## 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 audio-mastering-data-exact-row-deduplication-numeric-row-ordering-fccd7c42 -d '<json body>'
```

Example prompt: Can you deduplicate and numerically order my audio mastering records — I have up to 50 rows with integrated_lufs and true_peak_db values — and give me two reports on the integrated_lufs field?

## When to prefer this

Choose this endpoint when you need to clean and order a batch of audio mastering records (up to 200 rows) by removing exact duplicates and sorting numerically, and you want two structured reports back. It is ideal for post-session data hygiene on loudness metrics (LUFS, true peak dB) without needing real-time analysis, AI predictions, or external data enrichment.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, date, integrated_lufs, true_peak_db) causes rejection
- Invalid date format (not YYYY-MM-DD) triggers a schema validation error
- Empty rows array is rejected
- Invalid field enum value other than 'integrated_lufs' or 'true_peak_db' causes an error
- Payment failure or insufficient USDC balance prevents processing

## How this service works

Audio mastering — Exact row deduplication + Numeric row ordering: Exact row deduplication + Numeric row ordering for supplied audio mastering records (integrated_lufs, true_peak_db). 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 two analytical reports covering (1) exact row deduplication results identifying and removing duplicate records, and (2) numeric ordering of the supplied audio mastering rows. Reports are based entirely on the submitted data (up to 200 rows) with no external lookups. Fields analyzed include integrated_lufs and/or true_peak_db depending on the field selector.
