
```

Example prompt: Can you run a duplicate key report and an equal-width histogram with 10 bins on the checked_criteria field for these 50 supplier qualification records I'm uploading?

## When to prefer this

Choose this endpoint when you need quick, local statistical summaries — specifically a duplicate key report and equal-width histogram — on a small-to-medium supplier qualification dataset (up to 200 rows) without requiring live data lookup, external enrichment, or predictive modeling. It is ideal for data quality audits and distribution analysis at low cost ($0.01 USDC for both reports together).

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row validation failure
- Numeric field values outside ±1,000,000,000,000 range rejected
- Empty rows array returns an error
- Invalid field enum value (not checked_criteria or met_criteria) causes rejection
- bins value outside 1–30 range causes validation error

## How this service works

Supplier qualification — Duplicate key report + Equal-width histogram: Duplicate key report + Equal-width histogram for supplied supplier qualification records (checked_criteria, met_criteria). 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 independent analytical reports: (1) a duplicate key report identifying any rows sharing the same key values, and (2) an equal-width histogram showing bin boundaries and row counts for the selected numeric field (checked_criteria or met_criteria), covering up to 200 input rows.
