Claude API: How to get a key and use the API

July 8, 2024 - I don't want all my credits to fly away by calling the pricey Claude 3 Opus, so I'm going to change the model value to claude-3-haiku-20240307.

r/ClaudeAI on Reddit: Use Claude 3 Opus from the API to prevent paying a flat $20/month for it

March 27, 2024 -

I highly recommend using Claude 3 Opus from the API, especially if you just want to try it out. It’s not free but the API doesn’t require an upfront flat fee and doesn’t have rate limits etc!

There’s some options for desktop like TypingMind.

For iOS I wanted to suggest my app called Pal Chat that lets you use your own API Key to chat with Claude, and it’s completely free to download: https://apps.apple.com/us/app/pal-ai-chat-client/id6447545085

(The app also has no backend and takes absolutely no usage data. You can verify this by going to the app privacy report in iOS settings!)

Okay... but Opus is $75 per million tokens. For someone that uses it as a chatbot (not night and day by any means), how does that stack up to $20/month (roughly)?

Connecting via the API is often cheaper as you are paying per-use. If you don't use $20 worth of service, then there's no need to be paying $20 per month. For desktop users, LibreChat is good and open source. Can connect to numerous APIs. Installation is slightly technical but clearly described. https://github.com/danny-avila/LibreChat

r/SillyTavernAI on Reddit: New to SillyTavern Can't find Claude 3 opus API keys in account

May 18, 2024 -

as the title says, I downloaded the sillytavern interface and have had it for like a day and while it's a lot for someone who is new to it. I keep seeing that I need a API key, however there is no API key in the account of claude 3 and i even have opus membership. Now what i found out is that it used to have them available before but apparently has had them removed from view. the API key were there before but now are hidden. how do i find a way around this as i like claude 3 opus and would prefer using this or would i have to find another model?

This post is confusing. If you pay 20 bucks per month for Claude you don't have an API key. An API key works with a plan where you are charged per token not per month (a token is around 75 percent of a word). If you have a Claude account for API use log into it and get your key.

i cancelled my openai subscription time ago and now i use places like openrouter, that has a lot of models (including claude). In last month i spent $5 , and it was way better than the torment of using the chat of openai. My apps are https://github.com/open-webui/open-webui and ST

r/ClaudeAI on Reddit: I made a Native iOS app that lets you chat with Claude 3 Opus for free using your own API Key

December 30, 2023 -

I wanted to share my iOS app that lets you chat with Claude 3 Opus for free! You use your own API key, and the app provides the chat interface.

Since the app is powered by your own API Key - that means there's no backend, and the app also supports on-device conversation history. This makes all your chats fully private and secure.

The app also offers API Key access to all the major LLMs like GPT-4 Turbo, Gemini Pro, Mistral Large etc.

Great app! Props for making an actually free iOS app, it's a rare sight these days sadly. I'd like to see Sonnet (and Haiku once it's out) added to the Other Models menu, Opus can get pricy and Sonnet is great for a lot of tasks.
