# Data Collection Completeness — Numeric Distribution + Secondary-Measure Weighted Mean

> Data Collection Completeness — Numeric Distribution + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-06).

Computes a numeric distribution and a secondary-measure weighted mean for data collection completeness records (observed vs. expected values), returning two analytical reports for up to 200 rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 data-collection-completeness-numeric-distribution-secondary-measure-aded3b00 -d '<json body>'
```

Example prompt: Can you run a numeric distribution and weighted mean analysis on my data collection completeness records? I have rows with course_group, date, observed_values, and expected_values — analyze the observed_values field across up to 200 rows and give me both reports.

## When to prefer this

Choose this endpoint when you need two simultaneous statistical reports — a numeric distribution plus a weighted mean — on data collection completeness records (observed vs. expected pairs) in an education or structured data context, with up to 200 rows per call and a fixed low cost of $0.01 USDC for both reports. Prefer it over general analytics APIs when you specifically need offline, no-external-lookup computation on completeness metrics grouped by course or category.

## Known failure modes

- Fewer than 1 row supplied — minimum of 1 row required
- More than 200 rows supplied — exceeds maximum row limit
- Invalid date format (must be YYYY-MM-DD)
- Missing required fields (row_id, observed_values, or expected_values) on any row
- Values outside the numeric range [-1,000,000,000,000 to 1,000,000,000,000]
- Invalid field selector — must be 'observed_values' or 'expected_values'
- Payment failure or insufficient USDC balance

## How this service works

Data collection completeness — Numeric distribution + Secondary-measure weighted mean: Numeric distribution + Secondary-measure weighted mean for supplied data collection completeness records (observed_values, expected_values). 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 numeric distribution of the selected field (observed_values or expected_values) across all supplied rows, and (2) a secondary-measure weighted mean where one field weights the other. Results are computed locally from the supplied data without any external lookup or prediction.
