OAuth Token Disguise

Configure Anthropic OAuth tokens (sk-ant-oat01-*) as working API keys through OpenClaw's env.vars injection.

Core Method

Inject token via environment variable, reference with ${VAR} in provider config:

openclaw config patch '{
  "env": {
    "vars": {
      "ANTHROPIC_API_KEY": "sk-ant-oat01-YOUR_TOKEN"
    }
  },
  "models": {
    "providers": {
      "anthropic-official": {
        "baseUrl": "https://api.anthropic.com",
        "apiKey": "${ANTHROPIC_API_KEY}",
        "api": "anthropic-messages",
        "models": [
          {"id": "claude-sonnet-4-20250514", "name": "Claude Sonnet 4"},
          {"id": "claude-opus-4-6", "name": "Claude Opus 4.6"}
        ]
      }
    }
  },
  "agents": {
    "defaults": {
      "model": {
        "primary": "anthropic-official/claude-sonnet-4-20250514"
      }
    }
  }
}'

Then restart: openclaw gateway restart

Per-Agent Configuration

Apply to a single agent (keep others on proxy):

openclaw config patch '{
  "agents": {
    "list": [{
      "id": "YOUR_AGENT_ID",
      "name": "Agent Name",
      "workspace": "/path/to/workspace",
      "model": {"primary": "anthropic-official/claude-opus-4-6"}
    }]
  }
}'

Verification

Run session_status or openclaw status. Look for:

• 🧠 Model: anthropic-official/* → ✅ success
• custom-proxy/* or fallback notice → ❌ token invalid or auth cooldown

Troubleshooting

Critical: Do not rapidly switch between tokens. OpenClaw tracks auth failures and applies cooldown periods. If stuck in fallback, use session_status with model parameter to force reset:

/model anthropic-official/claude-opus-4-6

Dual Provider Setup

Keep proxy as fallback while using official API:

{
  "env": {"vars": {"ANTHROPIC_API_KEY": "sk-ant-oat01-xxx"}},
  "models": {
    "providers": {
      "custom-proxy": {
        "baseUrl": "https://your-proxy.com/",
        "apiKey": "proxy-key",
        "api": "anthropic-messages",
        "models": [{"id": "claude-sonnet-4-5", "name": "Claude Sonnet 4.5"}]
      },
      "anthropic-official": {
        "baseUrl": "https://api.anthropic.com",
        "apiKey": "${ANTHROPIC_API_KEY}",
        "api": "anthropic-messages",
        "models": [
          {"id": "claude-sonnet-4-20250514", "name": "Claude Sonnet 4"},
          {"id": "claude-opus-4-6", "name": "Claude Opus 4.6"}
        ]
      }
    }
  }
}

Security

• Tokens auto-redacted in config.get output (__OPENCLAW_REDACTED__)
• Direct curl with these tokens fails (only works through OpenClaw)
• Never commit openclaw.json with raw tokens to version control
• Use env.vars (not inline apiKey) to keep tokens in one place
