# Rig Complexity Histogram & Correlation Analyzer

> Rig Complexity Histogram & Correlation Analyzer is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Computes an equal-width histogram and two-measure correlation for rig complexity data (bone_count, constraint_count) over up to 200 rows

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 rig-complexity-histogram-correlation-analyzer-c59dfe5f -d '<json body>'
```

Example prompt: Can you run a rig complexity analysis on my animation assets — use 10 bins for the histogram on bone_count, and also get the correlation between bone_count and constraint_count? Here's my data: row-1 (group-a, 2024-01-01, bones=45, constraints=12), row-2 (group-b, 2024-01-02, bones=120, constraints=34), row-3 (group-a, 2024-01-03, bones=78, constraints=20).

## When to prefer this

Choose this endpoint when you have rig complexity data (bone counts and constraint counts) for animation assets and need both a distributional view (histogram) and a relational view (correlation) in a single, low-cost call. Ideal for animation pipeline QA, asset audits, and technical director reporting where you have up to 200 rig records ready to supply and need fast local statistical computation without any external data lookup.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, date, bone_count, constraint_count, asset_group) causes validation error
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- Bins value outside 1–30 range causes parameter error
- All-null values in numeric fields may produce undefined correlation result

## How this service works

Rig complexity — Equal-width histogram + Two-measure correlation: Equal-width histogram + Two-measure correlation for supplied rig complexity records (bone_count, constraint_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 statistical reports: (1) an equal-width histogram showing frequency distribution of the selected field (bone_count or constraint_count) across the specified number of bins, and (2) a two-measure correlation report quantifying the relationship between bone_count and constraint_count across all supplied rows.
