# Contract Renewal Inventories — Category Frequencies + Equal-Width Histogram

> Contract Renewal 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 2026-10-20).

Analyzes up to 200 contract renewal inventory records to produce category frequency counts and an equal-width histogram for either expiring_contracts or renewed_contracts.

## 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 contract-renewal-inventories-category-frequencies-equal-width-histogram-8180aa80 -d '<json body>'
```

Example prompt: Can you analyze these 150 contract renewal records and give me both a category frequency breakdown by company group and a 10-bin equal-width histogram for expiring_contracts?

## When to prefer this

Choose this endpoint when you have up to 200 contract renewal records with expiring and renewed contract counts and need both a categorical frequency breakdown and a numeric histogram in a single low-cost call. It is ideal for offline batch summarization of renewal inventory snapshots where no live data lookup, prediction, or external enrichment is needed. Prefer it over general-purpose analytics tools when cost ($0.01 USDC for both reports) and simplicity matter and the dataset fits within 200 rows.

## Known failure modes

- More than 200 rows submitted — request rejected, trim to max 200
- Invalid date format (not YYYY-MM-DD) causes row validation failure
- Missing required fields (row_id, company_group, date) result in schema rejection
- bins value outside 1–30 range causes parameter validation error
- Null values in the selected numeric field may produce incomplete histogram bins
- Empty rows array returns an error — at least 1 row required

## How this service works

Contract renewal inventories — Category frequencies + Equal-width histogram: Category frequencies + Equal-width histogram for supplied contract renewal inventories records (expiring_contracts, renewed_contracts). 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: (1) category frequencies showing how records are distributed across company_group values, and (2) an equal-width histogram with configurable bins (1–30) showing the value distribution of the selected numeric field (expiring_contracts or renewed_contracts). Both reports are computed locally against the supplied rows with no external lookups.
