## 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-before-after-comparison-calculator-fd22da71 -d '<json body>'
```

Example prompt: Compare our days payables outstanding: before we had average payables of $4,000 and credit purchases of $25,000 over 365 days, and after we had average payables of $4,400 and credit purchases of $27,500 over 402 days — show me the absolute and relative change.

## When to prefer this

Use this endpoint when you need a structured, formula-documented before-and-after comparison of Days Payables Outstanding between two specific periods, rather than a standalone DPO calculation. It is ideal for finance agents preparing variance reports, audits, or policy impact analyses where both the raw change and percentage change are required in a single response with metadata about the formula and its limitations.

## Known failure modes

- credit_purchases of zero causes division-by-zero error (excluded by exclusiveMinimum constraint)
- period_days outside 1–3660 range returns validation error
- missing required fields (average_payables, credit_purchases, period_days) returns schema error
- values exceeding 1,000,000,000,000 fail maximum constraint
- non-numeric inputs rejected by type validation
