REST API (Alternative)

Data Privacy & What Gets Sent

The server requires only the tool call parameters listed below. What your MCP client actually transmits depends on the client implementation — please review your MCP client's privacy and transport settings to verify.

Specifically, each tool requires:

get_kimchi_premium, get_global_vs_korea_divergence, get_global_vs_korea_divergence_deep: symbol parameter only (e.g., "BTC")
get_kr_prices: symbol and exchange parameters only
get_kr_news_kpop, get_kr_news_kpop_summary, get_kr_news_semiconductor, get_kr_news_semiconductor_summary: optional limit parameter only (1-10, default 5)
get_arbitrage_scanner, get_exchange_alerts, get_market_movers: no parameters — server computes from cached exchange data
get_market_read: no parameters — server fetches all data internally and runs AI analysis server-side
get_kr_sentiment: no parameters — server combines exchange data with Korean news context and runs AI sentiment analysis server-side
get_fx_rate, get_stablecoin_premium, get_available_symbols, check_health: no parameters

Note: Like any HTTP service, the server receives standard HTTP metadata (IP address, user-agent) as part of normal network communication.

Network calls only to: mcp.printmoneylab.com and api.printmoneylab.com

Payment Authorization (x402 Protocol)

How x402 payment works — step by step:

Agent calls a paid endpoint (e.g., get_kimchi_premium)
Server returns HTTP 402 with price in the payment-required header
The MCP client or platform decides whether to pay — this is NOT automatic
If the client approves, it signs a USDC transfer for the exact amount on Base, Polygon, or Solana
Client retries with payment proof in X-PAYMENT header
Server verifies payment and returns data

Key points:

Payment is NOT automatic. The agent's MCP client (e.g., xpay Smart Proxy, Claude, Cursor) controls whether to authorize payment.
No wallet keys or credentials are stored in this skill. Payment is handled entirely by the MCP client's x402 transport layer.
The skill cannot charge without explicit client-side authorization. The x402 protocol requires a cryptographic signature from the buyer's wallet.
Cost per call: $0.001 (basic data) to $0.10 (AI deep analysis). No subscriptions, no hidden fees.

Receipt Verification

Every paid response includes a signed receipt for agent accountability. Bots can verify receipt authenticity using the merchant's public key.

The server returns a receipt field in every paid response:

json

{
  "receipt": {
    "id": "rcpt_20260513_a3f9c1",
    "issued_at": "2026-05-13T07:30:00.000Z",
    "endpoint": "/api/v1/kimchi-premium",
    "amount": "0.001",
    "currency": "USDC",
    "network": "eip155:8453",
    "tx_hash": "0x...",
    "payer": "0x...",
    "merchant": "0xcF9223eCe895258dEa8D288AEBcf846Ab8E342fB",
    "signature": "0x...",
    "signer": "0x1AdF0f9e576E94a150208F08D2C31F791932E781"
  }
}

Verification (Python):

python

from eth_account import Account
from eth_account.messages import encode_defunct

payload = "|".join([
    r["id"], r["endpoint"], r["amount"], r["currency"],
    r["network"], r["tx_hash"], r["payer"], r["merchant"], r["issued_at"]
])
recovered = Account.recover_message(
    encode_defunct(text=payload),
    signature=r["signature"]
)
# recovered.lower() == r["signer"].lower() → authentic

Merchant public key is published at: https://api.printmoneylab.com/.well-known/x402 under receipt_signer.public_key

Receipt verification is optional but recommended for agents that need to maintain audit logs or reconcile payments.

Autonomous Invocation Advisory

This skill is designed to be invoked by the agent when the user asks about Korean crypto markets, Korean financial news, K-pop news, or Korean semiconductor industry news. If your platform supports invocation controls:

Recommended: Set to "user-invoked only" until comfortable with billing behavior
Budget: Configure your MCP client's spending limit
Maximum cost per session: Bounded by your client's spending policy

Security

No local code execution — instruction-only skill
No credentials stored — no API keys, no wallet keys, no env vars
No file system access — all data from remote API
