Tokonomics
Tokonomics is an AI cost metering proxy that sits between your app and any LLM provider. One URL change gives you real-time cost tracking, budget alerts, and hard spending caps across OpenAI, Anthropic, DeepSeek, Google Gemini, Mistral, Groq, and more.
How it works: Replace your LLM base URL with Tokonomics, keep your existing code. Every API call is logged with token counts, cost (8-decimal USD precision), latency, and custom tags for per-team or per-feature attribution.
Key features:
- Budget alerts via email, Slack, or Teams at configurable thresholds
- Hard spending caps that block requests when monthly budget is exceeded
- Analytics dashboard with spend-by-model, daily trends, and cost optimization reports
- BYOK (Bring Your Own Keys) with AES-256 encryption
- Rate limiting per API key
- Works with any language or HTTP client (PHP, Python, Node.js, Go, Ruby)
