# Physics Scenes — Duplicate Key Report + Adjacent Row Changes

> Physics Scenes — Duplicate Key Report + Adjacent Row Changes 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).

Analyzes up to 200 physics scene records to produce a duplicate key report and adjacent row change detection for body_count or step_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 physics-scenes-duplicate-key-report-adjacent-row-changes-8fe7dc73 -d '<json body>'
```

Example prompt: Can you run a duplicate key report and adjacent row changes analysis on my physics scene data — here are 4 rows with row_id, game_area, date, body_count, and step_ms — and check the body_count field for changes?

## When to prefer this

Choose this endpoint when you need fast, local analytical data-quality checks on physics scene records — specifically duplicate key detection and adjacent row change reporting — without needing live lookups, ML predictions, or external integrations. It's ideal for game developers auditing simulation datasets before loading or debugging frame-level inconsistencies in body_count or step_ms.

## Known failure modes

- Input rows array is empty or exceeds 200 items — validation error returned
- row_id field missing or exceeds 80 characters — schema validation failure
- field selector value not in enum ['body_count','step_ms'] — invalid input error
- date format not matching YYYY-MM-DD pattern — schema rejection
- Numeric values for body_count or step_ms outside allowed range — rejection

## How this service works

Physics scenes — Duplicate key report + Adjacent row changes: Duplicate key report + Adjacent row changes for supplied physics scenes records (body_count, step_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: (1) a duplicate key report listing any row_ids or key combinations that appear more than once in the supplied dataset, and (2) an adjacent row changes report showing value differences in the selected field (body_count or step_ms) between consecutive rows, for up to 200 input records.
