# Returns Handling — String Normalisation & Exact Row Deduplication

> Returns Handling — String Normalisation & 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 2026-11-02).

Cleans and deduplicates up to 200 returns-handling records by normalising strings and removing exact duplicate rows, producing 2 independent analytical reports on returned_units and processing_minutes.

## 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 returns-handling-string-normalisation-exact-row-deduplication-288f3b4c -d '<json body>'
```

Example prompt: Can you clean up my returns data for October — I have about 150 rows with store_group, date, returned_units, and processing_minutes fields — normalise the strings and remove any exact duplicate rows, then give me 2 reports on the returned_units and processing_minutes?

## When to prefer this

Choose this endpoint when you need offline, local-engine string normalisation and exact-row deduplication specifically for retail returns handling records (returned_units, processing_minutes) with up to 200 rows and want two bundled analytical reports at a fixed low cost — without needing live lookups, predictions, or external integrations.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, date, store_group) — validation error
- Malformed date format (not YYYY-MM-DD) — schema rejection
- Empty rows array — minimum 1 item required
- Numeric values outside allowed range (-1e12 to 1e12) — schema rejection

## How this service works

Returns handling — String normalisation + Exact row deduplication: String normalisation + Exact row deduplication for supplied returns handling records (returned_units, processing_minutes). 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 covering the cleaned dataset: one on returned_units and one on processing_minutes. Rows have been string-normalised and exact duplicates removed, with results covering up to 200 input records.
