# Authentication

> Learn how to authenticate your API requests

# Authentication

To authenticate your API requests, you need to use bearer tokens. Include your bearer token in the `Authorization` header of each request.

## Example using cURL

Here's an example of how to make an authenticated request using cURL:

```bash theme={null}
curl -H "Authorization: Bearer YOUR_ACCESS_TOKEN" https://api.cdr.fyi/v1/orders
```

### Obtaining an Access Token

To obtain an access token, follow these steps:

1. Log in to your CDR.fyi account.
2. Navigate to your settings page.
3. Click on "API Access".
4. Click "Generate New Token".
5. Copy the generated token.

**NOTE:** You will need access to the CDR.fyi Partner Portal to use the API. If you do not have access, apply [here](https://docs.google.com/forms/d/e/1FAIpQLSePsKG739_XlxinCT5VMlQAte7ezjaHRsXpwPANRLhxu26VCQ/viewform).

**Important:** Keep your access token secure and do not share it publicly. If you suspect your token has been compromised, generate a new one and update your application immediately.

### Token Expiration

Access tokens currently do not expire. However, we recommend periodically rotating your tokens as a best practice for security.

### Rate Limiting

The CDR.fyi API is rate limited to prevent abuse and ensure fair usage. If you exceed the rate limits, you will receive a `429 Too Many Requests` response.

#### Current rate limits:

* 100 requests per minute per token
* 1000 requests per hour per token

If you need higher rate limits for your application, please [contact us](mailto:support@cdr.fyi).
