One API.
Every AI model.
Stop wrangling ten different provider APIs. Quantum AI gives you a unified gateway to Claude, GPT-5, Gemini, Grok, DeepSeek, ElevenLabs, HeyGen, and more — with sessions, billing, and context management built in.
Architecture
Thin client to provider, in one stack
Everything your app needs — sessions, billing, routing, observability — between your code and the model.
SDKs — TypeScript · Python · Go · Rust · Swift · Kotlin — or any HTTP client. One key, one bill.
Stripe payments · Resend email · Cloud Armor WAF · deploy once, every client benefits instantly
SDKs
Pick your language
Every SDK wraps the same 100+ endpoints. Install, authenticate, ship.
npm install quantum-ai-sdkimport { QuantumClient, userMessage, responseText } from "quantum-ai-sdk";
const client = new QuantumClient("your-api-key");
const resp = await client.chat({
model: "claude-sonnet-4-6",
messages: [userMessage("Hello")],
});
console.log(responseText(resp));Endpoints

Tiers
Pricing that rewards commitment
Every tier uses the same infrastructure. The only difference is what you pay on top of provider costs.
Standard
- · 100+ endpoints
- · All 12 providers
- · Scoped API keys
- · Usage dashboard
Developer
- · Everything in Standard
- · Half the margin, on every call
- · Priority support
Enterprise
- · Everything in Developer
- · Near-cost pricing
- · SLA guarantees
- · Dedicated support
The math
It's simple
You pay what the provider charges, plus our margin. That's the whole formula. At $100 a month of Claude, GPT or Gemini on Standard you pay $125. Once you're past $50 a month you can apply for Developer, and the same $100 costs $112.50. Enterprise is negotiated from $500 a month and sits around 5%.
xAI and DeepSeek carry 30% on Standard, so those rows run a little higher. The margin is printed in every response header, so you can check the maths yourself.
| Monthly usage | Standard (25%) | Developer (12.5%) | Enterprise (5%) |
|---|---|---|---|
| $100/mo | $125 | $112.50 | n/a |
| $250/mo | $312.50 | $281.25 | n/a |
| $500/mo | $625 | $562.50 | $525 |
| $1,000/mo | $1,250 | $1,125 | $1,050 |
