# Contract Renewal Inventories — Category Frequencies + Adjacent Row Changes

> Contract Renewal Inventories — Category Frequencies + Adjacent Row Changes 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 rows of contract renewal inventory data (expiring_contracts, renewed_contracts) to produce category frequency distributions and adjacent row change 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 contract-renewal-inventories-category-frequencies-adjacent-row-changes-933f800b -d '<json body>'
```

Example prompt: I have a list of contract renewal records with dates, company groups, expiring_contracts, and renewed_contracts values — can you run category frequency and adjacent row change analysis on this data for the expiring_contracts field?

## When to prefer this

Choose this endpoint when you have tabular contract renewal inventory data (up to 200 rows) and need two fast, local analytical reports — category frequency distributions and sequential row-change analysis — without any live lookups, predictions, or external integrations. Ideal for lightweight, deterministic batch analytics on supplied data at low cost ($0.01 USDC for both reports).

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, company_group) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Field value outside allowed numeric range — schema rejection
- Empty rows array — minimum 1 item required
- Null values in numeric fields may affect change calculations

## How this service works

Contract renewal inventories — Category frequencies + Adjacent row changes: Category frequencies + Adjacent row changes 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 for the supplied rows: (1) category frequencies showing how often each company_group (or category) appears across the dataset, and (2) adjacent row changes showing the difference between consecutive row values for the selected field (expiring_contracts or renewed_contracts). Covers up to 200 rows per call.
