Blank Files Gateway

Use blankfiles.com as a binary test-file gateway: discover formats, filter by type/category, and return direct download URLs from the public API.

Use this skill when the user needs real, downloadable blank binary files for upload testing.

Primary API:

• https://blankfiles.com/api/v1/status
• https://blankfiles.com/api/v1/files
• https://blankfiles.com/api/v1/files/{type}
• https://blankfiles.com/api/v1/files/{category}/{type}

Behavior

1. Prefer the API endpoints above to discover current formats.
2. Return direct file URLs from the API response (files[].url) whenever possible.
3. If a format is not found, suggest close alternatives from the same category.
4. Keep responses concise and practical: format, category, URL, and one-line use case.

Guardrails

• Treat this as a read-only gateway. Do not ask users to run shell scripts or installers.
• Do not fabricate file formats or URLs.
• Always verify availability via API before claiming a format exists.
• Use exact API route shapes (/api/v1/...), not deprecated routes.

Quick Recipes

Find all available formats

Use:

• GET /api/v1/files

Return:

• Total count
• Top relevant matches for user intent
• Direct links

Get one format by type

Use:

• GET /api/v1/files/{type}

Return:

• Matching files with direct URLs
• If none, propose neighboring types in same domain

Get exact category + type

Use:

• GET /api/v1/files/{category}/{type}

Return:

• One direct URL when available
• 404-safe fallback suggestions when missing

Output Template

• format: <type>
• category: <category>
• download_url: <url>
• notes: <short testing context>
