# Form Inventories — Numeric Row Ordering + Trailing Mean Series

> Form Inventories — 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).

Analyzes form inventory records by producing a numeric row ordering report and a trailing mean series for field_count or labelled_fields, processing up to 200 rows offline.

## 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 form-inventories-numeric-row-ordering-trailing-mean-series-897f3761 -d '<json body>'
```

Example prompt: Can you rank my form inventory rows by field_count and also compute a 3-period trailing mean for field_count? Here are my records: row-1 on 2026-10-01 in group-a with field_count=10 and labelled_fields=1, row-2 on 2026-10-02 in group-b with field_count=20 and labelled_fields=2, row-3 on 2026-10-03 in group-a with field_count=15 and labelled_fields=3.

## When to prefer this

Choose this endpoint when you need both a numeric ranking of form inventory rows and a rolling/trailing mean series computed offline from your own supplied data, without requiring any external data lookup, prediction, or live data feed. It is ideal for batch statistical summarization of form metadata (field counts, labelled fields) across up to 200 records in a single low-cost call.

## Known failure modes

- Fewer than 1 row supplied — returns validation error
- More than 200 rows supplied — exceeds limit, rejected
- window parameter larger than number of rows — trailing mean may be undefined for early rows
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Null values in field_count or labelled_fields — may produce null/incomplete mean values
- Invalid field enum value — rejected by schema

## How this service works

Form inventories — Numeric row ordering + Trailing mean series: Numeric row ordering + Trailing mean series for supplied form inventories records (field_count, labelled_fields). 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: (1) a numeric row ordering of the supplied form inventory records ranked by the chosen field, and (2) a trailing mean series computed over the specified window for that field — all processed locally against the provided data, with no external lookups.
