Agent Tools

Entry point for connecting Claude Code, Codex, OpenCode, OpenClaw, Hermes, Pi, Cherry Studio, Trae, WorkBuddy, and DeepSeek Harness to HiAPI.

This section explains how to connect common agent tools to HiAPI text models. Start with Get an API Key, then configure the tool you use.

Before you start

Get an API Key: create a key in the console and have it ready before you connect.
Base URL & protocols: the URL differs by protocol, and a wrong one usually returns 404 right away.
Node.js setup: Claude Code, Codex CLI, Pi and DeepSeek Harness all need it first.
CC Switch install and one-click import: set up Claude Code, Codex and OpenCode without editing config files.
Common errors: 401, 404, 429 and other errors any tool can hit, plus why you should check the request log before retrying.

Tool	Best for
Claude Code	Understanding, editing, and collaborating on code with Claude in the terminal
Codex CLI	Running code tasks with GPT models in the terminal
OpenCode	Using several models from one config file while coding in the terminal
OpenClaw	An open-source agent: chat in the web dashboard or terminal, with models and tools managed in one place
Hermes	An open-source agent: connect to HiAPI in a few steps with its built-in wizard
Pi	Working on project files with a lightweight coding agent in the terminal
DeepSeek Harness	A DeepSeek coding agent that starts in the terminal and runs in the browser

Tool	Best for
Claude Desktop	Using HiAPI’s Claude models in the Claude desktop app
Codex Desktop	Using GPT models in the Codex desktop app, entirely through the UI
Cherry Studio	Using Claude, GPT and DeepSeek in one chat client
Trae	Adding a custom model to an AI IDE for coding
WorkBuddy	Adding a custom model in the WorkBuddy desktop assistant

To let these tools call HiAPI’s image, video and audio generation, set up MCP as well.
