# Sampling Observations Analytics: Record Quality Audit + Exact Row Deduplication + Numeric Distribution

> Sampling Observations Analytics: Record Quality Audit + Exact Row Deduplication + Numeric Distribution is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Runs three local analytical reports on up to 200 sampling observation rows: a record quality audit, exact row deduplication, and numeric distribution analysis for sample_value or sample_weight.

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 sampling-observations-analytics-record-quality-audit-exact-row-ed12385e -d '<json body>'
```

Example prompt: Can you run a record quality audit, exact duplicate check, and numeric distribution report on my sampling observations dataset — here are up to 200 rows with row_id, dataset_group, date, sample_value, and sample_weight — and analyze the sample_value field for the distribution report?

## When to prefer this

Choose this endpoint when you need three complementary data quality and profiling reports in a single $0.01 call on a dataset of up to 200 sampling observation records. It is ideal for pre-analysis QA pipelines where you want quality auditing, deduplication, and distributional profiling in one batch without any external lookups or predictions. Prefer this over separate single-report endpoints when you need all three reports simultaneously to save cost and latency.

## Known failure modes

- Exceeding 200 rows causes a validation error — batch input must be split
- Rows missing required fields (row_id, date, sample_value, sample_weight) will fail schema validation
- Invalid date format (not YYYY-MM-DD) will be rejected
- Numeric values outside the allowed range (-1e12 to 1e12) will cause a validation error
- Empty rows array returns an error — at least 1 row is required

## How this service works

Sampling observations — Record quality audit + Exact row deduplication + Numeric distribution: Record quality audit + Exact row deduplication + Numeric distribution for supplied sampling observations records (sample_value, sample_weight). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Three independent analytical reports: (1) a record quality audit flagging issues such as missing values, malformed fields, and out-of-range data; (2) an exact row deduplication report identifying duplicate records; and (3) a numeric distribution summary (e.g. min, max, mean, percentiles, histogram bins) for the selected field (sample_value or sample_weight). All computed locally with no external lookups.
