# Company Filing Inventories — Adjacent Row Changes + Secondary-Measure Weighted Mean

> Company Filing Inventories — Adjacent Row Changes + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Computes adjacent row-to-row changes and secondary-measure weighted mean statistics for up to 200 company filing inventory records (available_filings, expected_filings).

## 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-adjacent-row-changes-secondary-measure-51c6f954 -d '<json body>'
```

Example prompt: Can you analyze my company filing inventory data and give me both the adjacent row changes and the weighted mean for available_filings? I have about 50 rows across groups like group-a and group-b, with dates from 2026-10-01 onward.

## When to prefer this

Choose this endpoint when you have structured tabular company filing inventory data (rows with dates, company groups, and filing counts) and need both sequential delta analysis (adjacent row changes) and a weighted statistical summary in a single low-cost call. It is best suited for batch analytical workloads on pre-collected data rather than live lookups or real-time monitoring.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected
- Missing required fields (row_id, date, company_group, available_filings, expected_filings) cause validation errors
- Invalid date format (must be YYYY-MM-DD) triggers pattern validation failure
- Numeric values outside ±1,000,000,000,000 are rejected
- Invalid field enum value (must be 'available_filings' or 'expected_filings') causes error
- Payment of 0.01 USDC not provided or rejected — endpoint inaccessible

## How this service works

Company filing inventories — Adjacent row changes + Secondary-measure weighted mean: Adjacent row changes + Secondary-measure weighted mean 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 for the supplied rows: (1) adjacent row changes showing the delta between consecutive rows for the selected filing field, and (2) a secondary-measure weighted mean aggregating the filing values across the dataset. Up to 200 rows are supported per call.
