Antivirus API
Antivirus REST API to scan files and detect viruses, trojans, and other malware in both uploaded and external files.
1 Upload your file
Firstly, your file must be uploaded or accessible to Bytescale:
Use the Bytescale Dashboard to upload a file manually.
Use the Upload Widget, Bytescale SDKs or Bytescale API to upload a file programmatically.
Use our external storage options to process external files.
2 Build your file URL
To build a URL to scan a file for viruses:
Get the raw URL for your file:
https://upcdn.io/W142hJk/raw/example.jpg
Replace "raw" with "antivirus":
https://upcdn.io/W142hJk/antivirus/example.jpg
3 Get the antivirus report
The Antivirus API initially returns a status of "Pending":
https://upcdn.io/W142hJk/antivirus/example.jpg{ "jobUrl": "https://api.bytescale.com/v2/accounts/W142hJk/jobs/AntivirusJob/01HGB4G3R466T9EBDVK015JMXS", "jobDocs": "https://www.bytescale.com/docs/job-api/GetJob", "jobId": "01HGB4G3R466T9EBDVK015JMXS", "jobType": "AntivirusJob", "accountId": "W142hJk", "created": 1700179632246, "lastUpdated": 1700179633360, "status": "Pending", "summary": {}}After a few seconds, the status progresses to "Succeeded" and your antivirus report will appear in the summary.result field.

Example #3: Skipped file
{ "jobUrl": "https://api.bytescale.com/v2/accounts/W142hJk/jobs/AntivirusJob/01HGB4G3R466T9EBDVK015JMXS", "jobDocs": "https://www.bytescale.com/docs/job-api/GetJob", "jobId": "01HGB4G3R466T9EBDVK015JMXS", "jobType": "AntivirusJob", "accountId": "W142hJk", "created": 1700179632246, "lastUpdated": 1700179633360, "status": "Succeeded", "summary": { "result": { "files": [ { "filePath": "/example.jpg", "viruses": [], "skippedReason": "FileTooLarge", "status": "Skipped" } ], "database": { "databaseAge": "10 minutes", "databaseLastChecked": 1700179032353, "databaseLastUpdated": 1700124000000, "knownViruses": 8694209 }, "scanStartTime": 1700179632353, "scanEndTime": 1700179633348 } }}See AntivirusReport for more details.
Files may be skipped for the following reasons:
FileTooLarge: File size exceeds the 2GB limit for virus scans.
ContentTooLarge: Uncompressed content exceeds the 4GB limit for virus scans. (This applies to any file format that uses compression.)
Timeout: Scan duration exceeds the 240-second limit.
ArchiveFileCountTooHigh: File is an archive (e.g. ZIP) that contains over 10,000 files.
ArchiveRecursionTooHigh: File is an archive (e.g. ZIP) that contains other archives (e.g. other ZIPs) over 10 levels deep.
Other: File was skipped due to other internal limits. (For more information on this status code, please contact support.)
Security recommendation: You should always enforce a file size limit on your uploads (< 2GB). After your files have finished uploading, you should check each file's status using the Antivirus API. When status != "Healthy" you should discard the file. You can optionally delete the file and inform the user.
