One unified API to access all AI models in the world.
Missing one? We add it within 48 hours.
Join developers building with every AI model
Two modes to fit your needs. Pick what works for your project.
We forward your requests to providers as-is. Use the native API format of OpenAI, Anthropic, or any provider. Your code stays familiar, you just change the base URL to api-hub.ai. Best when you want full control over provider-specific features.
One request format, one response format. We translate between you and every provider. Switch from GPT-4 to Claude to Gemini by changing one parameter. Best when you want to compare models or build provider-agnostic applications.
If a publicly available model isn't on api-hub.ai, tell us. We add it within 48 hours. No waiting for quarterly releases. The AI landscape moves fast, and so do we.
Connect once, access every model. No need to integrate each provider separately. One API key, one billing dashboard, one set of documentation.
Configure backup providers. If OpenAI is down, your request automatically routes to Claude or Gemini. Your app keeps working.
Zero markup on API costs. You pay exactly what providers charge, plus a flat platform fee. No percentage cuts, no hidden fees.
Text, images, speech, embeddings. We support every publicly available model. If it exists and has an API, we have it.
Define fallback chains. If your primary model times out or errors, we route to your backup automatically. Configure rules per endpoint.
One dashboard for all your AI usage. See costs per model, per endpoint, per project. Set budget alerts to avoid surprises.
OpenAPI spec available. SDKs for common languages. Or just use curl. We return clear error messages when things go wrong.
0% markup on AI provider costs. You only pay for usage and platform features.

Pre-Launch Special: Sign up now and get $1 in free credits for every $1 you add (up to $100 bonus). Use them with any AI provider.
You pay the exact provider cost (e.g., OpenAI charges $0.03/1K tokens, you pay $0.03/1K tokens). The Starter plan is completely free for up to 20 requests/day. Pro is $9/month for 10,000 requests/day with advanced features. Enterprise is $99/month for 1,000,000 requests/day. No hidden fees, no markup on API calls.
Yes. All you need to do is change the model parameter in your API call. Going from GPT-4 to Claude? Change "gpt-4" to "claude-3-opus". That's it. We handle all the formatting, authentication, and API differences behind the scenes.
With the Pro plan, you can configure automatic fallback rules. If your primary provider fails, we'll automatically route your request to your backup provider(s) without your app even knowing there was an issue. This feature alone has saved our users thousands in lost revenue.
We only store metadata (timestamps, model used, token count) for billing and analytics. Your actual request content and responses are never stored. They pass through our system encrypted and are immediately forwarded to/from the AI provider.
We support all publicly available AI models: OpenAI, Anthropic, Google, Mistral, Cohere, Stability AI, Replicate, ElevenLabs, Voyage, and more. If a model you need isn't available, let us know and we'll add it within 48 hours.
We offer a 14-day free trial of the Pro plan. If you're not satisfied, cancel anytime and you won't be charged. During the pre-launch credits bonus, credits are refundable and never expire.
Direct integration locks you into one provider's format. With api-hub.ai, you choose: use Direct Proxy mode to keep your existing code and just change the base URL, or use Unified mode for a consistent request/response format across all providers. Either way, you get failover, usage analytics, and the ability to switch models instantly.
Developers Love the Simplicity
"We switched from juggling 3 different AI providers to api-hub.ai. Integration time went from weeks to 45 minutes. The automatic fallback saved us during the last OpenAI outage."
Sarah Martinez
CTO at TechFlow
"The cost transparency is game-changing. We know exactly what we're paying and can easily A/B test different models to optimize for both quality and cost."
James Chen
Lead Engineer at DataSphere
"I built a production app in a weekend. The unified API means I don't have to learn each provider's quirks. It just works."
Alex Petrov
Solo Developer
"Switching between Claude and GPT-4 based on task complexity cut our AI costs by 40% without sacrificing quality. The API makes it trivial."
Maya Kapoor
Product Lead at Nexus AI
"The automatic failover is brilliant. When one provider goes down, our users don't even notice. That's the kind of reliability we need for production."
Robert Lee
DevOps Engineer at CloudSync
"Finally, one API key instead of five. Onboarding new developers takes minutes instead of hours. The documentation is clear and the examples just work."
