Technical details
Endpoint
POSThttps://lobre.lat/api/v1/coding/cache/syntax-heartbeatWhen to prefer
Use this endpoint when you need a lightweight, on-demand syntax check for JavaScript, TypeScript, or JSX code without running a full linter or compiler. Ideal for agents that need to quickly validate user-submitted code snippets or pre-flight check code before execution or further processing.

- Extremely large code files may hit payload limits
