## 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 margin-of-safety-ordered-trend-analysis-287c2c8b -d '<json body>'
```

Example prompt: Can you fit a descriptive straight-line trend to my margin of safety data? I have 8 periods: actual sales were 10000, 11000, 10500, 12000, 11500, 13000, 12500, 14000 and break-even sales were 7000, 7200, 7100, 7500, 7300, 7800, 7600, 8000. Just the trend formula and direction — no forecast.

## When to prefer this

Choose this endpoint when you need a fast, bounded descriptive linear trend on margin-of-safety figures from your own supplied data — no external data feed, no forecast, no financial advice. Prefer it over generic regression APIs when you specifically want a pre-structured margin-of-safety framing with formula, units, and built-in limitations disclosure delivered as JSON for up to 200 equally-spaced periods.

## Known failure modes

- Fewer than 2 rows supplied — minimum of 2 observations required
- Non-positive actual_sales values (must be > 0)
- actual_sales or break_even_sales exceed maximum of 1,000,000,000,000
- More than 200 rows supplied — maxItems limit exceeded
- Inconsistent currency or reporting periods across rows — results may be misleading
- Payment failure — 0.01 USDC x402 payment not processed
