# Supplier Qualification Daily Sum Series and Two-Measure Correlation

> Supplier Qualification Daily Sum Series and 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 2026-10-23).

Computes a daily sum time series and a two-measure correlation report for supplier qualification data (checked_criteria and met_criteria) from up to 200 supplied 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 supplier-qualification-daily-sum-series-and-two-measure-correlation-bd28f024 -d '<json body>'
```

Example prompt: Can you run a daily sum series and a two-measure correlation on my supplier qualification records? I have up to 200 rows with dates, company groups, and values for checked_criteria and met_criteria — use checked_criteria as the primary field.

## When to prefer this

Choose this endpoint when you have pre-collected supplier qualification row data (up to 200 records) and need both a daily aggregated time series and a correlation between two numeric criteria measures in a single low-cost call. It is ideal for offline or batch analytical tasks on supplier compliance datasets where no live lookup, prediction, or external enrichment is needed. Prefer alternatives if you need more than 200 rows, real-time data ingestion, or more than two reports per call.

## Known failure modes

- Empty or missing rows array returns a validation error
- More than 200 rows submitted causes rejection due to maxItems constraint
- Invalid date format (not YYYY-MM-DD) fails schema validation
- row_id missing or blank causes required-field validation failure
- Numeric values outside ±1,000,000,000,000 are rejected
- Non-numeric values in checked_criteria or met_criteria (other than null) cause type errors
- Invalid field enum value (not checked_criteria or met_criteria) causes rejection

## How this service works

Supplier qualification — Daily sum series + Two-measure correlation: Daily sum series + Two-measure correlation for supplied supplier qualification records (checked_criteria, met_criteria). 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 selected measure (checked_criteria or met_criteria) by date, and (2) a two-measure correlation report quantifying the statistical relationship between checked_criteria and met_criteria across the supplied rows. Both reports are computed locally from the submitted data with no external lookups.
