# Contract Renewal Inventories — Duplicate Key Report + Trailing Mean Series

> Contract Renewal Inventories — Duplicate Key Report + Trailing Mean Series 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).

Runs two local analytical reports on supplied contract renewal data: a duplicate key detection report and a trailing mean time series for either expiring 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-duplicate-key-report-trailing-mean-series-5216d8ae -d '<json body>'
```

Example prompt: Can you run a duplicate key check and a trailing mean series on my contract renewal data — I have rows with company_group, date, expiring_contracts, and renewed_contracts — use a rolling window of 3 and compute the trailing mean on the expiring_contracts field?

## When to prefer this

Choose this endpoint when you need quick, offline analytical reports on small-to-medium contract renewal datasets (up to 200 rows) without any external data lookup or prediction. It is ideal for data quality checks (duplicate detection) combined with time-series smoothing (trailing mean) in a single low-cost call. Prefer it over heavier analytics platforms when you just need lightweight, reproducible local computation on structured tabular renewal data.

## Known failure modes

- Fewer than 1 row supplied — request rejected by schema validation
- Window size exceeds number of rows — trailing mean may return nulls or partial values
- Malformed date strings not matching YYYY-MM-DD pattern — schema validation error
- Numeric values outside allowed range (±1 trillion) — schema rejection
- More than 200 rows submitted — request exceeds maximum row limit

## How this service works

Contract renewal inventories — Duplicate key report + Trailing mean series: Duplicate key report + Trailing mean series 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

Two independent reports: (1) a duplicate key report listing any rows sharing the same key fields (e.g. row_id or company_group+date), and (2) a trailing mean time series computed over the chosen field (expiring_contracts or renewed_contracts) using the specified window size — both covering up to 200 input rows.
