# Price After Percent Discount — Local Finite-Change Elasticity

> Price After Percent Discount — 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 2026-10-24).

Computes how the final discounted price changes when either list price or discount percentage shifts by a small finite step, providing local elasticity for retail discount scenario analysis.

## 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 price-after-percent-discount-local-finite-change-elasticity-ee3fd98d -d '<json body>'
```

Example prompt: What's the local finite-change elasticity of the discounted price if I start with a list price of $150 and a 25% discount, and I want to see how the final price shifts when the discount_percent changes by a 0.5% step?

## When to prefer this

Choose this endpoint when you need a local, finite-difference sensitivity estimate for a simple percent-discount pricing model — specifically how the post-discount price responds to small perturbations in either the list price or the discount rate. It is ideal for lightweight retail scenario analysis, pricing model audits, or agent-driven margin planning where you only have the list price and discount percentage and need no live platform data.

## Known failure modes

- Baseline values missing required fields (list_price or discount_percent) returns a validation error
- discount_percent out of range [0,100] or list_price negative returns a schema violation error
- step_percent below 0.01 or above 10 triggers a range constraint error
- Invalid field enum value (not list_price or discount_percent) causes a bad request response
- Payment failure or insufficient USDC balance prevents call execution

## How this service works

Price after percent discount - Local finite-change elasticity: Local finite-change elasticity for Price after percent discount. 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 local finite-change elasticity deliverable.

## Output

Returns a local finite-change elasticity value quantifying how much the final discounted price changes per unit step in the chosen input field (list_price or discount_percent), computed around the provided baseline values. The response is a bounded, locally-scoped scalar or structured calculation result — no live inventory, platform fees, or order data is included.
