# Working Capital Sequential Input-Change Attribution

> Working Capital 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 2026-11-01).

Performs a sequential (waterfall) attribution analysis showing how each input change — current assets then current liabilities — incrementally drives the change in working capital from a baseline to a final state.

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 working-capital-sequential-input-change-attribution-119a2811 -d '<json body>'
```

Example prompt: My current assets went from 20,000 to 22,000 and current liabilities went from 10,000 to 11,000 — can you run a sequential waterfall attribution to show how each of those changes individually drove the overall shift in working capital?

## When to prefer this

Choose this endpoint when you need to understand which specific working capital input (current assets or current liabilities) drove a change, and in what order — particularly for waterfall/bridge chart analysis, CFO reporting, or variance explanations. Prefer this over a simple before-and-after comparison when the sequential, order-dependent decomposition of each driver's marginal contribution matters. Use when you have exactly two inputs (current assets and current liabilities) in two states (before and after) and need a structured attribution JSON rather than just a delta.

## Known failure modes

- Missing required 'before' or 'after' objects returns a validation error
- Values outside the 0–1,000,000,000,000 range are rejected
- Non-numeric values for current_assets or current_liabilities cause a schema error
- Identical before and after inputs return zero attribution with no meaningful decomposition
- Payment of 0.01 USDC not completed blocks the request via x402 protocol

## How this service works

Working capital - Sequential input-change attribution: Change each input from baseline to final in declared field order, reporting each incremental effect; order dependent. Metric: Working capital. 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

A JSON response containing a step-by-step sequential attribution report that changes each input (current assets first, then current liabilities) from baseline to final values in declared field order, reporting the incremental effect of each change on working capital, along with the formula used, units, and known limitations of the order-dependent approach.
