## 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 net-margin-ordered-trend-analysis-b5c0ec42 -d '<json body>'
```

Example prompt: Fit a straight-line trend to my net margin data — I have 8 quarterly observations: revenue was 10000, 11000, 10500, 12000, 11500, 13000, 12500, 14000 and net profit was 1200, 1430, 1260, 1560, 1495, 1820, 1625, 1960. Give me the trend formula and tell me if margins are improving.

## When to prefer this

Choose this endpoint when you have a supplied historical series of net profit and revenue pairs and need a simple, descriptive linear trend fitted to the derived net margin — especially when you want a structured JSON result with the formula and caveats and do not need a forecast or live market data. It is well-suited for batch financial reporting workflows where profitability trend summaries are needed across multiple periods without requiring external data feeds.

## Known failure modes

- Fewer than 2 rows supplied — minimum observation count not met
- Revenue value is zero or negative — violates exclusiveMinimum constraint
- Row count exceeds 200 — maxItems limit breached
- Net profit or revenue values missing from a row — required field validation failure
- Non-numeric values passed for revenue or net_profit — schema type error
- Payment not confirmed — x402 payment required before response is returned
