# Label Review — Numeric Row Ordering + Trailing Mean Series

> Label Review — Numeric Row Ordering + Trailing Mean Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Computes numeric row ordering and trailing mean series for label review records (reviewed_records and changed_labels) across up to 200 rows.

## 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 label-review-numeric-row-ordering-trailing-mean-series-721ccb5f -d '<json body>'
```

Example prompt: I have 4 label review records from October 2026 — can you run numeric row ordering and a trailing mean (window size 2) on the reviewed_records field? The rows are: row-1 group-a 2026-10-01 reviewed=10 changed=1, row-2 group-b 2026-10-02 reviewed=20 changed=2, row-3 group-a 2026-10-03 reviewed=15 changed=3, row-4 group-b 2026-10-04 reviewed=30 changed=4.

## When to prefer this

Choose this endpoint when you need both numeric row ordering and a trailing mean series computed together on label review data (reviewed_records and changed_labels) in a single low-cost call. It is ideal for ML ops pipelines tracking annotation throughput and label change rates over time, especially when you want smoothed trend analysis without any external data enrichment or prediction.

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — schema validation error
- Invalid date format (not YYYY-MM-DD) — pattern validation failure
- Window size less than 2 or greater than 200 — schema rejection
- Field value not one of 'reviewed_records' or 'changed_labels' — enum validation error
- Null numeric values in required fields may affect mean computation
- Payment not completed — x402 payment required before response

## How this service works

Label review — Numeric row ordering + Trailing mean series: Numeric row ordering + Trailing mean series for supplied label review records (reviewed_records, changed_labels). 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 analytical reports for the supplied label review rows: (1) a numeric row ordering that ranks each row by the selected metric, and (2) a trailing mean series that smooths the chosen field (reviewed_records or changed_labels) over the specified window size. Results are computed locally with no external lookups.
