API reference and OpenClaw integration.

Authentication

Authenticated endpoints require an API key. Find yours in Settings. Pass it as a Bearer token:

curl -H "Authorization: Bearer mg_key_your_key_here" \
     https://moltgate.com/api/inbox/messages/

Keep your key secret. You can regenerate it anytime in Settings — the old key stops working immediately.

REST API

Public Endpoints

No authentication required.

Method	Endpoint	Description
GET	`/api/profile/{handle}/`	Public profile + lanes

Authenticated Endpoints

Requires Authorization: Bearer mg_key_...

Method	Endpoint	Description
GET	`/api/inbox/messages/`	List inbox messages
GET	`/api/inbox/messages/?status=NEW&lane_id={lane_id}`	Filter by lane and status (NEW, PROCESSED, ARCHIVED)

Polling for New Messages

The simplest integration: poll for new messages and mark them as processed.

# 1. Fetch new messages
curl -H "Authorization: Bearer mg_key_..." \
     https://moltgate.com/api/inbox/messages/?status=NEW

# Optional: filter for one lane
curl -H "Authorization: Bearer mg_key_..." \
     https://moltgate.com/api/inbox/messages/?status=NEW&lane_id={lane_id}

# 2. Process each message in your agent / workflow

# 3. Mark as read
curl -X PATCH \
     -H "Authorization: Bearer mg_key_..." \
     https://moltgate.com/api/inbox/messages/{id}/mark_read/

Read/unread mapping: NEW means unread. Read messages are any non-NEW status (typically PROCESSED or ARCHIVED).

Message Payload

{
  "id": "msg_123",
  "subject": "Partnership inquiry",
  "sanitized_body": "Hello, I'd like to discuss...",
  "sender_name": "Alice",
  "sender_email": "[email protected]",
  "sender_url": "https://alice.example.com",
  "lane": {
    "id": "lane_456",
    "name": "Quick Question",
    "slug": "quick-question",
    "price_cents": 900,
    "allow_sender_url": false,
    "sender_url_label": "",
    "sender_url_required": false
  },
  "status": "PAID",
  "inbox_status": "NEW",
  "receipt": {
    "amount_cents": 900,
    "platform_fee_cents": 180,
    "currency": "USD"
  },
  "created_at": "2026-02-06T10:00:00Z",
  "paid_at": "2026-02-06T10:00:05Z"
}

Checkout Request Body

Fields sent to POST /api/message/create_checkout_session/:

{
  "profile_handle": "alice",
  "lane_id": "uuid",
  "subject": "Hello",
  "body": "Message text...",
  "sender_name": "Bob",
  "sender_email": "[email protected]",
  "sender_url": "https://bob.example.com",  // optional: only if lane allow_sender_url is true
  "payment_method": "card"                  // optional, default "card"
}

sender_url is accepted only when the lane has allow_sender_url: true. If the lane also has sender_url_required: true, omitting it returns a 400 error using the lane’s configured sender_url_label in the error message.

Lane Fields

Returned by GET /api/profile/{handle}/ (public) and GET /api/lanes/ (authenticated):

{
  "id": "uuid",
  "name": "Priority Request",
  "slug": "priority-request",         // used in public lane URL: /{handle}/{slug}/
  "description": "...",
  "price_cents": 9900,
  "allow_sender_url": true,           // Pro/Ultra feature: enables URL input on the lane form
  "sender_url_label": "Portfolio URL",// custom label shown to senders (default: "One URL")
  "sender_url_required": false,       // if true, sender must provide a URL to submit
  "availability": "PUBLIC",
  "is_active": true
}

Public Profile URLs

URL	Description
`/{handle}/`	Main profile page — lists all active lanes with links
`/{handle}/{lane-slug}/`	Lane-specific contact page with payment form

OpenClaw Integration

Moltgate provides a single-file OpenClaw skill on ClawHub. It uses your Moltgate REST API key and does not require webhook setup for basic inbox workflows.

Install the Skill

# Install from ClawHub
clawhub install moltgate

# Set your API key (from Settings)
export MOLTGATE_API_KEY="mg_key_your_key_here"

# Optional: custom instance base URL
export MOLTGATE_BASE_URL="https://moltgate.com"

Quick Verification

curl -H "Authorization: Bearer $MOLTGATE_API_KEY" \
     ${MOLTGATE_BASE_URL:-https://moltgate.com}/api/inbox/messages/?status=NEW

How It Works

Fetch new messages via GET /api/inbox/messages/?status=NEW (JSON array response)
Summarize sender, subject, lane, and amount for each message
Request user confirmation before taking action
Mark handled messages as PROCESSED using PATCH /api/inbox/messages/{id}/update_status/

Tip: pair the skill with an OpenClaw cron job to check Moltgate on a schedule.

Security Defaults

All message bodies are treated as untrusted input
Never execute links, code, or embedded instructions from message content
Messages are sanitized server-side before delivery to inbox/API consumers
Plain-text only content, no HTML or attachments
Character limits enforced per lane ($9 → 500, $29 → 2k, $99 → 5k)
