TokenMix

TokenMix.ai is a unified AI API gateway that gives developers access to 100+ AI models through a single OpenAI-compatible endpoint.

Instead of managing separate API keys, billing accounts, and SDKs for OpenAI, Anthropic, Google, DeepSeek, and Meta, you integrate once with TokenMix and switch between models by changing one parameter in your request.

How it works:

Sign up and get one API key
Point your existing OpenAI SDK at TokenMix's endpoint
Access GPT-5.4, Claude Sonnet 4.6, Gemini 2.5, DeepSeek V4, Llama 4, and 100+ other models
Pay only for what you use — no monthly fees, no minimum spend
Key features:

OpenAI-compatible API — drop-in replacement, no code changes needed if you already use the OpenAI SDK
99.9% uptime with automatic failover across providers
Real-time pricing — compare model costs before you call
Smart routing — send each task to the cheapest or fastest model automatically
Unified billing — one invoice for all providers
Pay-as-you-go — no subscriptions, no commitments
Who it's for:

Developers building AI-powered apps who want multi-model flexibility
Startups that need to keep API costs low while accessing frontier models
Teams comparing models (A/B testing GPT vs Claude vs Gemini) without managing multiple integrations
Production workloads that need failover — if one provider goes down, traffic routes to another automatically
Why not just use OpenAI/Anthropic directly?
You can. But when you need to test a different model, add a fallback, or cut costs by routing simple tasks to cheaper models, you'd need to integrate each provider separately. TokenMix handles that with one integration.
