# Contract Renewal Inventories — Base-100 Series + Two-Measure Correlation

> Contract Renewal Inventories — Base-100 Series + Two-Measure Correlation 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).

Computes a Base-100 index series and a two-measure correlation report for supplied contract renewal records (expiring_contracts, renewed_contracts) across 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 contract-renewal-inventories-base-100-series-two-measure-correlation-5f958836 -d '<json body>'
```

Example prompt: I have 4 rows of contract renewal data for group-a and group-b from October 2026 — expiring and renewed contract counts per day. Can you index them to a base-100 series starting at row 0 on the expiring_contracts field, and also run the two-measure correlation between expiring and renewed contracts?

## When to prefer this

Choose this endpoint when you have tabular contract renewal records with expiring and renewed counts and need both a normalized trend index (Base-100) and a statistical correlation between the two measures in a single paid call. It is ideal for offline batch analysis of up to 200 rows of supplied data where no live data fetch, external prediction, or professional assessment is needed. At $0.01 USDC for both reports, it is cost-effective for lightweight analytical pipelines.

## Known failure modes

- Missing required fields (row_id, date, expiring_contracts, renewed_contracts) cause validation errors
- More than 200 rows submitted — exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- base_index out of range (must be 0–199 and within actual row count)
- Null values in both measure columns may degrade correlation output
- Payment failure (insufficient USDC balance) blocks execution

## How this service works

Contract renewal inventories — Base-100 series + Two-measure correlation: Base-100 series + Two-measure correlation 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) a Base-100 index series normalizing the selected field (expiring_contracts or renewed_contracts) relative to the specified base row, and (2) a correlation analysis between the expiring_contracts and renewed_contracts measures across the supplied rows. Both reports are computed locally on the supplied data with no external lookups.
