# Material Libraries String Normalisation and Exact Row Deduplication

> Material Libraries String Normalisation and Exact Row Deduplication is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Normalises strings and identifies exact duplicate rows in supplied material library records (material_count, texture_mb) across up to 200 rows, returning 2 analytical reports.

## 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 material-libraries-string-normalisation-and-exact-row-deduplication-8419cdb9 -d '<json body>'
```

Example prompt: Can you clean up my material library records — normalise the strings and find any exact duplicate rows? I have 4 rows with fields like asset_group, date, material_count, and texture_mb.

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) local analytical pass over up to 200 material library records to both normalise string fields and detect exact duplicate rows in a single call. Prefer it over general-purpose data cleaning tools when your data specifically involves creative asset fields (material_count, texture_mb, asset_group) and you want two structured reports from a single API call without any external data lookups or predictions.

## Known failure modes

- More than 200 rows submitted — endpoint rejects payloads exceeding the maxItems limit
- Missing required fields (row_id, asset_group, date, material_count, texture_mb) cause row-level validation errors
- Malformed date strings not matching YYYY-MM-DD pattern are rejected
- Numeric fields outside the allowed range trigger schema validation errors
- Empty rows array (minItems: 1 violated) returns an error

## How this service works

Material libraries — String normalisation + Exact row deduplication: String normalisation + Exact row deduplication for supplied material libraries records (material_count, texture_mb). 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 2 analytical reports: one covering string normalisation results (standardised field values for asset_group and other string fields) and one covering exact row deduplication results (identified duplicate row_ids and deduplicated dataset), all computed locally against the supplied rows with no external lookups.
