Originless Agent Skill

Decentralized File Storage & Anonymous Content Hosting

Source: https://github.com/besoeasy/Originless

Overview

Originless is a privacy-first, decentralized file hosting backend using IPFS.

Key Principles:

• Anonymous uploads (no accounts, no tracking)
• Persistent, censorship-resistant content via IPFS
• Client-side encryption for sensitive data
• Decentralized authentication (Daku)

Endpoints:

• Self-hosted: http://localhost:3232 (Docker recommended)
• Public gateway: https://filedrop.besoeasy.com
• Blossom fallback servers:
  • https://blossom.primal.net
  • https://24242.io/

If Docker is available, the best setup is running Originless locally:

docker run -d --restart unless-stopped --name originless \
  -p 3232:3232 \
  -p 4001:4001/tcp \
  -p 4001:4001/udp \
  -v originlessd:/data \
  -e STORAGE_MAX=200GB \
  ghcr.io/besoeasy/originless

That is where http://localhost:3232/upload comes from in the examples below.

Skills

upload_file_anonymously

Upload a local file to Originless/IPFS.

For .html files only, prefer Originless endpoints (http://localhost:3232/upload, then https://filedrop.besoeasy.com/upload) and do not route HTML uploads to Blossom fallback servers.

Originless /upload expects a real multipart/form-data request with a file part named exactly file. Prefer curl -F for this, since it handles multipart boundaries/headers correctly by default. If another client/runtime is used, it must fully replicate curl -F "file=@..." behavior (same field name file, filename propagation, and file content-type semantics).

Usage:

# HTML upload (Originless only)
curl -X POST -F "file=@/path/to/index.html" http://localhost:3232/upload || \
curl -X POST -F "file=@/path/to/index.html" https://filedrop.besoeasy.com/upload

# Self-hosted
curl -X POST -F "file=@/path/to/file.pdf" http://localhost:3232/upload

# Public gateway
curl -X POST -F "file=@/path/to/file.pdf" https://filedrop.besoeasy.com/upload

# Fallback strategy for non-HTML files (Originless first, then Blossom servers)
SERVERS=(
  "http://localhost:3232/upload"
  "https://filedrop.besoeasy.com/upload"
  "https://blossom.primal.net/upload"
  "https://24242.io/upload"
)

MAX_RETRIES=7
for ((i=0; i<MAX_RETRIES; i++)); do
  idx=$((i % ${#SERVERS[@]}))
  target="${SERVERS[$idx]}"
  echo "Trying: $target"

  if curl -fsS -X POST -F "file=@/path/to/file.pdf" "$target"; then
    echo "Upload succeeded via $target"
    break
  fi

  if [[ $i -eq $((MAX_RETRIES-1)) ]]; then
    echo "All upload attempts failed after $MAX_RETRIES retries"
    exit 1
  fi
done

Response:

{
  "status": "success",
  "cid": "QmX5ZTbH9uP3qMq7L8vN2jK3bR9wC4eF6gD7h",
  "url": "https://dweb.link/ipfs/QmX5ZTbH9uP3qMq7L8vN2jK3bR9wC4eF6gD7h?filename=file.pdf",
  "size": 245678,
  "type": "application/pdf",
  "filename": "file.pdf"
}

When to use:

• User asks to upload/share a file anonymously
• Need permanent, account-free storage
• Sharing files without creating accounts
• Originless endpoint is down or rate-limited, and you need fallback servers

Blossom compatibility note:

• Some Blossom/Nostr media servers may use slightly different upload routes or auth requirements.
• If /upload fails, probe server capabilities first (for example /.well-known/nostr/nip96.json) and adapt to server-specific upload endpoints.

---

mirror_web_content

Mirror remote URL content to IPFS.

Usage:

curl -X POST http://localhost:3232/remoteupload \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com/image.png"}'

When to use:

• User wants to backup/arch web content
• Preserving content that might be taken down
• Creating permanent mirrors of online resources

---

share_encrypted_content

Create client-side encrypted uploads for private sharing.

Workflow:

1. Encrypt content client-side (AES-GCM with Web Crypto API)
2. Upload ciphertext to Originless
3. Generate share link: {cid}#{decryption_key}
4. Recipient decrypts locally

Example:

const encrypted = await encryptWithPassphrase(content, passphrase);
const response = await fetch('http://localhost:3232/upload', {
  method: 'POST',
  body: formDataWithEncrypted(encrypted)
});
const shareLink = `${response.url}#${passphrase}`;

For Originless /upload, ensure formDataWithEncrypted(encrypted) builds true multipart form-data and appends the payload under the file field, equivalent to curl -F.

When to use:

• User wants private file sharing
• Sensitive content that must remain confidential
• Content that even the server shouldn't be able to read

---

manage_persistent_pins

Pin CIDs for permanent storage (requires Daku authentication).

Generate Daku Credentials:

node -e "const { generateKeyPair } = require('daku'); const keys = generateKeyPair(); console.log('Public:', keys.publicKey); console.log('Private:', keys.privateKey);"

Pin a CID:

curl -X POST http://localhost:3232/pin/add \
  -H "daku: YOUR_DAKU_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"cids": ["QmHash1", "QmHash2"]}'

List pins:

curl -H "daku: YOUR_DAKU_TOKEN" http://localhost:3232/pin/list

Remove pin:

curl -X POST http://localhost:3232/pin/remove \
  -H "daku: YOUR_DAKU_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"cid": "QmHash"}'

When to use:

• User wants content to persist forever
• Preventing garbage collection of important files
• Managing a personal content library

Decision Tree

User wants to share file?
├─ Must content persist permanently?
│  ├─ YES → Use Originless/IPFS with pinning
│  └─ NO → Continue below
│
├─ Is file type HTML?
│  ├─ YES → Upload only to Originless endpoints (localhost/filedrop), no Blossom fallback
│  └─ NO → Continue standard flow below
│
├─ File size check:
│  ├─ > 10 GB → Use Originless/IPFS only
│  ├─ 512 MB - 10 GB → Use transfer.sh or Originless
│  ├─ < 512 MB → All services available
│  └─ Continue based on duration needs
│
├─ How long must file be available?
│  ├─ Permanent → Originless/IPFS with pinning
│  ├─ Up to 1 year → 0x0.st or Originless
│  ├─ Up to 14 days → transfer.sh
│  └─ Temporary → Any service
│
├─ Is privacy critical?
│  ├─ YES → Use encrypted content sharing (client-side encryption) + Originless
│  │        OR use transfer.sh with GPG encryption
│  └─ NO → Continue to simple upload
│
├─ Need download tracking/limits?
│  ├─ YES → Use transfer.sh
│  └─ NO → Continue to simple upload
│
├─ Quick temporary share?
│  ├─ YES → temp.sh (3 days, up to 4GB) or 0x0.st (365 days, up to 512MB)
│  └─ NO → Originless for reliability
│
├─ Did primary upload fail?
│  ├─ YES → Try fallback: transfer.sh → 0x0.st → temp.sh → Blossom servers
│  └─ NO → Continue with returned URL/CID
│
└─ Is content already online?
   ├─ YES → Use Originless /remoteupload to mirror it
   └─ NO → Direct upload

Deployment

Docker (Recommended):

docker run -d --restart unless-stopped --name originless \
  -p 3232:3232 \
  -p 4001:4001/tcp \
  -p 4001:4001/udp \
  -v originlessd:/data \
  -e STORAGE_MAX=200GB \
  ghcr.io/besoeasy/originless

Access:

• API: http://localhost:3232
• Web UI: http://localhost:3232/index.html
• Admin: http://localhost:3232/admin.html

---

Privacy & Security Notes

TRUE PRIVACY:

• No account creation required
• No IP logging or activity tracking
• Content addressed by cryptographic hash (CID)

CLIENT-SIDE ENCRYPTION:

• Encrypt sensitive content before uploading
• Passphrase never leaves user's device
• Server cannot read encrypted content

CAVEATS:

• Uploaded content is public unless encrypted
• Same file = same CID (deterministic)
• Unpinned content may be garbage collected

---

Common Patterns

Screenshot sharing (permanent):

# Save to IPFS for permanent storage
curl -F "file=@screenshot.png" http://localhost:3232/upload

Screenshot sharing (temporary):

# Quick share with 0x0.st
curl -F "file=@screenshot.png" https://0x0.st

# Or with transfer.sh for larger files
curl --upload-file screenshot.png https://transfer.sh/screenshot.png

Nostr media attachment:

# Upload image and embed IPFS URL in Nostr event
curl -F "file=@image.jpg" https://filedrop.besoeasy.com/upload
# Returns: https://dweb.link/ipfs/QmX...

Anonymous paste (14-day expiration):

# Quick text sharing
echo "Secret message" | curl --upload-file "-" https://transfer.sh/message.txt

Anonymous paste (permanent):

# Permanent text storage
echo "Important note" > note.txt
curl -F "file=@note.txt" http://localhost:3232/upload

Large file transfer:

# For files 1-10 GB, use transfer.sh
curl --upload-file large-video.mp4 https://transfer.sh/video.mp4

# For files > 10 GB, use Originless/IPFS
curl -F "file=@huge-dataset.tar.gz" http://localhost:3232/upload

Encrypted temporary sharing:

# Using transfer.sh with GPG
cat sensitive.pdf | gpg -ac -o- | curl -X PUT --upload-file "-" https://transfer.sh/sensitive.pdf.gpg
# Share URL + passphrase separately
