# Contract Renewal Inventories — Adjacent Row Changes + Explicit Missing-Value Fill

> Contract Renewal Inventories — Adjacent Row Changes + Explicit Missing-Value Fill 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 contract renewal inventory data by computing adjacent row changes and filling missing values using zero, mean, or median strategies across up to 200 rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-adjacent-row-changes-explicit-missing-414ec8cc -d '<json body>'
```

Example prompt: Can you run two analytical reports on my contract renewal inventory data — compute adjacent row changes and fill any missing values using the median — for these 50 rows of expiring_contracts and renewed_contracts grouped by company?

## When to prefer this

Choose this endpoint when you need two specific data-cleaning and analysis operations on contract renewal inventory data — adjacent row change computation and explicit null filling — without any external lookups or predictions. Ideal for preprocessing contract datasets before dashboarding or reporting, especially when working with up to 200 rows of timestamped, group-labeled renewal records.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, date, company_group) — validation error
- Invalid date format (must be YYYY-MM-DD) — pattern mismatch error
- Invalid method enum value (must be zero, mean, or median) — schema error
- Invalid field enum value (must be expiring_contracts or renewed_contracts) — schema error
- Payment of 0.01 USDC not included or rejected — 402 response

## How this service works

Contract renewal inventories — Adjacent row changes + Explicit missing-value fill: Adjacent row changes + Explicit missing-value fill 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) an adjacent row changes report showing the delta between consecutive rows for the specified field, and (2) an explicit missing-value fill report where nulls in the target field are replaced using the chosen strategy (zero, mean, or median). Both reports are computed locally from the supplied data with no external lookups.
