  "summary": "The article discusses the importance of cancellation in API routes and how Jeston, a Node.js framework, facilitates this through RequestContext.signal. This signal can be passed down to application services, ensuring that downstream work stops when the request is no longer active, thus preventing unnecessary resource usage. The article also highlights that Jeston supports AsyncIterable Uint8Array responses for various protocols, enabling streaming endpoints to check the cancellation signal while producing output. This is particularly useful for AI-related applications, where Jeston can provide a clear boundary around agents, inference, evaluation, or training orchestration. Additionally, Jeston offers other features such as bounded request bodies, stable malformed-JSON errors, request deadlines, and automatic OPTIONS behavior, which reduce the number of edge cases that applications need to reimplement.",
