# Origin Errors API Reference

> Retrieve origin error logs for your pull zones via HTTP.

The Origin Errors API provides visibility into failed origin requests. Query error logs by pull zone and date to identify DNS failures, timeouts, and other origin issues.

## Base URL

```
https://cdn-origin-logging.bunny.net
```

## Authentication

Authenticate using the `AccessKey` header with your account API key:

```bash theme={null}
curl --request GET \
  --url https://cdn-origin-logging.bunny.net/{pullZoneId}/{dateTime} \
  --header 'AccessKey: YOUR_API_KEY'
```

<Note>
  Find your API key in the [account
  settings](https://dash.bunny.net/account/settings) under **API Keys**.
