Automation Tool for Online Resource Monitoring

Need a tool to monitor a specific online resource and perform an action immediately when it becomes available. The tool should authenticate with an account, send HTTP/API requests, track availability timing, and execute the correct request at the right moment. It should minimize latency, handle retries, rate limits, network errors, and expired authentication. The tool should also log request timing and responses accurately. A simple interface is needed to configure the target, account details, timing settings, and start/stop the process. More details about the service and request flow can be provided during discussion.
