# Label Review — Numeric Interval Filter + Explicit Missing-Value Fill

> Label Review — Numeric Interval Filter + Explicit Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Filters label review records to a numeric interval and fills missing values using zero, mean, or median imputation, returning two analytical reports for up to 200 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 label-review-numeric-interval-filter-explicit-missing-value-fill-94ce1453 -d '<json body>'
```

Example prompt: Can you filter my label review records to only keep rows where reviewed_records is between 0 and 500, fill any missing reviewed_records values using the median method, and give me the two analytical reports? Here are up to 200 rows with row_id, dataset_group, date, reviewed_records, and changed_labels.

## When to prefer this

Choose this endpoint when you have label review tabular data (reviewed_records, changed_labels) and need both numeric range filtering and missing-value imputation in a single call producing two reports. It is ideal for data cleaning pipelines prior to ML training, annotation audits, or QA workflows where outlier exclusion and null handling are both required. Prefer this over single-operation endpoints when you want both reports bundled for $0.01 without making two separate API calls.

## Known failure modes

- Fewer than 1 or more than 200 rows supplied — rejected with validation error
- minimum value exceeds maximum value — logically invalid interval
- Invalid date format (not YYYY-MM-DD) in any row — schema validation failure
- row_id missing or empty — required field error
- Field enum value not in [reviewed_records, changed_labels] — schema rejection
- Method enum not in [zero, mean, median] — schema rejection
- All values in selected field are null — mean/median fill may be undefined

## How this service works

Label review — Numeric interval filter + Explicit missing-value fill: Numeric interval filter + Explicit missing-value fill for supplied label review records (reviewed_records, changed_labels). 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

Two independent analytical reports derived from the supplied label review rows: one covering the numeric interval-filtered view of the selected field (reviewed_records or changed_labels), and one covering the explicit missing-value fill result. Both reports are computed locally without external lookups or predictions, covering up to 200 input rows.
