# Welcome to ApiSmart

Build with AI models for **text, image, and video** through one unified API platform.

ApiSmart gives developers a consistent way to access supported AI models, manage API credentials, monitor usage, and integrate AI capabilities into applications.

{% hint style="info" %}
**ApiSmart API**

Base URL: `https://gw.apismart.ai/v1`

Authentication: `Authorization: Bearer <your-api-key>`

### 🧩 Find the Right Model

Each API request uses a `model` ID to specify the model you want to call.

To retrieve the latest model list:

```bash
curl https://gw.apismart.ai/v1/models \
  -H "Authorization: Bearer <your-api-key>"
```

Use the returned `data[].id` value as the `model` parameter in supported API requests.

**Model IDs must match exactly.**

Pay attention to periods (`.`), hyphens (`-`), and version numbers when copying a model ID.

For model availability, model IDs, and pricing information, see [**Models and Model IDs**](/models-and-pricing/models-and-model-ids.md) and [**Model Pricing and Billing**](/models-and-pricing/model-pricing-and-billing.md).

### 🔄 Understand Response Modes

Different ApiSmart APIs use different response patterns.

| API              | Response Mode            |
| ---------------- | ------------------------ |
| Chat Completions | Standard or streaming    |
| Image Generation | Synchronous or streaming |
| Video Generation | Asynchronous task        |

For implementation details, see **Response Modes**:

* Standard Responses
* Streaming Text Responses
* Streaming Image Responses
* Asynchronous Video Tasks
