Hello All,  
I'm trying to run a **search\_explain** API request over my 8.4.2 instance, but I'm getting a 404 error page as a result. I confirmed both EndPoint and the Private key are valid because the request works just by switching to the simple /search API request.

Any idea why the search\_explain is not working?

```auto
curl --location 'https://my-instance.ent.eastus2.azure.elastic-cloud.com/api/as/v1/engines/my-engine/search_explain' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer private-dp3XXXXXXXXXX7uvi7a' \
--data '{
"query": "My Search Criteria"
}'

```

Carlos.

Hi @Carlos_Redondo ,

In 8.4, this API was in Beta, so the URL is `/api/as/v0/` not `/api/as/v1`. Make sure to choose your version when browsing documentation: [Search Explain API (beta) | Elastic App Search Documentation [8.4] | Elastic](https://www.elastic.co/guide/en/app-search/8.4/search-explain.html)

Hope that helps!
