So cool how ecash tokens can function as bearer api tokens like this in routstr: curl -X POST "https://privateprovider.xyz/v1/chat/completions" -H "Authorization: Bearer YOUR_API_KEY" -H "Content-Type: application/json" -d '{ "model": "openai/gpt-4o-mini", "messages": [ {"role":"system","content":"You are Routstr."}, {"role":"user","content":"Ping the node"} ] }'
