About Stainless
Through Operate As, your agent, n8n workflow or code works in Stainless with your client's own access. Your client pastes their API key from Stainless once. We store it encrypted, so it never sits in an email or a shared doc. Your agent reaches any endpoint of Stainless's API through the request tool, with the client's access attached.
