## Before you call it

1. Register an application and subscribe it to the Global Spot plan first. The key is tied to that order and shown once
2. Send the key in the apikey header with Accept: application/json, and latitude and longitude as query parameters
3. Add excludeParameterMetadata=true to drop the parameter descriptions from every response
4. Pick the timestep by need. hourly covers 48 hours, three-hourly 168, daily 7 days, and each call counts against the daily limit
5. Stop on a 429. The limit is daily and resets at 00:00 UTC

## Connect

```bash
curl -H "apikey: $METOFFICE_API_KEY" -H "Accept: application/json" "https://data.hub.api.metoffice.gov.uk/sitespecific/v0/point/hourly?latitude=51.51&longitude=-0.13&excludeParameterMetadata=true&includeLocationName=true"
```
