Moltpho Shopping Skill

Shop for items on Amazon autonomously using credit-backed mUSD tokens on Base mainnet.

Overview

Moltpho is a headless shopping mall that enables AI agents to discover and purchase Amazon products using a credit system backed by mUSD (an ERC-20 token on Base mainnet). This skill handles:

• Agent registration and credential management
• Product search and discovery
• Autonomous and proactive purchasing
• Credit balance monitoring
• x402 payment protocol integration

Bootstrap Flow

On first invocation, the skill MUST check for existing credentials and register if needed.

Credentials Location

Registration Process

1. Check credentials file at the appropriate path
2. If missing, call POST /v1/agents/register with:

- openclaw_instance_id (if available) - agent_display_name - agent_description - No shipping profile required at registration

1. Save credentials with chmod 600 permissions
2. Auto-open browser with notice: "Opening portal in your browser to complete setup..."
3. Registration proceeds WITHOUT shipping profile - orders will fail until owner adds one via portal

Credentials File Format

{
  "agent_id": "uuid",
  "api_key_id": "moltpho_key_...",
  "api_key_secret": "moltpho_secret_...",
  "api_base_url": "https://api.moltpho.com",
  "wallet_address": "0xabc123..."
}

Core Functions

bootstrap()

Initialize agent credentials and open portal for owner setup.

1. Check if credentials file exists at platform-specific path
2. If exists and valid: load credentials, verify with GET /v1/agents/me
3. If missing or invalid:
   a. Call POST /v1/agents/register (no auth required)
   b. Receive: agent_id, api_key_id, api_key_secret, claim_url, wallet_address
   c. Write credentials file with chmod 600
   d. Display: "Opening portal in your browser to complete setup..."
   e. Open browser to claim_url (valid for 24 hours)
4. Return agent status (UNCLAIMED, CLAIMED, DEGRADED, SUSPENDED)

collect_shipping_profile()

Optionally collect shipping information from the owner.

Note: This is OPTIONAL. Owners can configure shipping via the portal instead.
      Orders will fail with INVALID_SHIPPING_PROFILE until a profile exists.

If collecting in conversation:
1. Request full name
2. Request address (street, city, state, ZIP)
3. Request email
4. Request phone
5. Validate: US addresses only (international not supported in v1)
6. Call POST /v1/shipping_profiles (upsert_shipping_profile)
7. Confirm profile saved

The POST endpoint upserts the default profile:
- If no profile exists, creates one
- If a profile exists, updates it

update_shipping_profile()

Update the shipping address for the agent.

Parameters:
- full_name: Recipient full name
- address1: Street address

2. CREATE QUOTE: Call POST /v1/quotes
   - Include: asin, quantity, shipping_profile_id
   - Returns: quote_id, total_due_usd, expires_at (10 min TTL)
   - Creates soft reservation against balance
   - May fail with INVALID_SHIPPING_PROFILE if no profile set

3. INITIATE ORDER: Call POST /v1/orders with quote_id
   - First call returns 402 Payment Required with PAYMENT-REQUIRED header

4. SIGN PAYMENT: Call POST /v1/wallets/x402/sign
   - Include: payment_required blob, idempotency_key
   - Returns: payment_signature for x402 header

5. COMPLETE ORDER: Retry POST /v1/orders with PAYMENT-SIGNATURE header
   - On success: returns order_id, status (PAID/PLACED)
   - Soft reservation converted to actual spend

Auto-retry on quote expiry:
- If quote expires during flow, automatically retry up to 3 times
- Only retry if new price is within 5% of original quote
- Fail after 3 retries or if price changed >5%

Rate limits:
- Quotes: 20/minute
- Orders: 5/minute
- Signing: 10/minute

proactive_monitoring()

Watch conversation for purchase need signals and act when appropriate.

This function runs passively during conversation to detect purchase opportunities.

NEED SIGNALS (explicit):
- "I need", "we're out of", "buy", "order", "replace"
- "running low on", "almost out of"
- Direct product mentions with urgency

NEED SIGNALS (implicit):
- Repeated complaints about missing items
- Critical item shortages mentioned
- Context suggesting immediate need

CONFIDENCE SCORING:
- 1.0: Explicit purchase request ("buy me X")
- 0.8: Strong implied need ("we're completely out of toilet paper")
- 0.5: Weak implied convenience (do NOT buy)
- 0.0: Unknown/unclear

BUDGET SIGNAL HANDLING:
- Phrases like "money is tight", "on a budget", "can't afford"
- Reduce confidence by 0.3-0.5
- Proceed cautiously if still above threshold

PROACTIVE PURCHASE ALLOWED IF ALL TRUE:
- Owner has enabled proactive purchasing (default ON)
- Confidence >= 0.8 (threshold)
- Item matches low-risk categories:
  - Household essentials
  - Office supplies
  - Cables/adapters
  - Basic kitchen items
  - Toiletries
- Price <= min(per_order_cap, $75)
- Item keywords not in denied categories
- Item not in system blocklist
- Shipping profile exists

LOGGING:
Every purchase logs:
- "why we bought" (decision reason)
- Signals detected
- Confidence tier (HIGH/MEDIUM/LOW)
- Budget impact

budget_check()

Verify sufficient credit before any purchase.

Process:
1. Call GET /v1/balance
2. Response includes:
   - available_credit_cents: Spendable amount
   - staged_refunds: Pending refunds (shown with asterisk)
   - target_limit: Owner's configured credit limit
3. Compare against:
   - Quote total
   - per_order_cap (if set)
   - daily_cap (if set, track daily spending)
4. Return: can_purchase (bool), available_amount, reason_if_blocked

create_support_ticket(type, description, order_id)

Create a support ticket for returns, lost packages, or other issues.

Parameters:
- type: Ticket type - RETURN, LOST_PACKAGE, or OTHER
- description: Detailed description of the issue (1-2000 chars)
- order_id: Order ID (required for RETURN and LOST_PACKAGE)

Process:
1. Validate ticket type and description
2. If RETURN or LOST_PACKAGE, verify order_id is provided
3. Call POST /v1/support_tickets with { type, description, order_id }
4. Return ticket ID and status

Use cases:
- "I want to return this item" → type=RETURN, link to order

- "I have a question about billing" → type=OTHER, no order needed

Note: Returns and lost packages require a support ticket.
      Automated refunds only happen for order cancellations.

list_support_tickets()

List the agent's support tickets.

Process:
1. Call GET /v1/support_tickets
2. Display tickets with: type, status, order link, creation date
3. Status meanings:
   - OPEN: Submitted, awaiting support review
   - IN_PROGRESS: Being handled
   - WAITING_CUSTOMER: Support needs more info from you
   - RESOLVED: Issue resolved
   - CLOSED: Ticket closed

logout()

Delete local credentials (agent persists server-side).

Process:
1. Delete credentials file at platform-specific path
2. Display: "Credentials removed. Agent still exists on Moltpho servers."
3. To fully delete agent, owner must use portal

Note: This only removes LOCAL credentials. The agent account, wallet, and
      purchase history remain on Moltpho servers until owner deletes via portal.

Browser Portal Usage

The skill uses the browser for owner-sensitive operations.

When to Open Browser

Browser Guidelines

• Always display notice: "Opening portal in your browser..."
• NEVER request card numbers, passwords, or sensitive credentials in chat
• Portal handles all PCI-sensitive operations via Stripe Elements
• Owner authenticates via magic link (email-based)

API Authentication

All API requests (except registration) require authentication.

Headers

Authorization: Bearer <api_key_secret>

Or preferably:

X-Moltpho-Key-Id: <api_key_id>
X-Moltpho-Signature: <HMAC signature>

Idempotency

For state-changing operations, always include:

Idempotency-Key: <unique-key>

Required for:

• POST /v1/quotes
• POST /v1/orders
• POST /v1/wallets/x402/sign

Error Handling

Common Errors

Quote Expiry Auto-Retry

When a quote expires during the x402 flow:

1. Fetch new quote for same item
2. Compare price to original quote
3. If within 5% tolerance: continue with new quote
4. If >5% change: fail with PRICE_CHANGED
5. Maximum 3 retry attempts
