# Sampling Observations Numeric Interval Filter and Keyed Dataset Comparison

> Sampling Observations Numeric Interval Filter and Keyed Dataset Comparison 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 two local analytical reports on user-supplied sampling observation rows: a numeric interval filter and a keyed dataset comparison across up to 200 records.

## 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-numeric-interval-filter-and-keyed-dataset-16870e89 -d '<json body>'
```

Example prompt: I have two sets of sampling observations — both with row IDs, dates, dataset groups, sample values, and sample weights (up to 200 rows each) — can you run a numeric interval filter on the sample_value field plus a keyed comparison between the two datasets and give me both reports?

## When to prefer this

Choose this endpoint when you have structured sampling observation data (up to 200 rows) and need both a numeric interval filter and a keyed cross-dataset comparison in a single low-cost call. It is ideal for offline/batch analytical scenarios where no external lookup or prediction is needed — just deterministic computation on supplied data. At $0.01 USDC for two reports, it is cost-efficient for lightweight statistical comparison tasks that do not require a full analytics platform.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) cause validation errors
- Null values in sample_value or sample_weight may affect interval filter results
- Invalid date format (non-YYYY-MM-DD) will fail pattern validation
- Values outside ±1,000,000,000,000 range are rejected
- Empty rows array (minItems:1 not met) returns error

## How this service works

Sampling observations — Numeric interval filter + Keyed dataset comparison: Numeric interval filter + Keyed dataset comparison for supplied sampling observations records (sample_value, sample_weight). 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 numeric interval filter showing which rows fall within the specified value range for the chosen field (sample_value or sample_weight), and (2) a keyed dataset comparison report matching rows across the primary and secondary datasets by key, highlighting differences in sample values and weights. No external data is fetched; all computation runs locally on the supplied rows.
