Failed API error responses +2 overall pts

GET jimbir.ch/api/posts.json/isagentready-missing-SS4HwZUjZ8tV returned HTTP none; reason: non_json_error.

API error responses
HIGH

Agents call APIs programmatically and cannot recover from an HTML error page. A JSON problem-details body with a machine-readable code and a human-readable message lets them branch on failures instead of guessing.

Return structured JSON error responses for every API path, including unknown ones: HTTP 404 with an application/problem+json (RFC 9457) or application/json body carrying type, title, status and detail. Agents cannot parse HTML error pages. 

{"type": "https://example.com/problems/not-found", "title": "Not found", "status": 404, "detail": "No such resource", "instance": "/api/v1/missing"}
