The most advanced caching proxy for AI APIs.
4 cache layers + Multi-Provider support = Maximum savings with zero code changes.
WORKS WITH ALL MAJOR AI PROVIDERS
The only proxy that combines all four caching strategies for maximum savings
Complete response caching – when someone asks the exact same question, the answer comes from our cache.
User A: "What is 2+2?" → API → Cached ✅User B: "What is 2+2?" → Cache HIT → Free & Instant! ⚡
✅ Best for: FAQs, repeated queries, popular prompts
Anthropic's built-in prompt caching – caches parts of your prompt like system instructions, tools, and long messages.
System prompt (1000 tokens) → Cached after first use ✅Next 100 questions → System prompt from cache → 90% cheaper!
✅ Best for: AI agents, coding assistants, long conversations
Meaning-based matching – finds similar questions even when worded differently using AI embeddings.
User A: "How much does shipping cost?" → API → Cached ✅User B: "What is the shipping price?" → Semantic match → Cache HIT! 🎯
✅ Best for: Support chats, varied user inputs, natural language
All layers combined – exact → semantic → prompt → API, in optimal order.
Step 1: Check exact match (fastest, 5ms)Step 2: Check semantic match (similar meaning, 50ms)Step 3: Use prompt caching (token savings, 90%)Step 4: Fallback to API → Cache everything!
✅ Best for: Maximum savings, enterprise usage
⚡ When combined: All 4 layers work together automatically
Your system prompt is cached (90% cheaper), identical questions are free (100% savings), AND similar questions are matched semantically (30-50% extra). Maximum savings = 95%+!
Stop switching between different APIs. One proxy. One integration. All providers.

If one provider is down, we automatically switch
Simple tasks routed to cheapest provider
Auto, cheapest, or specific provider choice
LM Studio, Ollama, any OpenAI-compatible endpoint
Simple, fast, and no code changes required
Just change your baseURL and use your proxy key. No complex integration.
Live dashboard showing exactly how much you save per request.
Your API keys are encrypted using AES-256. We never see them.
Opt-in to shared cache — benefit from other users' cached responses.
Cached responses in ~5ms vs ~2000ms from API. Semantic cache in ~50ms.
Create separate profiles for different projects — each with its own cache.
Run models locally on your own machine and still benefit from our 4-layer caching. Your local responses are cached – so repeated questions are instant, even offline!

// Before (direct to Anthropic)
const anthropic = new Anthropic({
apiKey: "sk-ant-your-real-key",
baseURL: "https://api.anthropic.com"
});
// After (via our 4-layer + multi-provider proxy)
const anthropic = new Anthropic({
apiKey: "YOUR_PROXY_KEY", // from your dashboard
baseURL: "https://aicacheoptimizer.com/api/proxy.php?key="
});That's it! All 4 cache layers + multi-provider support work automatically.

100 API calls with a 1000-token system prompt
| Scenario | Without Cache | Exact Only | Exact + Prompt | All 4 Layers |
|---|---|---|---|---|
| 100 identical questions | 100× cost | 1× cost | 1× cost | 1× cost |
| 100 similar questions (different wording) | 100× cost | 100× cost | 100× cost | ~10× cost (semantic match!) |
| AI agent with 50 turns (same system prompt) | 50× cost | 50× cost | ~5× cost (prompt cached!) | ~5× cost + semantic |
| TOTAL SAVINGS (mixed workload) | $100 | $50 (50%) | $30 (70%) | $5 (95% saved!) |
Everything you need to know
Exact Cache: Saves complete API responses for identical questions (100% free). Prompt Cache: Uses Anthropic's built-in feature to cache system prompts (90% token savings). Semantic Cache: Matches similar questions using AI embeddings (30-50% extra). Hybrid Cache: Combines all three for maximum savings (95%+).
Just one line! Replace your baseURL with our proxy URL and use your proxy key as the API key.
Yes! Your API keys are encrypted using AES-256 before storage. We never see them in plain text.
