Upload files to your sandbox execution. Files are written to the working directory and can be accessed directly by filename.

File Object Schema

Example Request

{
  "language": "python",
  "code": "print(open('data.csv').read())",
  "input_files": [
    {

Limits

• Maximum files: 10 files per execution
• Maximum total size: 10MB (decoded)
• Maximum single file: 5MB (decoded)
• Filename length: 256 characters max

File Access

Files are placed in the working directory. Access them directly:

• Python: open('data.csv')
• Node.js: fs.readFileSync('data.csv')
• Ruby: File.read('data.csv')
• Go: os.ReadFile("data.csv")

Security

• Files are isolated per execution
• Filenames cannot contain path separators (no / or ..)
• Files are deleted after execution completes
