## 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 commercial-proposal-comparisons-daily-sum-series-two-measure-661cc2fe -d '<json body>'
```

Example prompt: I have a list of up to 200 commercial proposal records with row IDs, company groups, dates, quoted amounts, and delivery days — can you run both a daily sum series and a two-measure correlation on the quoted_amount field across all of them?

## When to prefer this

Choose this endpoint when you need both a day-by-day aggregated sum series AND a correlation between quoted_amount and delivery_days from a batch of commercial proposal or bid records (up to 200 rows), all in one $0.01 call. It is ideal for procurement analytics, vendor comparison, and RFQ analysis where you want to understand price trends over time and the statistical relationship between cost and lead time without any external lookups or predictions.

## Known failure modes

- More than 200 rows submitted — request exceeds row limit
- Missing required fields (row_id, date, company_group) on any row — validation error
- Invalid date format (not YYYY-MM-DD) — pattern mismatch error
- All numeric values null — insufficient data for correlation computation
- Payment not included or insufficient — x402 payment required error

## How this service works

Commercial proposal comparisons — Daily sum series + Two-measure correlation: Daily sum series + Two-measure correlation for supplied commercial proposal comparisons records (quoted_amount, delivery_days). 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 analytical reports: (1) a daily sum time series showing aggregated values of the selected measure (quoted_amount or delivery_days) grouped by date, and (2) a two-measure correlation report showing the statistical relationship between quoted_amount and delivery_days across the supplied rows. Both reports are computed locally from the provided data (up to 200 rows) with no external data lookups.
