Example: NASA API

NASA has several APIs to allow people from all over the world to access data from their databases. This enables people to create apps that can grab data directly from NASA's servers. The APIs are listed at NASA's website: https://api.nasa.gov/

Do you have to sign up for an API Key? No, if you’re staying within the DEMOKEY rate limits listed here `https://api.nasa.gov/api.html#demokey-rate-limits`
