A real request and response

Here's what an actual API call looks like end to end — the request your app sends, and the JSON it gets back:

GET /forecast?city=London HTTP/1.1
Host: api.weather.com
Authorization: Bearer sk_live_8f4b2c... 
Accept: application/json

{
  "city": "London",
  "unit": "celsius",
  "current": {
    "temp": 14,
    "condition": "cloudy"
  },
  "forecast": [
    { "day": "Mon", "high": 16, "low": 9 },
    { "day": "Tue", "high": 18, "low": 11 }
  ]
}

That Authorization line is the next topic — and the one most worth getting right.
