## API Services

Each endpoint in the API has a corresponding method in the SDK. Here are some examples:

| API Route                     | SDK Method                                   | Description                                        |
| ----------------------------- | -------------------------------------------- | -------------------------------------------------- |
| `/ai/v1/chat/completions`     | `client.ai.v1.chat.generateCompletion()`     | AI chat completion using Messari's standard format |
| `/ai/openai/chat/completions` | `client.ai.openai.chat.generateCompletion()` | AI chat completion in OpenAI-compatible format     |
| `/api/v1/assets`              | `client.signal.v0.assets.list()`             | List all tracked assets                            |
| `/api/v1/assets/{assetId}`    | `client.signal.v0.assets.retrieve()`         | Get details for a specific asset                   |

## Example Usage

### AI Chat Completion

```typescript theme={null}
import MessariSDK from "@messari/sdk-ts";

// Initialize the client
const client = new MessariSDK({
  apiKey: process.env["MESSARI_SDK_API_KEY"],
});

// Use the AI service
const response = await client.ai.openai.chat.generateCompletion({
  messages: [
    {
      role: "user",
      content: "What companies have both paradigm and a16z on their cap table?",
      MultiContent: [{}],
    },
  ],
  inlineCitations: true,
});
console.log(response.choices[0].message.content);
```
