Quickstart

1. Create your account

Head to arrays.org and sign up with email, Google, or GitHub.

2. Copy your API key

In the dashboard, your key is shown immediately — no email verification required to start.

Treat your API key like a password. Never commit it to git. Use a .env file or your platform’s secret manager.

3. Make your first call

cURL
Python
Node.js

curl "https://data-tools.prd.arrays.org/api/v1/stocks/company/detail?symbol=AAPL" \
  -H "X-API-Key: $ARRAYS_API_KEY"

import os, requests

r = requests.get(
    "https://data-tools.prd.arrays.org/api/v1/stocks/company/detail",
    headers={"X-API-Key": os.environ["ARRAYS_API_KEY"]},
    params={"symbol": "AAPL"},
)
print(r.json())

const res = await fetch(
  "https://data-tools.prd.arrays.org/api/v1/stocks/company/detail?symbol=AAPL",
  { headers: { "X-API-Key": process.env.ARRAYS_API_KEY } }
);
console.log(await res.json());

You should see a JSON envelope:

{
  "success": true,
  "data": [
    {
      "symbol": "AAPL",
      "name": "Apple Inc.",
      "sector": "Technology",
      "industry": "Consumer Electronics",
      "exchange": "NASDAQ",
      "market_cap": 4629454611200,
      "pe_ratio": 37.77,
      "eps": 8.27
    }
  ],
  "request_id": "ee12ed44-81a0-4496-958c-d87a1b4048ac"
}

Every Arrays endpoint returns this envelope. data is always an array.
