# Navigation Paths IQR Outlier Flags + Explicit Missing-Value Fill

> Navigation Paths IQR Outlier Flags + 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 2026-10-26).

Analyzes navigation path records (path_length, search_ms) to flag IQR-based outliers and fill missing values using a chosen method (zero, mean, or median), returning two independent analytical reports.

## 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 navigation-paths-iqr-outlier-flags-explicit-missing-value-fill-9b5b4c60 -d '<json body>'
```

Example prompt: I have up to 200 rows of navigation path records with path_length and search_ms values — some may have nulls or outliers. Can you run IQR outlier flagging and fill missing values using median imputation on path_length, and give me both reports?

## When to prefer this

Choose this endpoint when you have navigation path records (path_length and/or search_ms) that need both IQR-based outlier flagging and missing-value imputation in a single call, especially for game area navigation datasets up to 200 rows. Ideal for lightweight, local analytical processing without any external lookups or live data dependencies. Prefer this over general-purpose data tools when you need two co-produced reports (outlier flags + fill audit) cheaply at $0.01 USDC per call.

## Known failure modes

- Fewer than 1 row supplied — minItems:1 violation returns validation error
- More than 200 rows supplied — maxItems:200 exceeded, request rejected
- Invalid date format (not YYYY-MM-DD) — pattern validation failure
- Field value outside numeric bounds — maximum/minimum range violation
- Invalid fill method — must be one of zero, mean, median
- Invalid field selection — must be path_length or search_ms
- Missing required row fields (row_id, game_area, date) — schema validation error
- Payment not included or insufficient — x402 payment required response

## How this service works

Navigation paths — IQR outlier flags + Explicit missing-value fill: IQR outlier flags + Explicit missing-value fill for supplied navigation paths records (path_length, search_ms). 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 for the supplied navigation path rows: (1) IQR-based outlier flags indicating which rows contain extreme values in the target field, and (2) an explicit missing-value fill report showing which cells were imputed and the fill values applied, based on the chosen method (zero, mean, or median). Up to 200 rows processed per call.
