# Form Inventories — String Normalisation + Duplicate Key Report

> Form Inventories — String Normalisation + Duplicate Key Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Normalises strings and generates a duplicate key report for up to 200 form inventory records containing field_count and labelled_fields data.

## 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-string-normalisation-duplicate-key-report-1bb74948 -d '<json body>'
```

Example prompt: I have a batch of form inventory records with site_group, date, field_count, and labelled_fields columns — can you run string normalisation and a duplicate key report on all of them? Here are 4 rows: row-1 for group-a on 2026-10-01 with field_count 10 and labelled_fields 1, row-2 for group-b on 2026-10-02 with field_count 20 and labelled_fields 2, row-3 for group-a on 2026-10-03 with field_count 15 and labelled_fields 3, row-4 for group-b on 2026-10-04 with field_count 30 and labelled_fields 4.

## When to prefer this

Use this endpoint when you need two bundled data-quality operations — string normalisation and duplicate key detection — applied together to form inventory records in a single low-cost call. It is ideal for batch pre-processing of up to 200 rows before loading into a dashboard or database, and is preferable over general-purpose data tools when you specifically have form field inventory data (field_count, labelled_fields, site_group) and want deterministic local analysis without any external API calls or predictions.

## Known failure modes

- Rows array exceeds 200 items — request rejected
- Missing required fields (row_id, site_group, date, field_count, labelled_fields) — validation error
- Malformed date strings not matching YYYY-MM-DD pattern — schema validation failure
- row_id empty or blank — minLength violation
- Payment not attached or insufficient USDC — 402 response

## How this service works

Form inventories — String normalisation + Duplicate key report: String normalisation + Duplicate key report for supplied form inventories records (field_count, labelled_fields). 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 independent analytical reports: (1) a string normalisation report showing standardised/cleaned string values for the supplied records, and (2) a duplicate key report identifying repeated or conflicting keys across up to 200 form inventory rows, all processed locally without external lookups.
