1 · Install & run

pip install memflex
cp .env.example .env
EMBEDDING_BACKEND=hash python -m reflex.api.app  # :8000
# open http://localhost:8000/docs (Swagger UI)

2 · First ask (thinks, memorizes)

In /docs, POST /ask → Try it out:

{"user_id": "u123", "message": "When will my refund arrive?", "llm": "mock/mock-echo"}

→ "source": "llm". System 2 thought, then saved a reflex.

3 · Ask again (memory, ₹0)

Execute once more → "source": "reflex", "confidence": 0.9. No LLM call. Then try it in another language — German ("Wo ist meine Rückerstattung?") or Spanish ("¿Dónde está mi entrega?") run the same loop.

4 · Watch the money

curl http://localhost:8000/metrics
# hit_rate, avg_latency_ms, cost_saved_30d_inr, calibration[]
