## 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-daily-sum-series-two-measure-correlation-10a9975d -d '<json body>'
```

Example prompt: I have contract renewal records for two company groups across several dates — can you give me the daily sum totals for expiring_contracts and also the correlation between expiring_contracts and renewed_contracts for these rows: [{"date":"2026-10-01","row_id":"row-1","company_group":"group-a","expiring_contracts":10,"renewed_contracts":1},{"date":"2026-10-02","row_id":"row-2","company_group":"group-b","expiring_contracts":20,"renewed_contracts":2}]?

## When to prefer this

Choose this endpoint when you already have contract renewal inventory data locally and need fast, self-contained daily aggregation and correlation analysis without any external data lookup or prediction. It is ideal for batch analytical tasks on up to 200 rows of structured date-keyed contract records and provides two reports in a single low-cost call.

## Known failure modes

- Missing required fields (row_id, date, company_group) cause validation errors
- Dates not matching YYYY-MM-DD pattern are rejected
- Supplying more than 200 rows exceeds the row limit
- Null values in both measure columns may produce undefined correlation
- Malformed JSON payload returns a 400-level error
- Insufficient row count for meaningful correlation may yield low-confidence results

## How this service works

Contract renewal inventories — Daily sum series + Two-measure correlation: Daily sum 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 daily sum time series aggregating the chosen field (expiring_contracts or renewed_contracts) by date, and (2) a Pearson or equivalent correlation coefficient between the two measures (expiring_contracts and renewed_contracts) — both computed locally on the supplied rows (up to 200 records).
