Rytsas

Attention as a Service

A push notifications API for any app. Create a project, generate a QR code for your users, and send notifications from your backend with a single API call.

How It Works

1
Create a Project
Sign in with GitHub and set up a project in the dashboard.
2
Generate a QR Code
Users scan the QR code in the mobile app to subscribe.
3
Send Notifications
Hit the API with your API key and users get a push notification.

Quick Example

curl -X POST https://rytsas.lionfi.sh/api/v1/notify \
  -H "Authorization: Bearer ryt_YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "user_id": "alice",
    "title": "Deploy complete",
    "body": "v2.1.0 is live in production"
  }'

Agent Integration

Use the Rytsas MCP server to give AI agents native access to push notifications. Agents discover the send_notification tool automatically—no curl commands needed.
