More Anthropic use cases
Bring Your Own Anthropic Key
Connect your Anthropic API key and LunoGen uses your account for all Claude calls. You control billing, model access, and rate limits — and gain access to the latest Claude releases as soon as they ship.
Claude Opus for Complex Reasoning
Route your hardest tasks — deep research, multi-step tool use, long planning — to Claude Opus. The agent detects complexity and automatically uses Opus when the prompt needs it.
Prompt Caching for Cost Savings
LunoGen caches your long system prompt, memory context, and knowledge base on Anthropic's side. Repeated calls hit the cache and cost a fraction of normal tokens — often cutting bills by 70% or more.
Messages API with Tool Use
LunoGen uses Anthropic's Messages API with tool use for structured agent actions. Claude decides which tool to call, and the agent executes HTTP requests, sends WhatsApp messages, or writes files in one loop.
Vision Tasks on WhatsApp Images
Send an image to the agent on WhatsApp and it runs Claude vision — reading receipts, describing screenshots, extracting handwritten notes, or checking a product photo for defects.
