# Compare five companies' margins

Gross, operating and net margins for five companies over five fiscal years, side by side, with get_financials.

**Tools:** [`get_financials`](/developers/reference/get_financials) · **Calls:** 5

## Ask an assistant

> Using Fundalyze, compare the gross, operating and net margins of Apple, Microsoft, Alphabet, Amazon and Meta for the last five fiscal years. Show one table per margin, companies as rows, and note that their fiscal years end in different months.

The assistant makes one `get_financials` call per company with `metrics` set to the three margin keys, so each answer stays small.

## Or in code

Margins come precomputed as ratios (0.45 = 45%), so there is no arithmetic to do. The [data dictionary](/developers/dictionary) lists every key; `gross_margin`, `operating_margin` and `net_margin` are on the income statement.

```python title="margins.py"
import os

import requests

BASE = "https://api.fundalyze.ai/api/public/v1"
session = requests.Session()
session.headers["Authorization"] = f"Bearer {os.environ['FUNDALYZE_API_KEY']}"

TICKERS = ["AAPL", "MSFT", "GOOGL", "AMZN", "META"]
MARGINS = ["gross_margin", "operating_margin", "net_margin"]

table = {}  # (margin, ticker) -> {fiscal year: value}
for ticker in TICKERS:  # one call at a time per key
    response = session.get(
        f"{BASE}/get_financials",
        params={"ticker": ticker, "statement": "income", "metrics": MARGINS, "years": 5},
        timeout=60,
    )
    response.raise_for_status()
    data = response.json()["data"]
    for metric in data["metrics"]:
        table[metric["key"], ticker] = dict(zip(data["periods"], metric["values"]))

for margin in MARGINS:
    print(f"\n{margin}")
    for ticker in TICKERS:
        cells = table[margin, ticker]
        print(ticker.ljust(6), "  ".join(f"{year} {value:6.1%}" for year, value in cells.items() if value is not None))
```

## Read it carefully

- **Fiscal years differ.** `FY2025` is the fiscal year the company reports, which for Microsoft ends in June and for Apple in late September. `period_ends` in `data` gives each column's end date; compare like with like.
- **Some lines do not exist for some companies.** Banks and insurers have no gross margin; the value is `null`.
- Check any figure on the page in `link`, which opens the company's statements on fundalyze.ai.
