Bring Your Own Keys. Keep Control.

Unlike API resellers who add markup fees, Costbase uses YOUR API keys directly. We add intelligence - you keep control.

  • Direct billing - pay providers directly
  • Your rate limits stay intact
  • Enterprise discounts? Keep them.
  • Your data privacy agreements apply
  • Zero per-token markup fees

How it works:

1

Configure your provider API keys in Costbase

2

Point your OpenAI SDK to Costbase gateway

3

We route intelligently using YOUR keys

Three Routing Strategies Working Together

Right model. Right cost. Every time.

Cost-Based

Analyzes query complexity and routes to the cheapest model that meets quality threshold

Semantic

Uses embeddings for task-aware routing—coding to GPT-4o, creative to Claude, translation to Gemini

Performance

Optimizes for latency and quality based on real-time provider benchmarks

Cost intelligence, not cost cutting

Drop-in replacement for OpenAI SDK. Just change the base URL and let intelligence take over.

Intelligent Routing

Three routing strategies (cost, semantic, performance) analyze every request and pick the optimal model automatically.

Semantic Caching

AI-powered caching understands query intent. "What is ML?" and "Explain machine learning" return cached results.

Transparent ROI Proof

Show exactly how much you saved vs direct API usage. Breakdown by cache savings vs routing savings.

Automatic Failover

Seamless fallback between providers. Never miss a request due to rate limits or outages.

Budget Controls

Set limits per API key. Get alerts before overages. Prove ROI to finance with predictive forecasting.

Model Benchmarking

Continuous benchmarking on YOUR data. Personalized routing based on your actual usage patterns.

ENTERPRISE RELIABILITY

Never Miss an SLA

Built-in redundancy, automatic failover, and real-time monitoring keep your AI services running—even when providers go down.

Automatic Failover in <100ms

If OpenAI goes down, we route to Anthropic or Google instantly. Configure up to 3 provider fallbacks per request.

Real-Time SLO Monitoring

Track uptime, latency (p50/p95/p99), and error rates. Get instant alerts when SLOs are violated.

Circuit Breaker Pattern

Automatically stops routing to failing providers and retries with exponential backoff. No manual intervention needed.

Stop Overpaying for LLM APIs

Most teams overpay 30-80% because they use expensive models for every query, can't cache effectively, and have no visibility into spend.

Costbase fixes all of this. Choose your deployment.
