# Anthropic

> Route Anthropic model calls through Keywords AI Gateway and track requests.

<Note> This section is for **Keywords AI LLM gateway** users.</Note>

Use Keywords AI Gateway to call Anthropic models while keeping unified observability (logs, cost, latency, and reliability metrics) in Keywords AI.

## Prerequisites

* A **Keywords AI API key**
* An **Anthropic API key** (BYOK)

<CardGroup cols={1}>
  <Card title="Get Anthropic API key" icon="key" href="https://console.anthropic.com/">
    Retrieve your API key from the Anthropic Console to begin integration.

## Configuration

There are 2 ways to add your Anthropic credentials to your requests:

### Via UI (Global)

<Steps>
  <Step title="Navigate to Providers">
    Go to the [Providers page](https://platform.keywordsai.co/platform/api/providers). This page allows you to manage credentials for over 20+ supported providers.

      <img src="https://keywordsai-static.s3.us-east-1.amazonaws.com/docs/settings/providers.jpg" alt="Keywords AI Providers Page" />
    </Frame>
  </Step>

  <Step title="Add your Anthropic API Key">
    Select Anthropic and paste your API key.

    </Frame>
  </Step>
</Steps>

### Via code (Per-Request)

You can pass credentials dynamically in the request body. This is useful if you need to use your users' own API keys (BYOK).

Add the `customer_credentials` parameter to your [Gateway request](/api-endpoints/develop/gateway/chat-completions):

```json theme={"system"}
{
  // Rest of the request body
  "customer_credentials": {
    "anthropic": {
      "api_key": "YOUR_ANTHROPIC_API_KEY"
    }
  }
}
```

## Override credentials for a particular model (Optional)

One-off credential overrides. Instead of using what is uploaded for each provider, this targets credentials for individual models.

```json theme={"system"}
{
  // Rest of the request body
  "customer_credentials": {
    "anthropic": {
      "api_key": "YOUR_ANTHROPIC_API_KEY"
    }
  },
  "credential_override": {
    "claude-3-5-sonnet-20240620": {
      "api_key": "ANOTHER_ANTHROPIC_API_KEY"
    }
  }
}
```

## Log Anthropic requests

Monitor your Anthropic Claude API calls by logging requests and responses asynchronously. Track metrics like cost, duration, and performance for all Claude models including Claude 3.5 Sonnet, Claude 3 Opus, and more.

```python Anthropic Python SDK theme={"system"}
import requests

url = "https://api.keywordsai.co/api/request-logs/create/"
payload = {
    "model": "claude-3-5-sonnet-20240620",
    "prompt_messages": [
        {
            "role": "user",
            "content": "What's the weather like today?"
        }
    ],
    "completion_message": {
        "role": "assistant",
        "content": "I don't have access to real-time weather data, but I can help you find weather information."
    },
    "cost": 0.00042,
    "generation_time": 1.8,
    "customer_params": {
        "customer_identifier": "user_456"
    }
}
headers = {
    "Authorization": "Bearer YOUR_KEYWORDS_AI_API_KEY",
    "Content-Type": "application/json"
}

response = requests.post(url, headers=headers, json=payload)
```
