# Form Inventories — Record Quality Audit + String Normalisation + Equal-Width Histogram

> Form Inventories — Record Quality 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 2026-10-23).

Runs three local analytical reports on up to 200 form inventory rows: a record quality audit, string normalisation, and an equal-width histogram over a chosen numeric field.

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 form-inventories-record-quality-audit-string-normalisation-equal-512c1c74 -d '<json body>'
```

Example prompt: Can you run a record quality audit, string normalisation, and a 10-bin equal-width histogram on my form inventory data — use field_count as the histogram field? I have about 50 rows with row_id, site_group, date, field_count, and labelled_fields.

## When to prefer this

Choose this endpoint when you need three bundled analytical operations — quality audit, string normalisation, and histogram — on form inventory data in a single low-cost call. It is best suited for offline or batch analysis of up to 200 rows where no live data lookup, prediction, or external action is needed. Prefer it over separate single-report endpoints when all three analyses are required simultaneously to save cost and round-trips.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Invalid date format (not YYYY-MM-DD) causes row rejection
- bins value outside 1–30 range triggers schema validation failure
- Missing required fields (row_id, field_count, labelled_fields) cause record-level quality failures
- Entirely null numeric columns may yield degenerate histogram output

## How this service works

Form inventories — Record quality audit + String normalisation + Equal-width histogram: Record quality audit + String normalisation + Equal-width histogram for supplied form inventories records (field_count, labelled_fields). 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: (1) a record quality audit flagging missing, null, or out-of-range values per row; (2) a string normalisation report standardising text fields like site_group; and (3) an equal-width histogram breaking the chosen numeric field (field_count or labelled_fields) into the requested number of bins with counts per bin. All computed locally with no external lookups.
