Recipes

Self-contained end-to-end recipes. Each one is a runnable sequence of nak and curl commands assuming $NSEC (your private key) is set in the environment.

Don’t leak $NSEC to shell history. Either prefix commands with a space (with HISTCONTROL=ignorespace) or unset NSEC after each session.

Stream a test pattern via Shosho Server

End-to-end: create a Nostr identity, get streaming credentials from Shosho Server, go live with an FFmpeg test pattern, post to chat, then end the stream cleanly.

# Step 1: Create identity (skip if user already has one)
NSEC=$(nak key generate)
PUBKEY=$(nak key public $NSEC)
NPUB=$(nak encode npub $PUBKEY)
echo "Created user: $NPUB"
 
# Step 2: Publish relay list (kind 10002)
nak event -k 10002 \
  -t r=wss://relay.damus.io \
  -t r='wss://relay.primal.net;write' \
  --sec $NSEC \
  wss://relay.damus.io wss://relay.primal.net wss://purplepag.es
 
# Step 3: Publish profile (kind 0)
nak event -k 0 \
  --content '{"name":"AI Test Streamer","about":"Test stream from an AI agent","picture":"https://robohash.org/'$PUBKEY'.png"}' \
  --sec $NSEC \
  wss://relay.damus.io wss://relay.primal.net wss://purplepag.es
 
# Step 4: Get Shosho Server account info
AUTH=$(nak event -k 27235 \
  -t u=https://api.shosho.live/api/v1/account \
  -t method=GET \
  --sec $NSEC < /dev/null 2>/dev/null | base64)
ACCOUNT=$(curl -s -H "Authorization: Nostr $AUTH" \
  https://api.shosho.live/api/v1/account)
echo "Account: $ACCOUNT"
 
# Step 5: Accept terms of service (if not already accepted)
AUTH=$(nak event -k 27235 \
  -t u=https://api.shosho.live/api/v1/account \
  -t method=PATCH \
  --sec $NSEC < /dev/null 2>/dev/null | base64)
curl -X PATCH -H "Authorization: Nostr $AUTH" \
  -H "Content-Type: application/json" \
  -d '{"accept_tos": true}' \
  https://api.shosho.live/api/v1/account
 
# Step 6: Set stream metadata (title, summary)
AUTH=$(nak event -k 27235 \
  -t u=https://api.shosho.live/api/v1/event \
  -t method=PATCH \

  -d '{"title": "AI Test Stream", "summary": "Testing live streaming from an AI agent"}' \
  https://api.shosho.live/api/v1/event
 
# Step 7: Extract ingest URL and stream key from the account response
# e.g. INGEST_URL="rtmp://ingest.shosho.live:1935/Basic"  STREAM_KEY="<key>"
INGEST_URL=$(echo "$ACCOUNT" | python3 -c "import sys,json; print(json.load(sys.stdin)['endpoints'][0]['url'])")
STREAM_KEY=$(echo "$ACCOUNT" | python3 -c "import sys,json; print(json.load(sys.stdin)['endpoints'][0]['key'])")
 
# Step 8: Start FFmpeg test pattern in the background
ffmpeg -f lavfi -i testsrc=size=1280x720:rate=30 \
  -f lavfi -i sine=frequency=440:sample_rate=44100 \
  -vcodec libx264 -preset veryfast -b:v 2500k \
  -acodec aac -b:a 128k \
  -f flv "$INGEST_URL/$STREAM_KEY" &

NADDR=$(nak encode naddr -k 30311 -d $D_TAG -a $AUTHOR -r wss://relay.damus.io < /dev/null)
echo "You are live! Watch at: https://shosho.live/live/$NADDR"
 
# Step 11: Post a chat message

# Step 12: Stop FFmpeg

# Step 13: Wait for Shosho Server to publish status: ended
sleep 15

Go live via the Show Chat API

Use this when you already have an HLS playback URL from your own server (or a third-party hosted service) and want Shosho to manage the Nostr live event for you. See Going live → Option C.

# Replace with the HLS URL of your existing stream
HLS_URL="https://your-server.com/stream.m3u8"
D_TAG="my-show-$(date +%s)"
 
# Step 1: Create the show-chat (publishes the kind 30311 with status: live)
AUTH=$(nak event -k 27235 \
  -t u=https://shosho.live/api/show-chat/create \
  -t method=POST \
  --sec $NSEC < /dev/null 2>/dev/null | base64)
RESP=$(curl -s -X POST -H "Authorization: Nostr $AUTH" \
  -H "Content-Type: application/json" \
  -d '{
    "dTag": "'"$D_TAG"'",
    "hlsUrl": "'"$HLS_URL"'",
    "title": "My Live Stream",
    "summary": "Going live via Show Chat",
    "image": "https://robohash.org/'$(nak key public $NSEC)'.png"
  }' \
  https://shosho.live/api/show-chat/create)
NADDR=$(echo "$RESP" | python3 -c "import sys,json; print(json.load(sys.stdin)['naddr'])")
echo "Live at: https://shosho.live/live/$NADDR"
 
# Step 2: Stream is now live. The Shosho backend will poll the HLS URL
# every minute and republish the 30311 every 15 minutes automatically.
 
# Step 3: When you're done, end the stream cleanly
AUTH=$(nak event -k 27235 \
  -t u=https://shosho.live/api/show-chat/update \
  -t method=POST \
  --sec $NSEC < /dev/null 2>/dev/null | base64)

  https://shosho.live/api/show-chat/update
echo "Stream ended."

Post a clip from a video file

Upload a video to nostr.build, then publish a NIP-71 clip event (kind 34236 for short/vertical, 34235 for normal/horizontal).

# Step 1: Upload video to nostr.build
AUTH=$(nak event -k 27235 \

# Extract URL, sha256, mime, dimensions, and thumbnail from the response.
# Adjust to your local jq / python preference.
VIDEO_URL=$(echo "$UPLOAD" | python3 -c "import sys,json; r=json.load(sys.stdin); imeta=next(t for t in r['nip94_event']['tags'] if t[0]=='url'); print(imeta[1])")

# Step 2: Publish clip (kind 34236 = short/vertical, 34235 = normal/horizontal)
CLIP_D="my-clip-$(date +%s)"
PUBKEY=$(nak key public $NSEC)
nak event -k 34236 \
  --content "A clip from my stream — full description goes in content." \

echo "Clip posted: https://shosho.live/clips/$NADDR"

List a product for sale

Upload a product image, then publish a NIP-99 classified listing (kind 30402).

# Step 1: Upload product image to nostr.build
AUTH=$(nak event -k 27235 \
  -t u=https://nostr.build/api/v2/nip96/upload \
  -t method=POST \
  --sec $NSEC < /dev/null 2>/dev/null | base64)
UPLOAD=$(curl -s -X POST \
  -H "Authorization: Nostr $AUTH" \
  -F "file=@product-photo.jpg" \
  https://nostr.build/api/v2/nip96/upload)
IMAGE_URL=$(echo "$UPLOAD" | python3 -c "import sys,json; r=json.load(sys.stdin); imeta=next(t for t in r['nip94_event']['tags'] if t[0]=='url'); print(imeta[1])")
 
# Step 2: Publish product listing
PRODUCT_D="product-$(date +%s)"
PUBKEY=$(nak key public $NSEC)
NPUB=$(nak encode npub $PUBKEY)
 
nak event -k 30402 \
  --content "Full product description in **markdown**. Supports *italic*, [links](https://example.com), and lists." \
  -t d=$PRODUCT_D \
  -t title="My Product" \
  -t 'price=21000;sats' \
  -t summary="Short tagline for the product" \
  -t published_at=$(date +%s) \
  -t location="Worldwide shipping" \
  -t image=$IMAGE_URL \
  -t t=nostr \
  -t status=active \
  --sec $NSEC \
  wss://relay.damus.io wss://relay.primal.net
 
echo "Product listed."
echo "Shop: https://shosho.live/profile/$NPUB?tab=shop"
echo "Product: https://shosho.live/product/$NPUB-$PRODUCT_D"
