# Supplier Qualification Data Quality Suite — Record Audit, String Normalisation & Equal-Width Histogram

> Supplier Qualification Data Quality Suite — Record Audit, String Normalisation & Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Runs three local analytical reports on supplier qualification records: a record quality audit, string normalisation check, and equal-width histogram for checked_criteria or met_criteria fields.

## 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-data-quality-suite-record-audit-string-0eb78c58 -d '<json body>'
```

Example prompt: Can you run a record quality audit, string normalisation check, and a 10-bin equal-width histogram on my supplier qualification dataset? I have rows with row_id, company_group, date, checked_criteria, and met_criteria fields — here are 50 rows, and I want the histogram on the checked_criteria column.

## When to prefer this

Choose this endpoint when you have up to 200 supplier qualification rows and need three bundled local data quality reports (record audit, string normalisation, histogram) in a single low-cost call ($0.01 USDC). It is ideal for pre-import profiling, procurement data validation, or distribution analysis of qualification criteria — where no live external lookup, prediction, or professional assessment is needed and all analysis is self-contained on your submitted data.

## Known failure modes

- More than 200 rows submitted — request rejected
- Invalid date format (not YYYY-MM-DD) causes row-level validation failure
- bins parameter outside 1–30 range causes rejection
- field value not one of 'checked_criteria' or 'met_criteria' causes schema error
- All values null in selected field renders histogram meaningless
- Missing required row fields (row_id, date, etc.) cause record-level audit failures

## How this service works

Supplier qualification — Record quality audit + String normalisation + Equal-width histogram: Record quality audit + String normalisation + Equal-width histogram for supplied supplier qualification records (checked_criteria, met_criteria). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Returns three independent analytical reports for the supplied rows: (1) a record quality audit flagging completeness and validity issues per row, (2) a string normalisation report identifying inconsistencies in text fields such as company_group, and (3) an equal-width histogram of the selected numeric field (checked_criteria or met_criteria) divided into the specified number of bins (1–30, default 5). All analysis is performed locally on the submitted data with no external lookups.
