OpenClaw Optimization & Cost Savings Tutorial - Save 97% on Cost

A step-by-step walkthrough for reducing OpenClaw API costs by up to 97%. Covers setting up OpenClaw on a VPS using Hostinger with Docker, configuring model routing to use cheaper models (Haiku by default, escalating to Sonnet or Opus as needed), adding fallback providers to handle rate limits, enabling prompt caching for large models, setting up session initialization limits to reduce context bloat, routing heartbeat tasks to a free local Ollama/Llama 3.2 instance, adding context pruning, and running token audits via built-in gateway commands and custom prompts.
