# Navigation Paths — Duplicate Key Report + Category Frequencies

> Navigation Paths — Duplicate Key Report + Category Frequencies is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Analyzes supplied navigation path records to produce a duplicate key report and category frequency breakdown for path_length and search_ms fields.

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-duplicate-key-report-category-frequencies-369900a5 -d '<json body>'
```

Example prompt: Check my navigation path records for duplicate row IDs and give me a category frequency breakdown by game_area — here are 4 rows: row-1 on 2026-10-01 in group-a with path_length 10 and search_ms 1, row-2 on 2026-10-02 in group-b with path_length 20 and search_ms 2, row-3 on 2026-10-03 in group-a with path_length 15 and search_ms 3, and row-4 on 2026-10-04 in group-b with path_length 30 and search_ms 4.

## When to prefer this

Choose this endpoint when you need to simultaneously check for duplicate row keys and compute category frequency distributions on navigation path records (up to 200 rows) in a single low-cost call. Ideal for game analytics pipelines that need quick data quality audits on path_length and search_ms data without any external API dependencies or live lookups.

## Known failure modes

- Empty rows array or missing required fields (row_id, game_area, date, path_length, search_ms) cause validation errors
- More than 200 rows submitted exceeds the maxItems limit
- Invalid date format (not YYYY-MM-DD) triggers pattern validation failure
- Numeric fields out of allowed range cause schema rejection
- Payment failure via x402 protocol returns 402 status

## How this service works

Navigation paths — Duplicate key report + Category frequencies: Duplicate key report + Category frequencies 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

Returns two independent analytical reports: (1) a duplicate key report identifying any row_id collisions across the submitted records, and (2) a category frequency table showing how often each game_area value appears in the dataset. Both reports are computed locally on the supplied data with no external lookups.
