# Economic Order Quantity Distribution Histogram

> Economic Order Quantity Distribution Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Computes a distribution histogram of Economic Order Quantity (EOQ) values across multiple retail scenarios using supplied demand, order cost, and holding cost inputs.

## 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 economic-order-quantity-distribution-histogram-026902bd -d '<json body>'
```

Example prompt: Can you generate a distribution histogram of EOQ values across these 4 retail scenarios — annual demands of 1000 and 1100 units, order costs of $20 and $22, and holding costs of $2.00 and $2.20 per unit — using 10 bins?

## When to prefer this

Choose this endpoint when you need to understand the statistical distribution or spread of EOQ values across multiple retail scenarios in a single call, rather than computing a single EOQ value. It is ideal for batch scenario analysis, sensitivity testing across cost and demand parameters, or visualizing how optimal order quantities cluster — all with locally-calculated results and no dependency on live inventory systems or external platform data.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 rows required
- More than 200 rows supplied — exceeds maxItems limit
- annual_holding_cost_per_unit set to 0 — excluded by exclusiveMinimum constraint causing division-by-zero in EOQ formula
- bins value outside 1–30 range — rejected by schema validation
- Missing required fields (annual_demand, order_cost, annual_holding_cost_per_unit) in any row
- Payment not included or incorrect amount — x402 payment required at $0.01 USDC

## How this service works

Economic order quantity - Distribution histogram: Distribution histogram for Economic order quantity. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded distribution histogram deliverable.

## Output

A bounded distribution histogram showing how EOQ values are distributed across the supplied retail scenarios, organized into a specified number of bins (1–30). Each bin captures the frequency or count of EOQ values falling within that range, enabling visual and quantitative analysis of order quantity spread.
