APIs are the backbone of your app — when they fail, everything breaks. We fix 500 errors, CORS issues, timeout problems, and broken integrations. Working code via GitHub PR within 48 hours.
These are the API errors we fix most often.
We find the actual cause — not just patch the error message.
API handlers catch errors silently or throw them without proper HTTP status codes — Next.js returns 500 for any unhandled error.
Handlers must export named functions (GET, POST, etc.) — missing exports cause silent 404 responses.
OPTIONS requests are not handled, causing browsers to block actual API requests with CORS errors.
Request body format (JSON vs FormData vs URLSearchParams) does not match how the handler parses it.
API returns data in one format but sets a different Content-Type header, causing client-side parsing failures.
Four steps to working APIs.
Link your GitHub repository. We support public and private repos — you control access.
We trace the request through the full API lifecycle — from handler entry to response exit.
