## 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-capped-percentage-coupon-local-finite-change-elasticity-c592b62b -d '<json body>'
```

Example prompt: What's the local finite-change elasticity for a $150 list price item with a 30% discount coupon capped at $20 maximum discount — vary the list_price field with a 1% step?

## When to prefer this

Use this endpoint when you need a precise, bounded local elasticity measurement for a retail pricing model where a percentage coupon has a hard dollar cap — specifically when you want to quantify how a marginal change in list price, discount rate, or the cap itself propagates to the final customer price. Prefer it over general elasticity tools when the capped-coupon structure is the exact pricing mechanism in use.

## Known failure modes

- Invalid field enum value (must be list_price, discount_percent, or maximum_discount)
- list_price below 0 or above 1,000,000,000,000
- discount_percent outside 0–100 range
- maximum_discount below 0
- step_percent outside 0.01–10 range
- Exceeds 200 record limit
- Missing required baseline fields

## How this service works

Price after capped percentage coupon - Local finite-change elasticity: Local finite-change elasticity for Price after capped percentage coupon. 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 capped-coupon price model, quantifying how sensitively the post-coupon price responds to a small percentage change in the chosen field (list_price, discount_percent, or maximum_discount) around the supplied baseline values. The report covers up to 200 records and is limited to supplied retail figures with no live market data.
