## 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 operating-margin-ordered-trend-analysis-a8e41c0d -d '<json body>'
```

Example prompt: Can you fit a linear trend line to my operating margin data for the last 8 quarters? Here are my revenue and operating profit figures: Q1 $10M rev / $1.5M op profit, Q2 $11M / $1.7M, Q3 $10.5M / $1.6M, Q4 $12M / $2M, Q5 $11.5M / $1.8M, Q6 $13M / $2.2M, Q7 $12.5M / $2.1M, Q8 $14M / $2.5M — I want the trend formula and direction, no forecast needed.

## When to prefer this

Choose this endpoint when you need a simple, interpretable linear trend description of operating margin over a sequence of equally spaced observations, without requiring forecasting, live financial data, or complex statistical modeling. It is ideal for quick due diligence, investor reporting, or historical performance reviews where a formula and direction summary suffice.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 data points required
- Revenue value is zero or negative — revenue must be strictly greater than 0
- More than 200 rows supplied — exceeds maximum input size
- Malformed JSON input or missing required fields (operating_profit or revenue)
- Extremely large or inconsistent values may reduce statistical reliability
