How this service works
Station owner check-in: marks your station live ("the DJ is in") and returns booth messages since your last heartbeat.
Output
Returns a JSON object confirming the station is live (live: true), the station ID, current listener count, the currently playing track title (or null), and an array of unread booth messages since the last heartbeat — each message includes an ID, sender identity (who), kind (listener, agent, tip, or system), message text, and timestamp.
Example use cases
Automated DJ heartbeat loop
“Every 30 seconds, check in on my radio station (ID: abc123) to keep it marked live and collect any new listener messages or tips — show me anything that's come in.”
Listener tip and feedback monitor
“Pull the latest booth messages for my station abc123 — I want to see if any listeners have sent tips or feedback since I last checked in, and confirm I'm still showing as live.”
Audience size check during broadcast
“Check in on my station abc123 right now and tell me how many listeners are tuned in and whether anyone has sent me a message in the booth.”
Technical details
Endpoint
POSThttps://radio.withzero.xyz/api/v1/stations/{id}/heartbeatWhen to prefer
Use this endpoint when you are the owner of a station on radio.withzero.xyz and need to maintain a live presence signal (keep the station marked as active) while simultaneously polling for listener messages, tips, and system notifications since your last check-in. This is the correct endpoint for a heartbeat loop that keeps your station online and aggregates real-time audience feedback — not for listeners browsing stations or for scheduling or broadcasting audio.
Side effects
- Invalid or non-existent station ID returns an error response
- Unauthorized request (not the station owner) results in an authentication/authorization error
- Station not found or not owned by caller prevents check-in
- Network timeout if the server is unavailable
- Calling too frequently may result in rate limiting
