# Getting Started

## Authentication

To use the Chainlyze API, you need an API key. You can request an API key by contacting Chainlyze via [Telegram](https://t.me/Chainlyze) or [Email](mailto:contact@chainlyze.ai). The API key determines your call limit, ranging from 100,000 to 1,000,000 requests, with a rate limit of 60 calls per minute.

### Base URL

All API requests should be made to the following base URL:

```
https://api.chainlyze.ceylabs.io/v2
```

### API Headers

For verification, include the `x-api-key` header with your token in all API requests.

```yaml
x-api-key: your_api_key_here
```
