# Authentication

> Authentication requirements and rate limits for the DLN API.

The DLN API is open to everyone with a limited RPS and doesn't require authentication. To make sure we keep delivering a
high-quality service, we've introduced a requirement for commercial integrations to authenticate requests with dedicated API keys.

Please fill in [the Authentication Request form](https://forms.gle/doWLQpr8oemphoaf9) so we can provide you with a dedicated API
key and custom limits.

## Rate Limits

deBridge Liquidity Network API offers generous RPM limits for unauthenticated requests, but authenticated requests with API keys
receive significantly higher limits. This ensures that commercial integrations can operate smoothly without hitting rate limits
while still allowing developers to experiment and build with the API.

| Authentication Status | Rate Limit (RPM) |
| --------------------- | ---------------- |
| Unauthenticated       | 50               |
| Authenticated         | 300              |

More details on how to use your API key and the benefits of authentication can be found in the [API documentation](/dln-details/integration-guidelines/order-creation/creating-order/api-parameters/api-parameters#authentication).
