# Days Payables Outstanding – Two-Input Scenario Grid

> Days Payables Outstanding – Two-Input Scenario Grid 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).

Calculates up to 100 combinations of two DPO input variables (average payables, credit purchases, period days) and returns a scenario grid with formula, units, and limitation notes.

## 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 days-payables-outstanding-two-input-scenario-grid-85635cde -d '<json body>'
```

Example prompt: Run a two-input DPO scenario grid with average_payables on the X axis ranging from [3000, 3500, 4000, 4500, 5000] and credit_purchases on the Y axis ranging from [20000, 22500, 25000, 27500, 30000], using a baseline of 365 period days, $4000 average payables, and $25000 credit purchases.

## When to prefer this

Choose this endpoint when you need to evaluate Days Payables Outstanding across a matrix of two varying inputs simultaneously (up to 10×10 = 100 combinations) rather than a single-point calculation. It is purpose-built for DPO scenario analysis with explicit formula and unit metadata returned, making it ideal for financial reporting, working capital modeling, and sensitivity analysis pipelines that require structured JSON output with invalid-combination handling.

## Known failure modes

- field_x and field_y set to the same variable — invalid distinct-field requirement
- credit_purchases baseline or Y-axis values set to 0 or negative (exclusive minimum) — reported as invalid combinations
- values_x or values_y arrays exceed 10 items — rejected
- period_days exceeds 3660 or below 1 — rejected
- missing required baseline fields — validation error
- payment of 0.01 USDC not completed — request not processed

## How this service works

Days payables outstanding - Two-input scenario grid: Calculate up to 100 combinations of two distinct supplied input fields, with invalid combinations reported. Metric: Days payables outstanding. 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 two-input scenario grid report.

## Output

A JSON object containing a grid of up to 100 DPO values across all combinations of the two chosen input axes, the DPO formula used, units, flagged invalid combinations (e.g. zero credit purchases), and stated limitations of the calculation.
