## Before you call it

1. Pass lat and lon. City, postal code and station lookups are accepted, but the docs recommend coordinates and mark station ID as use with caution
2. Read X-RateLimit-Remaining and X-RateLimit-Reset on each response. Daily quotas reset at 00:00 UTC and a spent quota returns 429 until then
3. Treat HTTP 204 with an empty body as no data found, not as an error
4. Split historical requests into ranges of one month or less. History needs the Plus plan or higher and has its own daily quota
5. Keep the key out of logs. It is part of the URL on every call, so always use https://api.weatherbit.io/v2.0

## Connect

```bash
pip install pyweatherbit
```

```bash
curl -s "https://api.weatherbit.io/v2.0/forecast/daily?days=16&key=API_KEY&lat=35.7796&lon=-78.6382"
