Connect your tool to the API

From opening a terminal to sending your first message. Choose your tool and operating system.

This is a PROX setup preview. You can install the tools now. To connect, you’ll need a PROX AI key and a live endpoint for your tool.

01Install the tool
Open Start, search for PowerShell 7, and launch it. At a Read-Host prompt, paste your key and press Enter.
Run each line and wait for the version number. On Windows, use the official installer if WinGet is unavailable.
PowerShell
```
winget install Anthropic.ClaudeCode
claude --version
```
If npm is missing, install Node.js LTS, then close and reopen your terminal.
Installation docs Download Node.js LTS
02Choose the provider and model
A PROX model ID always starts with prox/, for example prox/claude-opus-5.5, so it is not confused with the publisher's own model. Replace MODEL_ID in the examples with the model name from the model table, the part after prox/. Do not type prox/ twice.
Claude Code uses ANTHROPIC_BASE_URL to reach your provider. Keep the example address for PROX and select a model with --model. These commands use a bearer key.
PowerShell
```
$env:ANTHROPIC_BASE_URL = "https://ai.smmpanelsale.com"
$env:ANTHROPIC_AUTH_TOKEN = Read-Host "PROX API key" -MaskInput
claude --model "prox/MODEL_ID"
```

03Send your first message
In Claude Code, enter /status to verify the gateway address. Then send the sample message below.

Hi. Explain what an API is in one sentence. There’s no need to read or edit any files.

If the connection fails

401 / 403: Check that the key is active and has access to the model. Restart the tool in the same terminal where you entered it.
404: Check the model ID (with the prox/ prefix), the /v1 part of the base URL, and the protocol your tool expects.
429: Check your quota or request limit. Wait a moment and try again.
5xx / timeout: Check the portal’s service status and try again later.
