r/ClaudeAI on Reddit: I have never used an API. What’s the easiest way to use Claude’s?
September 10, 2024 -
Ive searched this subreddit for answers and I’ve also asked Google, Copilot, and free Claude. I’m sure the answers are out there, so please forgive me that I can’t find them.
Hence I ask for your help. What’s the easiest way for a programming noob to use the Claude API? All I want initially is to ask questions via the API, similar to the subscription version. I want to use the API vs subscription because maybe it’ll be cheaper and I also just want experience with it.
I signed up for an account and have purchased API tokens. I have an API key. But I’m struggling finding concise directions on how to use it.
I’m familiar with the $20/month subscription and want to become familiar with the API as well.

I’ve been using claude for a while now and I’ve always used the chat version but every other post/comment I see on this sub has people using it through an API. What exactly is it? What are the differences or benefits compared to using the chat version? Is it hard to set it up?
TIA

APIs are typically used when creating an app (say you wanted to create a chatbot for your company). One big difference is you pay by the token (which is similar to saying you pay by the word) - both input and output. For an expensive model like Opus, that can be a mountain of money. But since you're paying that way, you don't run into the message caps that the chat interface limits you too. > Is it hard to set it up It depends I guess. API stands for "Application Programming Interface" - they're designed for programmers. If you don't have any experience with programming, then yeah, you're probably going to struggle. Hopefully this helps a bit. Let me know if you have any more questions : )

There's kind of two things. There's the API playground and the API. The API playground is pretty similar to using the normal chat version that everyone uses, it's just a bit more complicated, but has more options... and it charges you as you go per message. If you're talking about using the API, it's when you integrate claude 3 into software or programs. It could be something like an app. I programmed some python code to input stuff from word documents into the claude api for example (well, I didn't actually write the code, the AI wrote the code)... but this is what you use the API for.
