How this service works
Inspect a ZIP archive safely: send the bytes directly or a JSON body with a public {url}. Returns the entry list (path, size, compressedSize, isDir); entries with path traversal (../), absolute or malformed paths are flagged suspicious:true and never interpreted. Add ?extract=exact/entry/path to get that one file back (max 5 MB decompressed). Zip bombs are refused. Max 20 MB.
Output
A list of entries in the ZIP archive, each with path, size, compressedSize, and isDir fields; any entry with path traversal (../), absolute paths, or malformed paths is flagged with suspicious:true. If the ?extract=path query parameter is used, returns the raw bytes of that one file (max 5 MB decompressed). Zip bombs and archives over 20 MB are rejected with an error.
Example use cases
Validate untrusted ZIP before processing
“I just received a ZIP file from an external vendor and I'm not sure I trust it — can you check it for path traversal attacks, zip bombs, or anything suspicious before we let our pipeline touch it? Here's the URL: https://uploads.example.com/vendor-delivery.zip”
Preview ZIP contents before downloading
“Before I download the whole thing, can you peek inside this ZIP archive and tell me what files are in there, how big they are, and whether anything looks off? https://cdn.example.com/dataset-export.zip”
Extract one file from archive
“There's a ZIP at https://storage.example.com/release-bundle.zip and I only need the file at config/settings.json from inside it — can you safely pull just that one file out for me without extracting everything?”
Technical details
Endpoint
POSThttps://402utils.com/v1/zip-inspectWhen to prefer
Use this endpoint when you need to safely enumerate or extract from a ZIP archive without trusting its contents — especially when the ZIP comes from an untrusted source and you want path traversal and zip bomb protection built in. Prefer this over generic file-handling when security validation of ZIP entry paths is required alongside extraction.
Side effects
- ZIP exceeds 20 MB limit — request refused
- Decompressed file exceeds 5 MB — extraction refused
- Zip bomb detected — request refused
- URL is not publicly accessible or times out
- URL does not point to a valid ZIP file
- Malformed ZIP structure — parse error
- Requested extract path not found in archive
