April 29, 2024What Free Host Providers do you Use for deploying RESTful API ?
It's not really an answer to your question, but I have a nice deployment on digital ocean for about $5/month (droplet and static IPv4). You can often get like $50 credits for free, meaning 10 months of free deployment. More on reddit.com

August 18, 2021What is a frontend-first backend?
A frontend-first backend gives you production-grade data, auth, and automations without standing up servers. ReqRes lets you create projects with collections, app users, magic-link auth, and logs so your frontend can ship with real data and stay production-ready.

Use a hosted test API like ReqRes. Get a free API key, add it as an x-api-key header, and send requests to endpoints like https://reqres.in/api/users. No backend setup, database, or server required.

I think one of the big issues when learning to program is the absolut lack of data and for most semi-useful tools you need at least some of. Do you know of any cool websites that provide real world data / lots of data that can be easily accessed with an API (JSON) call?

SpaceX and CoinGecko both have nice JSON endpoints with real data too. REST Countries is handy if you need country info like flags or population. If a site doesn’t have an API, you can still grab data using scrapingbee. You'l get clean HTML without worrying about captchas or proxies. What kind of data are you trying to work with?

The best free REST API I have come across is from the National Weather Service. I am, however, tired of playing with the weather. I am not looking for anything in specific, just something other than weather. I know there is https://www.data.gov , but there doesn't appear to be any good, up-to-date data available. It is entirely possible I am using those APIs incorrectly. So, please, would you mind passing along some good REST APIs for me to "play" with?
Thanks!
EDIT: I also use the APoD REST API, but that's getting a little old too.
