brewpage

Publish content to brewpage.app — free instant hosting for HTML pages, JSON documents, and files. No sign-up required.

Workflow

Step 1: Parse Arguments

Extract from $ARGUMENTS:

--ttl N → TTL in days (default: 15)

Remaining text → content_arg

Step 2: Detect Content Type

Input
Type
API

content_arg is a path AND file exists (test -f)
FILE
POST /api/files (multipart)

content_arg starts with { or [
JSON
POST /api/json

Anything else
HTML
POST /api/html (format=markdown)

For FILE: get file size and MIME type via Bash (file --mime-type -b).
For TEXT/JSON: count characters.

Step 3: Show Pre-Publish Stats

📊 Content:  <type description> · <size> · <api endpoint>
   TTL:      <N> days

Step 4: Ask Namespace

Use AskUserQuestion:

Namespace determines the URL prefix and gallery visibility on brewpage.app.

Options:
1) public — visible in gallery (default)
2) {auto-suggested 6-8 char slug}
3) Enter custom namespace
4) Skip → use public

Reply with a number or your custom namespace (alphanumeric, 3-32 chars).

Auto-suggest: generate a meaningful short slug (3-16 chars, lowercase alphanumeric + hyphens) from content context:

File → topic/purpose of the file (e.g. api-docs, login-page, report-q2)

Text/HTML → main subject or title (e.g. pricing, team-intro, changelog)

JSON → data type or schema name (e.g. user-config, metrics)

Fallback → project name or directory name if content is ambiguous
Never use random strings or truncated filenames — the slug should be human-readable and describe what's being published.

Resolution:

1, 4, or empty → public

2 → suggested slug

3 or any other string → use as-is

Step 5: Ask Password

Use AskUserQuestion:

Password protection (if set, page is hidden from gallery):

Options:
1) No password (default)
2) Random: {generated 6-char password, e.g. "kx7p2m"}
3) Enter custom password (min 4 chars)
4) Skip → no password

Reply with a number or your custom password.

Generate random password EXECUTE using Bash tool:

LC_ALL=C tr -dc 'a-z0-9' < /dev/urandom | head -c6 2>/dev/null

Resolution:

1, 4, or empty → no password

2 → use generated random password

3 or custom text → use as-is

Step 6: Publish and Save Token (secure)

SECURITY: The ownerToken MUST never appear in conversation output. The bash block below handles curl, token parsing, and history saving atomically. The LLM only sees the URL.

HTML/Markdown text — EXECUTE using Bash tool:

HISTORY_FILE=".claude/brewpage-history.md"
if [ ! -f "$HISTORY_FILE" ]; then
  mkdir -p "$(dirname "$HISTORY_FILE")"
  cat > "$HISTORY_FILE" <<'HEADER'
# brewpage.app — Published Pages

> Owner tokens allow update/delete. Keep this file private.
> Delete: `curl -s -X DELETE "https://brewpage.app/api/{ns}/{id}" -H "X-Owner-Token: TOKEN"`

| Date | URL | Owner Token | TTL |
|------|-----|-------------|-----|
HEADER
fi

CONTENT=$(cat <<'BREWPAGE_EOF'
{content}
BREWPAGE_EOF
)
PAYLOAD=$(jq -n --arg c "$CONTENT" '{content: $c}')
RESPONSE=$(curl -s -X POST "https://brewpage.app/api/html?ns={ns}&ttl={days}&format=markdown" \
  -H "Content-Type: application/json" \
  {password_header} \
  -d "$PAYLOAD")

URL=$(echo "$RESPONSE" | jq -r '.link // empty')
TOKEN=$(echo "$RESPONSE" | jq -r '.ownerToken // empty')

if [ -n "$URL" ]; then
  [ -n "$TOKEN" ] && echo "| $(date '+%Y-%m-%d %H:%M') | [$URL]($URL) | \`$TOKEN\` | {ttl}d |" >> "$HISTORY_FILE"
  echo "✅ $URL"
else
  echo "❌ FAILED: $RESPONSE"
fi

JSON — EXECUTE using Bash tool:

HISTORY_FILE=".claude/brewpage-history.md"
if [ ! -f "$HISTORY_FILE" ]; then
  mkdir -p "$(dirname "$HISTORY_FILE")"
  cat > "$HISTORY_FILE" <<'HEADER'
# brewpage.app — Published Pages

> Owner tokens allow update/delete. Keep this file private.
> Delete: `curl -s -X DELETE "https://brewpage.app/api/{ns}/{id}" -H "X-Owner-Token: TOKEN"`

| Date | URL | Owner Token | TTL |
|------|-----|-------------|-----|
HEADER
fi

RESPONSE=$(curl -s -X POST "https://brewpage.app/api/json?ns={ns}&ttl={days}" \
  -H "Content-Type: application/json" \
  {password_header} \
  -d '{original_json}')

URL=$(echo "$RESPONSE" | jq -r '.link // empty')
TOKEN=$(echo "$RESPONSE" | jq -r '.ownerToken // empty')

if [ -n "$URL" ]; then
  [ -n "$TOKEN" ] && echo "| $(date '+%Y-%m-%d %H:%M') | [$URL]($URL) | \`$TOKEN\` | {ttl}d |" >> "$HISTORY_FILE"
  echo "✅ $URL"
else
  echo "❌ FAILED: $RESPONSE"
fi

File — EXECUTE using Bash tool:

HISTORY_FILE=".claude/brewpage-history.md"
if [ ! -f "$HISTORY_FILE" ]; then
  mkdir -p "$(dirname "$HISTORY_FILE")"
  cat > "$HISTORY_FILE" <<'HEADER'
# brewpage.app — Published Pages

> Owner tokens allow update/delete. Keep this file private.
> Delete: `curl -s -X DELETE "https://brewpage.app/api/{ns}/{id}" -H "X-Owner-Token: TOKEN"`

| Date | URL | Owner Token | TTL |
|------|-----|-------------|-----|
HEADER
fi

RESPONSE=$(curl -s -X POST "https://brewpage.app/api/files?ns={ns}&ttl={days}" \
  {password_header} \
  -F "file=@/absolute/path/to/file")

URL=$(echo "$RESPONSE" | jq -r '.link // empty')
TOKEN=$(echo "$RESPONSE" | jq -r '.ownerToken // empty')

if [ -n "$URL" ]; then
  [ -n "$TOKEN" ] && echo "| $(date '+%Y-%m-%d %H:%M') | [$URL]($URL) | \`$TOKEN\` | {ttl}d |" >> "$HISTORY_FILE"
  echo "✅ $URL"
else
  echo "❌ FAILED: $RESPONSE"
fi

Replace {password_header} with -H "X-Password: {pass}" only when password was set; otherwise remove it entirely.

Step 7: Output Result

Success (bash printed ✅ {url}):

✅ Published!
🔗 {url from bash output}
📁 Owner token saved to .claude/brewpage-history.md

NEVER print ownerToken in conversation. The token is only in the history file.

Error (bash printed ❌ FAILED: ...):

❌ Publish failed.

Notes

Always use absolute file paths with curl -F "file=@...".

Use jq -n --arg c "$CONTENT" '{content: $c}' to safely encode text content. format is a query param, not a body field — /api/html ignores any format key inside the JSON body and reads only ?format= from the URL. Wrong location = server applies default html and stores your markdown as raw text.

TTL default is 15 days.

Namespace must be alphanumeric (3-32 chars). Default: public.

To delete a published page, find the owner token in .claude/brewpage-history.md and use the delete command shown in that file's header.
