Claude Code

Claude Code is Anthropic's terminal agent. Route it through Hyper using our Anthropic Messages API endpoints.

Prerequisites

A Hyper account with an API key
Claude Code installed

Configuration

Option 1: Settings file (recommended)

Add this to ~/.claude/settings.json. This persists across sessions without needing shell env vars:

json

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://hyper.charm.land",
    "ANTHROPIC_API_KEY": "sk-hyper-xxxxxxxxxxxxxxxxxxxxxxxx",
    "ANTHROPIC_MODEL": "deepseek-v4-pro",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "qwen3.7-max",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "deepseek-v4-flash"
  }
}

The alias variables let you use Claude Code's built-in /model sonnet and /model haiku commands with Hyper models:

Alias	Env Var	Suggested Model
`sonnet`	`ANTHROPIC_DEFAULT_SONNET_MODEL`	A strong mid-tier model for daily coding
`haiku`	`ANTHROPIC_DEFAULT_HAIKU_MODEL`	A fast model for quick tasks and subagents

You can also set CLAUDE_CODE_SUBAGENT_MODEL to route all subagent work to a cheaper model:

json

{
  "env": {
    "CLAUDE_CODE_SUBAGENT_MODEL": "deepseek-v4-flash"
  }
}

Option 2: Environment variables

If you prefer shell config over a settings file:

bash

export ANTHROPIC_BASE_URL="https://hyper.charm.land"
export ANTHROPIC_API_KEY="sk-hyper-xxxxxxxxxxxxxxxxxxxxxxxx"
export ANTHROPIC_MODEL="deepseek-v4-pro"
export ANTHROPIC_DEFAULT_SONNET_MODEL="qwen3.7-max"
export ANTHROPIC_DEFAULT_HAIKU_MODEL="deepseek-v4-flash"

Running Claude Code

With configuration in place, start Claude Code normally:

bash

claude

Use /model to switch between your configured aliases mid-session. All model names map to the Hyper catalog.
