# Company Filing Inventories — Category Frequencies + Equal-Width Histogram

> Company Filing Inventories — Category Frequencies + Equal-Width Histogram 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 category frequency counts and an equal-width histogram for available_filings or expected_filings across supplied company filing inventory records (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 company-filing-inventories-category-frequencies-equal-width-histogram-89586be8 -d '<json body>'
```

Example prompt: Analyze my company filing inventory data — I have 150 rows with available_filings and expected_filings values for groups like 'group-a' and 'group-b' — give me the category frequencies and a 10-bin equal-width histogram for available_filings.

## When to prefer this

Choose this endpoint when you need both a categorical frequency breakdown and a numeric histogram for company filing inventory data in a single call. Ideal when you have up to 200 rows of structured filing records and want local statistical analysis without any external lookups or predictions. Prefer this over separate analytics tools when cost efficiency matters — two reports for $0.01 USDC — and when your data fits the available_filings/expected_filings schema.

## Known failure modes

- Rows array empty or missing — validation error returned
- Row count exceeds 200 — request rejected
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Bins value outside 1–30 range — rejected
- Invalid field enum value (not available_filings or expected_filings) — error
- Null values in numeric fields may affect histogram computation
- Missing required row fields (row_id, company_group, date) — validation error
- Payment not included or insufficient — x402 payment required response

## How this service works

Company filing inventories — Category frequencies + Equal-width histogram: Category frequencies + Equal-width histogram 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 analytical reports: (1) category frequency counts showing how many records fall into each company_group category, and (2) an equal-width histogram for the selected numeric field (available_filings or expected_filings) with configurable bin count — including bin boundaries and counts per bin. Both reports are computed locally from the supplied rows with no external data lookups.
