# Net Profit Waterfall – Sequential Input-Change Attribution

> Net Profit Waterfall – Sequential Input-Change Attribution is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Performs a sequential (waterfall) attribution analysis on net profit by changing each cost/revenue input from baseline to final values in declared field order, reporting the incremental effect of each change.

## 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 net-profit-waterfall-sequential-input-change-attribution-c0dda147 -d '<json body>'
```

Example prompt: Run a sequential waterfall attribution on net profit: before figures are revenue 10000, cost of sales 6000, operating expenses 2000, interest expense 200, tax expense 300; after figures are revenue 11000, cost of sales 6600, operating expenses 2200, interest expense 220, tax expense 330 — show me each input's incremental effect in order.

## When to prefer this

Choose this endpoint when you need an order-dependent, sequential (waterfall/bridge) attribution of net profit changes — where each input is changed one at a time from baseline to final in field declaration order and the incremental effect reported. Prefer this over a simultaneous sensitivity analysis when you want to understand the step-by-step contribution of each line item in a fixed sequence, such as for management reporting, board presentations, or period-over-period profit bridges. It is not suitable for real-time data, live financial feeds, or trade execution.

## Known failure modes

- Missing required fields in before or after objects returns a validation error
- Values outside the allowed range (±1,000,000,000,000) are rejected
- Non-numeric values for financial fields cause schema validation failure
- Payment of 0.01 USDC not completed results in 402 Payment Required response
- Providing inconsistent currencies across fields produces mathematically valid but economically meaningless results (no currency conversion is performed)

## How this service works

Net profit from supplied costs - Sequential input-change attribution: Change each input from baseline to final in declared field order, reporting each incremental effect; order dependent. Metric: Net profit from supplied costs. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded sequential input-change attribution report.

## Output

Returns a JSON object containing: the sequential waterfall attribution showing the incremental net profit effect of changing each input (revenue, cost of sales, operating expenses, interest expense, tax expense) from baseline to final values in declared field order; the net profit formula used; currency/units note; and limitations of the analysis.
