Stop paying markup on AI tools: bring your own API keys
Most AI tools charge you twice: once for the model, once for themselves. Your own key removes the second charge.
What does bring your own API key mean?
Bring your own key, or BYOK, means a tool runs AI models on your own account with a provider such as OpenAI, Anthropic or Google, instead of reselling that access to you. You create an API key with the provider, paste it into the tool once, and the provider bills you directly for what you use, at its own published rates.
What you are actually paying for today
When an AI product charges a monthly fee, part of it pays for the model calls it makes on your behalf and part is the tool's own margin. You rarely see the split. A plan can cover a small real model cost and keep the rest, or cap your usage so tightly that you hit a wall halfway through the month.
Use three or four of those tools and you pay three or four margins at once, on top of model costs you cannot see. That is why a stack of AI subscriptions feels expensive out of proportion to what you actually run.
How your own key changes the math
A tool that runs on your key steps out of the payment path. The provider bills you for what you run, and the tool has nothing to mark up because it never fronted the cost. You trade a fixed markup for metered spend you can see line by line.
- You pay the provider's real rate, not a plan price set high enough to cover heavy users.
- A quiet month costs you almost nothing in model usage.
- Every run is visible, so you can see which task or tool is the expensive one.
How do you get an API key?
- 1Pick a provider. OpenAI, Anthropic (Claude) and Google (Gemini) cover most business jobs.
- 2Create an account in the provider's developer console. This is separate from a ChatGPT or Claude chat subscription.
- 3Add billing or credit, and set a monthly spending limit so there are no surprises.
- 4Create a key, copy it once, and paste it into the tool. Treat it like a password.
It takes a few minutes per provider, once. The guides on BizWax.Ai walk through each provider's console screen by screen.
Is it safe to give a tool your API key?
It can be, if the tool handles it properly. Anyone holding your key can spend on your account, so check three things before you paste one in: the key is encrypted when stored, it is never shown back in full or sent to the browser, and you can delete it at any time. A spending limit set at the provider caps the damage if a key ever leaks.
How BizWax.Ai uses your keys
BizWax.Ai is built this way. You add your provider keys once and every tool on the platform uses them, with the provider billing you directly and nothing added on top. Keys are encrypted with AES-256-GCM before they are stored and never returned to the browser, so you only ever see the last four characters. One $20-a-month plan covers every tool, and everything you make is saved to one Library.
One account, your own keys, no markup on what you run.
