# Rig Complexity Equal-Width Histogram + Missing Value Fill

> Rig Complexity Equal-Width Histogram + Missing Value Fill 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).

Generates equal-width histogram distributions and fills missing values for rig complexity data (bone_count, constraint_count) across 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-equal-width-histogram-missing-value-fill-00f25b8d -d '<json body>'
```

Example prompt: Analyze the distribution of bone counts and constraint counts for my rig dataset — use 10 histogram bins and fill any missing values with the median. Here are the rows: [{"row_id":"rig-1","asset_group":"hero","date":"2024-01-15","bone_count":120,"constraint_count":45},{"row_id":"rig-2","asset_group":"npc","date":"2024-01-16","bone_count":null,"constraint_count":30}].

## When to prefer this

Choose this endpoint when you need fast, local statistical analysis of 3D rig complexity metrics (bone counts, constraint counts) without sending data to an external ML or BI service. It is ideal for small-to-medium datasets (up to 200 rows) where you want both a histogram distribution and missing-value imputation in a single call. Prefer this over general-purpose analytics APIs when your data is specifically structured as rig asset records with bone_count and constraint_count fields.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- bins value out of range (must be 1–30) causes rejection
- All values for selected field are null — histogram cannot be computed
- row_id missing or empty string causes validation error
- field enum value not recognized (must be bone_count or constraint_count)

## How this service works

Rig complexity — Equal-width histogram + Explicit missing-value fill: Equal-width histogram + Explicit missing-value fill 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 analytical reports: (1) an equal-width histogram showing bin ranges and row counts for the selected numeric field (bone_count or constraint_count), and (2) a missing-value fill report detailing which rows had nulls and what values were substituted using the chosen method (zero, mean, or median). Both reports are computed locally from the supplied rows with no external lookups.
