# Rig Complexity — Category Frequencies + Equal-Width Histogram

> Rig Complexity — Category Frequencies + Equal-Width Histogram 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).

Analyzes rig complexity records (bone_count and constraint_count) by computing category frequencies and an equal-width histogram for up to 200 rows, returning two independent statistical reports.

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-category-frequencies-equal-width-histogram-4ecfe233 -d '<json body>'
```

Example prompt: Can you analyze the bone count distribution for my rig records and give me a category frequency report plus a 10-bin equal-width histogram? Here are my rows: row-1, group-a, 2026-10-01, bone_count=12, constraint_count=3; row-2, group-b, 2026-10-02, bone_count=45, constraint_count=8; row-3, group-a, 2026-10-03, bone_count=22, constraint_count=5.

## When to prefer this

Choose this endpoint when you need quick statistical profiling (frequency distribution + histogram) of 3D rig complexity metrics (bone counts or constraint counts) from your own supplied data, without requiring any external database, live lookup, or prediction. It is ideal for pipeline audits, rig complexity benchmarking, and asset group comparisons when you have up to 200 rows of rig records and want two reports in a single low-cost call.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes validation failure
- Missing required fields (row_id, asset_group, date, bone_count, constraint_count) causes schema rejection
- bins parameter outside 1–30 range returns validation error
- field value not in enum ['bone_count','constraint_count'] causes rejection
- All null values for the selected field may produce empty or degenerate histogram

## How this service works

Rig complexity — Category frequencies + Equal-width histogram: Category frequencies + Equal-width histogram 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

Two independent analytical reports: (1) a category frequency table showing how often each category or value range appears in the selected field (bone_count or constraint_count), and (2) an equal-width histogram with the requested number of bins (1–30, default 5), both computed locally from the supplied rows without any external lookup or prediction.
