- URL has never been archived — returns zero count and no snapshot links
- Malformed or missing URL parameter — returns 400-level error
- Wayback Machine API unavailable or rate-limited — returns upstream error or timeout
- URL scheme not supported (e.g. non-HTTP) — may return empty or error response
