Introducing AIsa's Unified Gateway: One API for 100+ AI Models
AIsa's Unified Model Gateway gives developers a single OpenAI-compatible endpoint to access over 100 large language models — from GPT-4o and Claude to Gemini, Qwen, and Deepseek — with pay-per-use pricing and zero vendor lock-in.
The Problem: Fragmented AI Access
Building AI-powered applications today means juggling multiple API keys, SDKs, billing dashboards, and authentication flows. Every model provider has its own interface, its own rate limits, and its own pricing structure. For teams building agentic systems that need to route between models dynamically, this fragmentation is a serious bottleneck.
The Solution: One Endpoint, 100+ Models
AIsa's Unified Model Gateway solves this with a single OpenAI-compatible REST API. Point your existing code at https://api.aisa.one/v1/chat/completions, swap in your AIsa API key, and you instantly have access to:
- GPT-4o, GPT-4 Turbo, GPT-3.5 — OpenAI's full lineup
- Claude 3.5 Sonnet, Claude 3 Opus — Anthropic's reasoning models
- Gemini 2.0 Flash, Gemini Pro — Google's multimodal models
- Qwen 2.5, Deepseek V3, Grok — Leading open-weight models
- Llama 3.1, Mistral Large — Meta and Mistral's latest
No SDK changes. No new authentication flows. Just change the base URL and model name.
Pay Only When Your Agent Acts
Traditional API subscriptions charge monthly minimums whether you use them or not. AIsa uses pure pay-per-use pricing — you pay only for the tokens your agents actually consume. New accounts start with $5 in free credits, so you can evaluate the platform at zero risk.
Getting Started
curl https://api.aisa.one/v1/chat/completions
-H "Authorization: Bearer YOUR_AISA_KEY"
-H "Content-Type: application/json"
-d '{"model": "gpt-4o", "messages": [{"role": "user", "content": "Hello!"}]}'
curl https://api.aisa.one/v1/chat/completions
-H "Authorization: Bearer YOUR_AISA_KEY"
-H "Content-Type: application/json"
-d '{"model": "gpt-4o", "messages": [{"role": "user", "content": "Hello!"}]}'
That's it. One API key, one endpoint, 100+ models. Visit docs.aisa.one to get started, or explore the AIsa Marketplace to test models in the playground.
What's Next
We're expanding the gateway with real-time streaming optimizations, function calling support across all providers, and automatic model fallback routing. Stay tuned for updates.
