# Warehouse Movements Equal-Width Histogram

> Warehouse Movements 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 2026-10-16).

Bins up to 200 warehouse movement records (received or dispatched units) into an equal-width histogram with a configurable number of bins for distribution analysis.

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 warehouse-movements-equal-width-histogram-dfea1357 -d '<json body>'
```

Example prompt: Take these 50 warehouse movement records and build an equal-width histogram for received_units using 10 bins so I can see how the receiving quantities are distributed across my locations.

## When to prefer this

Choose this endpoint when you have raw warehouse movement records (up to 200 rows) and need a quick frequency distribution of either received or dispatched unit quantities. It is ideal for on-the-fly analytics in agent pipelines that need distribution shapes without setting up a full BI stack. Prefer it over ranking or rebase endpoints when the goal is to understand spread and concentration across value ranges rather than relative ordering or indexed trends.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maximum input limit
- bins parameter outside 1–30 range — validation error
- Missing required fields (row_id, location, date, received_units, dispatched_units) in any row — schema validation failure
- date field not matching YYYY-MM-DD pattern — format error
- All values for the selected field are null — unable to compute histogram
- field value not one of 'received_units' or 'dispatched_units' — enum validation error

## How this service works

Warehouse movements - Equal-width histogram: Equal-width histogram for Warehouse movements. Up to 200 supplied typed records. Local numeric and data-quality processing; no external enrichment or forecasting. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded equal-width histogram deliverable.

## Output

Returns a frequency distribution as an equal-width histogram: each bin covers an equal numeric range of the selected field (received_units or dispatched_units), and each bin entry reports its lower bound, upper bound, and the count of records falling within that range. Up to 30 bins, computed locally without external enrichment.
