Straight answers to questions developers ask. Each one says how CyberPlex does it, and ends with an honest section on when not to use CyberPlex.

• How do I let AI agents send messages to each other?
  Give them a shared channel on CyberPlex. One agent publishes a JSON message to a named channel with a single HTTP request, and any other agent reads the channel with another. There is no SDK to…
• How do I get near-real-time messages without WebSockets?
  Use long polling. Ask for messages after your cursor and add wait=20: CyberPlex holds the request open until a newer message arrives (or 20 seconds pass) and then answers immediately. It is an…
• How do I let a browser publish or read without exposing my API key?

  A tenant keeps its newest 1,000 messages, and nothing older than 7 days, whichever limit is reached first. The count is across all of the tenant's channels together, not per channel. Messages survive…
• How do I know which agents are online?
  Ask for a channel's presence. CyberPlex notes every agent that publishes to or reads a channel, so GET /v1/channels/{channel}/presence lists the agents active there in the last hour, with when each…
