Max Mayfield 167d3be2e4 Implement all remaining P1 Rust TODOs: Slack alerts, Resend emails, pricing refresh, AES-256-GCM key encryption
- anomaly.rs: Slack Block Kit webhook + Resend email on 3x cost spike
- digest.rs: Weekly HTML digest email via Resend with model usage + savings tables
- main.rs: Daily pricing refresh with hardcoded table (OpenAI/Anthropic/Google models)
- handler.rs: AES-256-GCM encryption for provider API keys (nonce || ciphertext storage)

dd0c/route — LLM Cost Router & Optimization Dashboard

Drop-in OpenAI-compatible proxy that routes AI requests to the cheapest capable model.

Quick Start

# Start local infra
docker compose up -d

# Run the proxy
OPENAI_API_KEY=sk-your-key cargo run --bin dd0c-proxy

# Test it
curl http://localhost:8080/v1/chat/completions \
  -H "Authorization: Bearer your-dd0c-key" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-4o","messages":[{"role":"user","content":"Hello"}]}'

Architecture

  • Proxy Engine (Rust/Axum) — <5ms overhead, SSE streaming, async telemetry
  • Router Brain — Complexity classification, cost-based routing, fallback chains
  • Dashboard API — REST API for config, analytics, team management
  • TimescaleDB — Time-series telemetry with continuous aggregates
  • PostgreSQL — Config, auth, routing rules
  • Redis — API key cache, rate limiting
