Example prompt: I have 8 quarters of data — can you give me a full distribution summary of our days sales outstanding, including quantiles and standard deviation? Here are the rows: period 90 days, net credit sales 500000, average receivables 75000; period 90, sales 480000, receivables 82000; period 90, sales 510000, receivables 70000; period 90, sales 495000, receivables 78000; period 90, sales 520000, receivables 85000; period 90, sales 470000, receivables 69000; period 90, sales 505000, receivables 80000; period 90, sales 490000, receivables 76000.

## When to prefer this

Choose this endpoint when you have multiple DSO observations (2–200) and need a statistical distribution summary — quantiles and population standard deviation — rather than a single-point calculation. It is ideal for trend analysis, benchmarking across periods or business units, and preparing executive-level receivables reports. Prefer it over single-calculation endpoints when spread and variability of collection performance matter, not just the mean.

## Known failure modes

- Fewer than 2 rows supplied — minimum observation count not met
- Any row missing required fields (average_receivables, net_credit_sales, or period_days)
- net_credit_sales set to zero or negative — exclusiveMinimum constraint violated
- More than 200 rows supplied — exceeds maxItems limit
- period_days outside the 1–3660 range — rejected by schema validation
- Numeric values exceeding 1 trillion — maximum constraint violation
- Payment of 0.01 USDC not completed — request rejected before processing
