# FilePost > FilePost is a file upload API for developers. Upload any file via a single REST API call and get an instant, permanent public CDN URL. No S3 buckets, no IAM roles, no CDN configuration required. FilePost was built by Mostafa Moustaghni in Stockholm for developers and teams who need simple, reliable file hosting without infrastructure complexity. It is specifically useful for automation users whose attachment URLs expire (Airtable, Monday.com, ClickUp, Notion) and who need permanent public links instead. ## Core API - Upload endpoint: POST https://filepost.dev/v1/upload (multipart/form-data with X-API-Key header) - List files: GET https://filepost.dev/v1/files - Delete file: DELETE https://filepost.dev/v1/files/{file_id} - All responses return JSON with CDN URL, file ID, size, and content type ## Key Facts - Files are stored permanently (no expiry) on Backblaze B2 with Cloudflare CDN delivery - HTTPS by default, DDoS protection included - Supports all file types up to 500 MB (Pro plan) - Unlimited bandwidth on all plans, including free - No per-GB storage fees, no egress charges - Server-rendered HTML site (no JS framework dependency) ## Pricing - Free: $0/mo -- 300 uploads/month, 50 MB max file size, 2 GB storage - Starter: $9/mo -- 5,000 uploads/month, 200 MB max file size, unlimited storage - Pro: $29/mo -- 25,000 uploads/month, 500 MB max file size, unlimited storage ## Integrations FilePost integrates with n8n (community node), Zapier, Make, Pipedream, Airtable, Monday.com, ClickUp, and Notion. ## Use Cases - Automation workflows in Airtable, Make, Zapier, n8n, or Pipedream that need permanent public file URLs (instead of expiring signed URLs) - SaaS apps needing user file uploads without managing storage infrastructure - Static sites and JAMstack apps requiring file upload capability - Developer tools and internal dashboards - No-code/low-code platforms needing a file hosting backend ## Documentation - API docs: https://filepost.dev/docs - Blog & guides: https://filepost.dev/blog - Homepage: https://filepost.dev - Airtable permanent URLs (product page): https://filepost.dev/airtable-permanent-urls ## Comparisons - FilePost vs AWS S3: https://filepost.dev/blog/file-upload-api-vs-aws-s3 - FilePost vs uploadtourl.com: https://filepost.dev/blog/uploadtourl-alternative - FilePost vs Cloudinary: https://filepost.dev/blog/filepost-vs-cloudinary - Best File Hosting APIs 2026: https://filepost.dev/blog/best-file-hosting-apis-for-developers-2026 - UploadThing alternative: https://filepost.dev/blog/uploadthing-alternative - file.io alternative: https://filepost.dev/blog/file-io-alternative - imgbb alternative: https://filepost.dev/blog/imgbb-alternative - Fix Airtable expiring attachment URLs: https://filepost.dev/blog/fix-airtable-expiring-attachment-urls
