# Removed endpoints

These endpoints were removed from the K-AI Instance API on **2026-04-13**. Their replacements live on the K-AI Retrieval API (exposed via [K-AI MCP](/knowledge-ai/k-ai-mcp/mcp.md)).

## `/search`

**Removed.** Server-side answer composition is no longer offered on the K-AI Instance API.

→ **Replacement:** [K-AI MCP — Retrieval tools (`semantic_nodes_search`)](/knowledge-ai/k-ai-mcp/retrieval-tools.md). The new tool returns raw semantic nodes; the host LLM (over MCP) composes the final answer client-side.

## `/conversation`

**Removed.** K-AI no longer maintains chatbot state server-side.

→ **Replacement:** conversation state is handled on the MCP client side (Claude Desktop, Cursor, Le Chat, ...). The host LLM maintains the history. See [What is MCP](/knowledge-ai/k-ai-mcp/what-is-mcp.md) for context.
