# Navigation Paths — Numeric Row Ordering + Explicit Missing-Value Fill

> Navigation Paths — Numeric Row Ordering + 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 2026-11-02).

Sorts navigation path records by numeric fields and fills missing values using zero, mean, or median imputation, returning two analytical reports for up to 200 rows.

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 navigation-paths-numeric-row-ordering-explicit-missing-value-fill-3c882977 -d '<json body>'
```

Example prompt: I have 4 navigation path records for different game areas — can you sort them by path_length and fill any missing path_length values using the median? The rows are: row-1 group-a 2026-10-01 path_length=10 search_ms=1, row-2 group-b 2026-10-02 path_length=null search_ms=2, row-3 group-a 2026-10-03 path_length=15 search_ms=3, row-4 group-b 2026-10-04 path_length=30 search_ms=4.

## When to prefer this

Choose this endpoint when you have a bounded dataset of navigation path records (up to 200 rows) with path_length or search_ms fields that need both numeric sorting and missing-value imputation in a single call. Ideal for game analytics pipelines where data cleaning and ordering are needed together without external API dependencies. If you need more than 200 rows, a different batch processing solution is required.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (must be YYYY-MM-DD) causes row validation failure
- Unknown fill method enum value causes parameter error
- All values in target field are null — mean/median imputation may be undefined
- row_id missing or empty string triggers required-field validation error
- Numeric values outside ±1,000,000,000,000 range rejected

## How this service works

Navigation paths — Numeric row ordering + Explicit missing-value fill: Numeric row ordering + 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 analytical reports covering: (1) the navigation path rows reordered by the specified numeric field (path_length or search_ms), and (2) the same dataset with missing values in that field replaced using the chosen fill method (zero, mean, or median). Up to 200 input rows are processed using local analytical engines with no external lookups.
