# Expected vs. Received Payout Variance – Local Finite-Change Elasticity

> Expected vs. Received Payout Variance – 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 2026-10-20).

Computes local finite-change elasticity for expected-versus-received payout variance given retail figures, returning a bounded sensitivity report.

## 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 expected-vs-received-payout-variance-local-finite-change-elasticity-099ce60a -d '<json body>'
```

Example prompt: Can you run a local finite-change elasticity analysis on my retail payout variance? My baseline expected payout is 1000 and received payout is 1020 — use expected_payout as the field and a 1% step size.

## When to prefer this

Choose this endpoint when you need a bounded, local sensitivity estimate of how payout variance responds to marginal changes in either expected or received payout values using finite-difference methods on retail data. Prefer it over global elasticity or regression-based approaches when you want a lightweight, single-point sensitivity report rather than a full distributional or trend analysis.

## Known failure modes

- Missing or invalid baseline values (expected_payout or received_payout out of range ±1,000,000,000,000)
- step_percent outside allowed range of 0.01–10
- Invalid field enum value (must be 'expected_payout' or 'received_payout')
- Payment failure or insufficient USDC balance
- Service unavailable or rate limit exceeded
