# Two-Component Kit Capacity – Local Finite-Change Elasticity

> Two-Component Kit Capacity – Local Finite-Change Elasticity 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).

Computes local finite-change elasticity for two-component kit capacity inputs, showing how kit yield sensitivity responds to small step changes in component inventory or kit ratios.

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 two-component-kit-capacity-local-finite-change-elasticity-19cb2ec5 -d '<json body>'
```

Example prompt: Can you run a local finite-change elasticity report for a two-component kit where I have 100 units of component A (2 per kit) and 90 units of component B (3 per kit), varying component_a_units with a 1% step?

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) local finite-change elasticity estimate for a two-component kit capacity model using retail inventory figures. It is purpose-built for small-step sensitivity analysis on kit assembly constraints and is ideal when you want to understand marginal yield sensitivity without needing live market rates, order execution, or platform access.

## Known failure modes

- Invalid field enum value (must be one of component_a_units, a_per_kit, component_b_units, b_per_kit)
- Baseline values out of allowed range (component units 0–1,000,000; kit ratios 1–1,000,000)
- step_percent outside allowed range (0.01–10)
- Missing required baseline fields returns validation error
- Payment failure or insufficient USDC balance blocks execution
- Zero component units may produce degenerate or undefined elasticity

## How this service works

Two-component kit capacity - Local finite-change elasticity: Local finite-change elasticity 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 local finite-change elasticity report.

## Output

Returns a bounded local finite-change elasticity report for the specified two-component kit configuration, including the elasticity coefficient showing how a small step-percentage change in the selected field affects total kit capacity. Limited to retail-supplied figures, up to 200 records per call.
