## 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 inventory-turnover-ordered-trend-analysis-952f7b17 -d '<json body>'
```

Example prompt: I have 8 quarters of data for cost of sales and average inventory — can you fit a straight-line trend to the inventory turnover ratios and tell me the formula and whether the trend is improving? Here are the numbers: Q1 30000/5000, Q2 33000/5500, Q3 31000/5200, Q4 34000/5600, Q5 32000/5300, Q6 35000/5700, Q7 33000/5400, Q8 36000/5800.

## When to prefer this

Choose this endpoint when you need a simple, descriptive linear trend fitted to a historical sequence of inventory turnover observations (cost of sales ÷ average inventory) without needing a forecast, live market data, or financial advice. It is ideal for operations and supply chain analysts who want a formula-based summary of inventory efficiency direction over time from their own supplied figures.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 observations required
- More than 200 rows supplied — exceeds maxItems limit
- average_inventory value of 0 — violates exclusiveMinimum constraint causing division-by-zero
- Non-numeric or missing cost_of_sales or average_inventory fields
- Payment failure or insufficient USDC balance (x402 protocol)
