## 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-histogram-191293f5 -d '<json body>'
```

Example prompt: Take these 8 quarters of payables data — average payables ranging from $3M to $6M, credit purchases from $18M to $40M, all on 90-day periods — and bin the Days Payables Outstanding values into 10 equal-width histogram buckets so I can see the distribution.

## When to prefer this

Choose this endpoint when you need to understand the statistical distribution of Days Payables Outstanding across a batch of observations — not just a single value. It is ideal for benchmarking payment behavior over time, auditing DPO spread across business units or suppliers, or preparing histogram data for visualization. Use the single-calculation sibling endpoint instead when you only need one DPO figure.

## Known failure modes

- Fewer than 2 rows supplied — minimum is 2 observations
- credit_purchases value of 0 causes division by zero (excluded via exclusiveMinimum)
- More than 200 rows supplied exceeds maximum input limit
- Bins value outside 1–30 range causes validation error
- Missing required fields (average_payables, credit_purchases, period_days) per row causes rejection
- Non-numeric or negative values for financial figures fail schema validation
