## 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-distribution-summary-calculator-0dc67ac1 -d '<json body>'
```

Example prompt: Can you run a distribution summary on these 6 DPO observations — average payables of $4,000 against credit purchases of $25,000 over 365 days, and $4,400 against $27,500 over 402 days (repeat that pattern three times total) — and give me the quantiles and standard deviation?

## When to prefer this

Choose this endpoint when you need a statistical distribution summary (quantiles + standard deviation) across multiple DPO observations from your own supplied data, rather than a single DPO point calculation. It is purpose-built for batch financial metric analysis where you already hold the raw payables and credit purchase figures and want a bounded, reproducible statistical report. Prefer alternatives if you need live financial data, real-time feeds, or financial advice.

## Known failure modes

- Fewer than 2 rows provided — minimum array size not met
- credit_purchases set to zero — field requires exclusiveMinimum > 0
- More than 200 rows submitted — exceeds maxItems limit
- Non-numeric values in average_payables or credit_purchases fields
- period_days outside the 1–3660 day range — validation error
- Missing required fields (average_payables, credit_purchases, or period_days) on any row
- Payment of 0.01 USDC not settled via x402 — request rejected
