API

The agent's setup is adjustable using direct API invocations, facilitating interactive information retrieval and interaction.

Agent API can be reached at https://<<host_name>>:<<port_number>> host_name: Refers to the host where the agent is installed (or localhost if used locally). port_number: By default, the agent listens on port 8282, which can be updated as needed

Examples are demonstrated using localhost as the host name and the default port number 8282.

Certain operations necessitate a header token for transmission to the agent. This token aligns with the agent's license key and the platform it operates on.

// example
export TOKEN=<<datasentinel_token>> 
curl -k --header "api-token: $TOKEN" --request PUT   https://localhost:8282/api/agent/stop'
