# Company Filing Inventories — String Normalisation + Trailing Mean Series

> Company Filing Inventories — String Normalisation + 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 2026-10-20).

Applies string normalisation and trailing mean series analysis to company filing inventory records (available_filings, expected_filings) for up to 200 rows, producing two analytical reports.

## 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 company-filing-inventories-string-normalisation-trailing-mean-series-626152af -d '<json body>'
```

Example prompt: Run string normalisation and a trailing mean series (window size 7) on this set of company filing inventory rows — use available_filings as the target field — and give me both reports: group-a has 10, 15, 12 filings on 2026-10-01 through 2026-10-03, and group-b has 20, 30, 25 on the same dates.

## When to prefer this

Choose this endpoint when you have up to 200 rows of company filing inventory data (available_filings or expected_filings) and need both string normalisation and a trailing mean series computed together in one call at minimal cost ($0.01 USDC for both reports). It is ideal for offline/batch analytical preprocessing of filing records without requiring live lookups, external data, or professional assessment.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maximum limit
- Invalid date format (non-YYYY-MM-DD) — validation error
- Numeric values outside ±1,000,000,000,000 — schema violation
- Missing required fields (row_id, company_group, date, available_filings, expected_filings) — schema error
- Window size larger than number of rows — trailing mean may return partial or empty series
- Payment not included or insufficient — x402 payment required error

## How this service works

Company filing inventories — String normalisation + Trailing mean series: String normalisation + Trailing mean series for supplied company filing inventories records (available_filings, expected_filings). 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 independent analytical reports computed locally: (1) string-normalised representation of the selected filing inventory field, and (2) a trailing mean (rolling average) series over that field using the specified window size — both applied across up to 200 supplied rows, grouped by company_group and date.
