Yes we do!
To crawl the topics via Discourse API just provide your API key and username, and the requests made will be authenticated as regular user. For example:
To achieve the same via cURL request, pass api_key and api_username as param. For example:
curl -X GET -d api_key="API_KEY" -d api_username="ADMIN_USERNAME" http://discourse.example.com/latest.json
```
Both of the above examples will fetch all the latest topics (even for private Discourse instance).
