# Scene Geometry Analytics — Adjacent Row Changes & Secondary-Measure Weighted Mean

> Scene Geometry Analytics — Adjacent Row Changes & Secondary-Measure Weighted Mean 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).

Computes adjacent row changes and secondary-measure weighted mean statistics for scene geometry records (object_count, triangle_count) supplied by the caller.

## 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 scene-geometry-analytics-adjacent-row-changes-secondary-measure-e775d95b -d '<json body>'
```

Example prompt: Can you run adjacent row change analysis and secondary-measure weighted mean on my scene geometry data — I have 4 rows with object_count and triangle_count values across asset groups group-a and group-b from 2026-10-01 to 2026-10-04, and I want to analyze object_count?

## When to prefer this

Choose this endpoint when you need fast, local analytical computation on scene geometry data (object_count and triangle_count) specifically requiring both adjacent row delta analysis and secondary-measure weighted mean — no external data lookups or predictions are needed. Ideal for 3D asset pipelines, game development workflows, or rendering audits where you supply your own tabular geometry records and need two complementary statistical reports in a single low-cost call.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected
- Missing required fields (row_id, date, asset_group, object_count, triangle_count) will cause validation errors
- Date fields not matching YYYY-MM-DD pattern will be rejected
- Null values in both object_count and triangle_count may produce undefined weighted mean
- Invalid field enum value (anything other than object_count or triangle_count) will fail validation
- Empty rows array will be rejected (minItems: 1)

## How this service works

Scene geometry — Adjacent row changes + Secondary-measure weighted mean: Adjacent row changes + Secondary-measure weighted mean for supplied scene geometry records (object_count, triangle_count). 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 analytical reports: (1) an adjacent row changes report showing delta values between consecutive rows for the selected field (object_count or triangle_count), and (2) a secondary-measure weighted mean report summarizing the weighted average of the selected field across all supplied rows, using the complementary measure as the weight. Covers up to 200 input rows per call.
