Authentication (PRO TIERS only)
Authentication is based on passing your API key as a header parameter to any request you make. This API key will be assigned to you when you register with RapidAPI.
Specifically, all requests will require the following header parameter:
x-rapidapi-key: YOUR_API_KEY
For example, here is a cURL REST request you could execute right from your local shell to find all cities in the US and Canada with a population over 100,000:
curl --get --include 'https://wft-geo-db.p.rapidapi.com/v1/geo/cities?countryIds=US,CA&minPopulation=100000' \
-H 'x-rapidapi-key: YOUR_API_KEY' \
-H 'x-rapidapi-host: wft-geo-db.p.rapidapi.com'
Note: Unless you specify an offset and limit, you will automatically get back the first 10 results. (Also, for the Basic plan, you are limited to 10 results at a time.)
