## 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-base-100-rebase-report-4d11eef5 -d '<json body>'
```

Example prompt: I have 4 periods of inventory data — for each I have average inventory and cost of sales. Period 1: 365 days, cost of sales $30,000, average inventory $5,000. Period 2: 402 days, cost of sales $33,000, average inventory $5,500. Period 3: 365 days, $30,000 cost of sales, $5,000 average inventory. Period 4: 402 days, $33,000 cost of sales, $5,500 average inventory. Rebase the Days Inventory Outstanding values to a Base-100 index using Period 1 as the base, and show me the formula and any limitations.

## When to prefer this

Choose this endpoint when you need to normalize Days Inventory Outstanding across multiple periods into a comparable Base-100 index series, particularly when the absolute DIO values differ in scale and you want to visualize or report relative change from a chosen reference period. It is ideal for trend analysis, period-over-period benchmarking, and presentation-ready indexed metrics rather than raw ratio lookups.

## Known failure modes

- Missing required fields (average_inventory, cost_of_sales, or period_days) returns a validation error
- cost_of_sales value of zero or negative triggers exclusiveMinimum validation failure
- Fewer than 2 rows provided returns a minItems validation error
- base_index referencing a position beyond the number of supplied rows returns an out-of-range error
- More than 200 rows exceeds maxItems limit
- Payment of 0.01 USDC not included triggers x402 payment-required response
