# Supplied Stockout Cost – Adjacent Period Changes

> Supplied Stockout Cost – Adjacent Period Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Calculates adjacent period-over-period changes in supplied stockout cost from unfilled units and cost-per-unit inputs, returning a local computation with no live inventory access.

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 supplied-stockout-cost-adjacent-period-changes-5eb3451b -d '<json body>'
```

Example prompt: I have two periods of retail stockout data — period 1 had 10 unfilled units at $5 each, period 2 had 11 unfilled units at $5.50 each — can you compute the adjacent period changes in stockout cost for me?

## When to prefer this

Use this endpoint when you need a fast, local, offline computation of stockout cost changes between adjacent time periods from supplied retail figures — no live inventory system, ERP integration, or account credentials needed. Ideal for scenario analysis, reporting, or batch calculations where the user already has unfilled unit counts and cost-per-unit figures and wants period-over-period deltas quickly and cheaply.

## Known failure modes

- Fewer than 2 rows supplied — minimum of 2 rows required for adjacent period comparison
- unfilled_units or cost_per_unfilled_unit values out of range (negative or exceeding 1e12) — validation error
- More than 200 rows submitted — maxItems limit exceeded
- Missing required fields unfilled_units or cost_per_unfilled_unit in any row — schema validation failure
- Payment not confirmed via x402 protocol — request rejected before computation

## How this service works

Supplied stockout cost - Adjacent period changes: Adjacent period changes for Supplied stockout cost. 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 adjacent period changes deliverable.

## Output

Returns a structured deliverable showing the period-over-period (adjacent period) changes in computed stockout cost for each consecutive pair of input rows, derived from unfilled_units multiplied by cost_per_unfilled_unit, with no live inventory or platform data involved.
