## 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 delx-commerce-duplicate-record-audit-4e2ef658 -d '<json body>'
```

Example prompt: Can you audit this list of customer records for duplicates based on the 'id' field? I have 500 rows and want to know how many duplicate groups exist and how many records are duped.

## When to prefer this

Use this endpoint when you need a fast, pay-per-call duplicate audit on an in-memory or passed dataset without setting up a database or ETL pipeline. It is ideal for agents doing pre-import data quality checks, one-off deduplication audits, or validating data freshness. Prefer over general-purpose code execution when you want a deterministic, verifiable result with no signup overhead and a fixed $0.003 cost.

## Known failure modes

- Missing or empty 'records' array — returns error or empty result
- Missing or empty 'key_fields' array — unable to determine dedup key
- Malformed record objects that don't contain the specified key fields — may return zero duplicates incorrectly
- Payment failure via x402 protocol — request rejected before processing
- Very large record arrays may hit undocumented size limits

## How this service works
