I have some PromQL queries that I want to execute via HTTP request using the APIs given by Prometheus.

For example, having this query:

sum by (name) (container_memory_working_set_bytes{namespace="verification",pod=~".+",container!="POD",container=~".+"})

how can I put in the HTTP requests?

I tried writing like this:

curl -g 'http://localhost:9090/api/v1/query?sum by (name) (container_memory_working_set_bytes{namespace="verification",pod=~".+",container!="POD",container=~".+"})' | jq

but I received "curl: (56) Recv failure: Connection reset by peer"

Could enyone help me to understand how set te requests with the query (and if I'm wrong in writing the curl request)? Thank you all!
