## When to prefer this

Choose this endpoint when you need a quick, single-record DPO calculation with formula transparency and unit documentation included in the response. Ideal for agents automating financial reporting, accounting workflows, or benchmarking payable efficiency without needing a full financial data platform. Best for one-off or per-record calculations rather than bulk batch processing.

## Known failure modes

- credit_purchases must be greater than 0 (exclusiveMinimum), otherwise division by zero error
- period_days out of range (must be 1–3660) returns validation error
- average_payables or credit_purchases exceeding 1,000,000,000,000 rejected by schema
- Missing required fields (average_payables, credit_purchases, period_days) returns error
- Payment failure (insufficient USDC) results in no calculation being returned
