Show HN: Emote – A reaction API for AI agents

Emote launched a reaction API that lets AI agents return a single emoji or "none" from a POST request to https://useemote.com/v1/react, with the reaction delivered while the main model's reply is still generating. The service accepts a message, an agent personality description, and a list of candidate reactions, and returns an emoji, a custom ID, or "none" without tool calls or generated text.
