# Quickstart

Welcome to the APRO AI Oracle API. We provide a wide range of oracle data, including market data and news. All data undergoes distributed consensus to ensure its trustworthiness and immutability.

## Getting Started

1. **Contact Our BD Team** Apply for API access through our Business Development team. We offer basic plans and higher-rate paid plans.
2. **Test with Your API Key** Use the code samples below to test your key and make API requests.
3. **Integrate with Your Application** After verifying your API key, explore this documentation to start building.

> ⚠️ **Important**: Always route your API calls through your own backend server to protect your API key.

### 🔐 API Authentication & Credit System

* **V1**: No API key required.
* **V2**: Requires `X-API-KEY` and `X-API-SECRET` headers.

All API requests are subject to credit-based rate limiting. Each endpoint will indicate how many credits it consumes.

## Base URL

**TestNet**: <https://api-ai-oracle-test.apro.com\\>
**MainNet**：<https://api-ai-oracle.apro.com>

## **Making an API Request**

To call the API, direct the request to the specified API method and attach the required parameters. For a complete reference of available API methods, see the [APRO AI Oracle API v1](/ai-oracle/getting-started/quickstart/apro-ai-oracle-api-v1.md) in the sidebar.&#x20;

### **Example Using Axios in TypeScript**

**V1: Fetch Supported Currencies**

```typescript
import axios from 'axios'

function API() {
    async function apiFunction() {
        const res = await axios
            // "Call URL", {configuration headers}
            .get("https://api-ai-oracle-test.apro.com/v1/ticker/currencies/list?size=50&page=1")
            .catch((error) => console.log(error))
        console.log(res)
    }
}
```

**V2: Fetch Supported Currencies (with API key)**

```javascript
import axios from 'axios'

function API() {
    async function apiFunction() {
        const res = await axios
            // "Call url", {configuration headers}
            .get("https://api-ai-oracle.apro.com/v2/ticker/currencies/list?size=50&page=1", 
                {
                    headers: {
                        'X-API-KEY': 'YOUR_API_KEY',
                        'X-API-SECRET': 'YOUR_API_SECRET',
                        }
                }
            )
            .catch((error) => console.log(error))
        console.log(res)
    }
}
```

### **Evaluating API Responses**

Our API responses follow a standard response structure. Responses are returned in JSON format.
