# Sampling Observations Analytics: Record Quality Audit + Exact Row Deduplication + Base-100 Series

> Sampling Observations Analytics: Record Quality Audit + Exact Row Deduplication + Base-100 Series 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 a base-100 index series 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-845dc086 -d '<json body>'
```

Example prompt: Can you run a record quality audit, exact deduplication check, and base-100 index series on my sampling observations dataset — here are 10 rows with row_id, dataset_group, date, sample_value, and sample_weight fields — index the sample_value column starting from row 0?

## When to prefer this

Choose this endpoint when you need three bundled local analytics — quality audit, deduplication, and base-100 indexing — on sampling observation data with sample_value and sample_weight fields, all in a single low-cost call. Prefer it over separate tools when your dataset is under 200 rows and you want consolidated reporting without external lookups or live data connections.

## Known failure modes

- Submitting more than 200 rows returns a validation error
- Missing required fields (row_id, date, sample_value, sample_weight, dataset_group) cause row-level errors
- Invalid date format (not YYYY-MM-DD) triggers a pattern validation failure
- base_index value out of range (0-199) or exceeding the number of submitted rows causes an index error
- Null values in sample_value or sample_weight may appear in quality audit flagging but won't block execution
- Payment of 0.01 USDC not included causes an x402 payment-required response

## How this service works

Sampling observations — Record quality audit + Exact row deduplication + Base-100 series: Record quality audit + Exact row deduplication + Base-100 series 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

Returns three independent analytical reports: (1) a record quality audit flagging missing values, type mismatches, and field-level issues; (2) an exact row deduplication report identifying fully duplicated records; and (3) a base-100 index series for the chosen numeric field (sample_value or sample_weight), normalized relative to the selected base row.
