We have a Datagma node ready for N8N, that allows you to consume the Find Email endpoint or Enrich endpoint.
This node is a community node, which means it's not a node created by the N8N team, but by the Datagma team.
You can access it following this instruction :
Go to settings
Then Community nodes
Type: n8n-nodes-datagma
You can now use Datagma on N8N
Keep in made that this solution is only available for the self-hosted version of N8N.
In the other cases, you need to create an HTTP node on N8N
