# Two-Component Kit Capacity – Adjacent Period Changes

> Two-Component Kit Capacity – 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 2026-10-13).

Calculates period-over-period changes in two-component kit assembly capacity given supplied retail inventory figures across consecutive time periods.

## 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 two-component-kit-capacity-adjacent-period-changes-ecbaeb7a -d '<json body>'
```

Example prompt: I have four consecutive inventory snapshots for a kit that needs 2 of component A and 3 of component B per kit: period 1 has 100 A and 90 B, period 2 has 110 A and 99 B, period 3 has 100 A and 90 B, period 4 has 110 A and 99 B — can you calculate the adjacent period changes in kit capacity across those snapshots?

## When to prefer this

Choose this endpoint when you need a fast, inexpensive ($0.01 USDC) period-over-period delta report for two-component kit assembly capacity using supplied retail inventory figures, and you want a bounded result set (up to 200 records). Prefer it over general computation tools when the specific two-component kit capacity model (limiting-reagent logic with configurable per-kit ratios) matches your assembly scenario. Use the batch calculation sibling endpoint if you want absolute capacity figures rather than adjacent period changes.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 rows required for any adjacent comparison
- More than 200 rows submitted — exceeds maxItems limit
- component_a_units or component_b_units below 0 — violates minimum constraint
- a_per_kit or b_per_kit set to 0 — must be at least 1
- Missing required fields in any row object — schema validation error
- Payment not completed via x402 protocol — request rejected before processing

## How this service works

Two-component kit capacity - Adjacent period changes: Adjacent period changes for Two-component kit capacity. Supplied retail figures only, up to 200 records. No platform access, live rates or order execution. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded adjacent period changes report.

## Output

A bounded report (up to 200 records) showing the adjacent period-over-period changes in two-component kit capacity, computed from supplied retail inventory figures for each consecutive pair of input rows. Each result reflects how kit yield changed from one period to the next given component A and B unit counts and their per-kit requirements.
