# Scene Geometry Secondary-Measure Weighted Mean and Keyed Dataset Comparison

> Scene Geometry Secondary-Measure Weighted Mean and Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Computes a secondary-measure weighted mean and performs a keyed dataset comparison on up to 200 scene geometry records (object_count, triangle_count) using local analytics — no external lookups or predictions.

## 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-secondary-measure-weighted-mean-and-keyed-dataset-4bdf9d28 -d '<json body>'
```

Example prompt: Can you run a weighted mean analysis on my scene geometry data using triangle_count as the secondary measure, and compare it against our reference dataset? I have two sets of up to 50 rows each, grouped by asset_group (group-a and group-b), with dates in YYYY-MM-DD format.

## When to prefer this

Choose this endpoint when you need both a weighted-mean statistic and a keyed cross-dataset comparison on scene geometry data (object_count, triangle_count) in a single low-cost call. It is best suited for 3D asset pipeline QA, render scene audits, and geometry optimization validation workflows where you already have the data locally and need fast, deterministic analytics without external API dependencies. Prefer it over general-purpose analytics tools when your data fits the scene geometry schema and you want both reports bundled for $0.01 USDC.

## Known failure modes

- Rows exceed 200-item limit — request rejected
- Missing required fields (row_id, asset_group, date, object_count, triangle_count) — validation error
- Date field does not match YYYY-MM-DD pattern — schema validation failure
- Null values in numeric fields may affect weighted mean calculation
- Mismatched row_ids between primary and comparison datasets reduces comparison coverage
- Payment not processed — x402 payment required before response is returned

## How this service works

Scene geometry — Secondary-measure weighted mean + Keyed dataset comparison: Secondary-measure weighted mean + Keyed dataset comparison 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) a secondary-measure weighted mean calculation where one geometry metric (object_count or triangle_count) is weighted by the other across the supplied rows, and (2) a keyed dataset comparison that aligns rows from the primary and secondary datasets by row_id to surface differences — all computed locally with no external data sources.
