What people say after switching
“Underrated gem. I've tried a bunch of APIs and this one works really fast. Very underrated — I don't know why people don't know about this platform.”
“Replaced three separate API keys with one. The drop-in compatibility is real — zero code changes beyond the base URL.”
“Switched my entire side project in under 10 minutes. The latency is on par with calling OpenAI directly, and I'm paying a fraction.”
“I was burning $200/mo on API calls. This cut it to about $40 with zero changes to my code. Genuinely shocked it works this well.”
“My students needed API access for a course. Free tier covered every single one of them. This solved a real problem for us.”
“One key, all providers. I can now A/B test Claude vs GPT vs Gemini without juggling four dashboards and four billing accounts.”
“You are a game changer. You don't even know — you saved my bank balance today. Thanks a lot.”
“This is actually good. Why didn't I know about this earlier? Switched in five minutes and haven't looked back.”
“Exactly what I needed. One API key, all models, and my bill dropped immediately. Simple as it should be.”
“Was skeptical at first. Tried it on a side project, saved 75% on my monthly LLM spend. Now it's on everything I build.”
“I use this for prototyping with clients. Being able to switch models mid-demo without changing code is a superpower.”
“Setup took literally two minutes. Changed the base URL, dropped in the key, and everything just worked. Incredible.”
FAQ
Frequently asked questions
Everything you need to know about the product and billing.
How is this so much cheaper than official APIs?
We aggregate unused credits, utilize volume tier discounts, and intelligently route requests across a massive pool of API keys. We pass those wholesale savings directly to you, making it significantly cheaper than calling providers like OpenAI or Anthropic directly.
Are there subscription plans or a free tier?
Yes! We offer a completely free plan for verified users (up to 100k tokens/day) to get started. For heavy users, our Starter, Pro, and Max plans start at just $10/month and give you a fresh token allowance every 5 hours (up to 12M tokens) plus a weekly total, across all models.
What happens if I reach my plan's limit?
If you reach your 5-hour session or weekly limit, your one-time bonus tokens cover you first. After that, if you have credit, your account falls back to our ultra-cheap Pay-As-You-Go system and you pay only for exact token usage at discounted rates. Your session refills 5 hours after it starts, and the weekly total resets every Monday at 00:00 UTC.
Do I need to rewrite my code or use a new SDK?
Not at all. FreeAIapiKey acts as a 100% drop-in replacement. If you use the official OpenAI or Anthropic SDKs, simply change your baseURL to our endpoint and drop in your new API key. Zero code changes required.
Which models do you support?
Currently, we only support models from OpenAI and Anthropic, but we are actively integrating more providers. You will see new models and providers available on the platform very soon.
Is my data private and secure?
Yes. We act strictly as a high-speed proxy gateway. We do not store your prompts or completions, we do not log sensitive payload data, and your data is absolutely never used for training models.
What happens if a provider goes down or rate-limits you?
Our gateway features smart key rotation and automatic failover. If an underlying provider key hits a rate limit or fails, we seamlessly and instantly retry your request on a healthy key before you even notice a delay.
Is this reliable enough for my production app?
Absolutely. The platform is engineered for high-concurrency production workloads. We use Redis for sub-millisecond L1 caching, async connection pooling, and edge routing to ensure our gateway adds virtually zero latency overhead to your requests.
