# Scene Geometry Equal-Width Histogram and Keyed Dataset Comparison

> Scene Geometry Equal-Width Histogram 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 2026-10-21).

Computes an equal-width histogram and a keyed dataset comparison for up to 200 scene geometry records (object_count, triangle_count) using local analytical engines.

## 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-equal-width-histogram-and-keyed-dataset-comparison-806c163f -d '<json body>'
```

Example prompt: Can you analyze the distribution of object_count across my scene geometry records and compare two datasets side by side? I have two groups of up to 50 rows each with asset_group, date, object_count, and triangle_count fields — use 10 bins for the histogram.

## When to prefer this

Choose this endpoint when you need local, stateless statistical analysis of 3D scene geometry metrics (object_count, triangle_count) — specifically when you want both a frequency histogram AND a keyed pairwise comparison between two geometry datasets in a single call. It is well-suited for 3D pipeline QA, asset complexity audits, and before/after geometry optimization comparisons on small-to-medium datasets (up to 200 rows). It does not perform predictions, live lookups, or external actions.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required row fields (row_id, asset_group, date, object_count, triangle_count) — validation error
- bins parameter outside 1–30 range — rejected
- Null values in numeric fields may affect histogram bin calculation
- Payment of 0.01 USDC not completed — 402 response returned
- Mismatched row_id keys between primary and comparison datasets — comparison report may show missing entries

## How this service works

Scene geometry — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + 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 independent analytical reports: (1) an equal-width histogram showing bin boundaries and row-count frequencies for the selected field (object_count or triangle_count) across up to 200 input rows, and (2) a keyed dataset comparison report matching rows by row_id between the primary and secondary datasets and highlighting differences in the selected metric. Both reports are computed locally with no external lookups.
