## 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-inventory-outstanding-target-gap-calculator-027194a5 -d '<json body>'
```

Example prompt: Calculate my days inventory outstanding using average inventory of $8,000, cost of sales of $50,000 over 365 days, and tell me the gap versus my target of 55 days.

## When to prefer this

Choose this endpoint when you need a fast, deterministic calculation of Days Inventory Outstanding measured against a specific numeric target, without needing forecasting, recommendations, or live data feeds. Ideal for agents automating financial reporting, inventory benchmarking, or supply chain KPI monitoring where the user supplies all raw figures.

## Known failure modes

- Missing required fields (average_inventory, cost_of_sales, period_days) returns a validation error
- cost_of_sales of zero triggers an exclusiveMinimum validation error (must be greater than 0)
- Values exceeding maximum bounds (e.g. cost_of_sales > 1,000,000,000,000) return a range validation error
- No target supplied defaults to 100, which may produce misleading gap results if not intended
- Payment failure or insufficient USDC balance returns a 402 error before processing
