Claude Code setup guide - Mint Starter Kit

Claude Code uses the Anthropic Messages protocol. To use it with the powertokens platform, point Claude Code at https://api.powertokens.ai and choose a text model available through the Anthropic Messages path. The recommended platform default is glm-5.2; the recommended MiniMax coding-agent path is MiniMax-M3. If you need to choose the endpoint first, see Text model protocols and endpoints.

Available models

Use the following model IDs with Claude Code. For coding-agent workflows, prefer glm-5.2 or MiniMax-M3.

Upstream provider	Model ID	Recommended use
Zhipu	`glm-4.5-air`	Lightweight coding help
Zhipu	`glm-4.7`	General development tasks
Zhipu	`glm-4.7-flash`	Fast lightweight coding tasks
Zhipu	`glm-5`	Deeper reasoning and edits
Zhipu	`glm-5-turbo`	Faster coding tasks
Zhipu	`glm-5.2`	Heavier reasoning; configure manually if it is not shown in model discovery
MiniMax	`MiniMax-M2.5`	General agentic coding
MiniMax	`MiniMax-M2.5-highspeed`	Latency-sensitive tasks
MiniMax	`MiniMax-M2.7`	General development and longer tasks
MiniMax	`MiniMax-M2.7-highspeed`	Faster long tasks
MiniMax	`MiniMax-M3`	Complex coding-agent work
Alibaba Qwen	`qwen3-coder-plus`	Optional coding model
Alibaba Qwen	`qwen3-max`	Optional general reasoning model
Alibaba Qwen	`qwen3.5-flash`	Optional lightweight model
Alibaba Qwen	`qwen3.6-plus`	Optional balanced model
BytePlus DeepSeek	`deepseek-v3-2-251201`	Optional text model; passed opencode Anthropic-provider tool validation
BytePlus Seed	`seed-1-6-250915`	Optional text model
BytePlus Seed	`seed-1-8-251228`	Optional text model
BytePlus Seed	`seed-2-0-lite-260228`	Optional lightweight model
BytePlus Seed	`seed-2-0-mini-260215`	Optional lightweight model
BytePlus Seed	`seed-2-0-pro-260328`	Optional heavier text model

Prepare your environment

Install or update Claude Code:

npm install -g @anthropic-ai/claude-code
claude --version

Clear old Anthropic environment variables before switching providers:

unset ANTHROPIC_BASE_URL
unset ANTHROPIC_API_KEY
unset ANTHROPIC_AUTH_TOKEN
unset ANTHROPIC_MODEL

Configure Claude Code

Add this to user-level ~/.claude/settings.json or project-level .claude/settings.json:

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.powertokens.ai",
    "ANTHROPIC_AUTH_TOKEN": "YOUR_POWERTOKENS_API_KEY",
    "ANTHROPIC_MODEL": "glm-5.2",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "glm-5-turbo",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "glm-5.2",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "MiniMax-M3",
    "CLAUDE_CODE_SUBAGENT_MODEL": "glm-5.2",
    "CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY": "1"
  }
}

Claude Code should use ANTHROPIC_AUTH_TOKEN so the client sends a bearer token. Do not set both ANTHROPIC_AUTH_TOKEN and ANTHROPIC_API_KEY; Claude Code gives ANTHROPIC_AUTH_TOKEN precedence. If your runtime explicitly requires x-api-key auth, replace ANTHROPIC_AUTH_TOKEN with ANTHROPIC_API_KEY.

Start and verify

Run Claude Code from your project:

claude

Inside the session, check:

/status
/model

If the model picker does not show platform models, set ANTHROPIC_MODEL manually to one of the IDs above. Some discovery flows only show model IDs that begin with claude or anthropic; manual model IDs still work when the gateway accepts them. Verify that Claude Code reads the configuration in non-interactive mode:

claude -p --model glm-5.2 "Reply exactly: ok"

Then verify tool use with a local file:

printf "powertokens-compat-ok\n" > compat.txt
claude -p --model glm-5.2 --tools=Read --allowedTools=Read \
  "Use the Read tool to read compat.txt. Reply exactly with the file contents."
rm compat.txt

You can also verify the same model directly through the platform API.

curl -X POST "https://api.powertokens.ai/v1/messages" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_POWERTOKENS_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  --data '{
    "model": "glm-5.2",
    "max_tokens": 64,
    "messages": [
      {"role": "user", "content": "Reply with ok."}
    ],
    "stream": false
  }'

Model choice

Scenario	Suggested model
Default coding agent	`glm-5.2`
Small edits	`glm-5-turbo`
Complex code review	`glm-5.2` or `MiniMax-M3`
Parallel subagents	`glm-5.2` as main model and `glm-5-turbo` as the lightweight model
MiniMax coding-agent path	`MiniMax-M3`

Not default recommendations

The following models may declare anthropic in model discovery, but current ecosystem-tool validation does not recommend them as Claude Code defaults:

Model	Reason
`seed-1-6-flash-250715`	The upstream provider does not support `/v1/messages`; use an OpenAI-compatible provider
