How this service works
MCP tool providing real-time financial market data gated by x402 micropayments on Base.
Output
A JSON object containing the symbol, status, and five price fields: current_price, open_price, high_price, low_price, and previous_close — all as numeric values representing the latest available market data for the requested ticker.
Example use cases
Real-time crypto portfolio check
“What's the current price of ETH, along with today's open, high, and low?”
Stock price alert before earnings
“Pull up the latest market data for AAPL — I need the current price, today's high and low, and the previous close.”
Intraday trading decision support
“Give me a live quote for BTC, including the open price, high, low, and where it's trading right now.”
Technical details
Endpoint
POSThttps://mcp-x402-paywall.onrender.com/messages/paid?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call real-time market quote for a single stock or crypto symbol and want to avoid subscription-based data APIs. It is ideal for AI agents that need occasional price lookups without a standing data subscription, and for workflows on Base where USDC micropayments via x402 are already integrated.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty data
- Payment failure (insufficient USDC balance or x402 handshake error) blocks the request
- Market closed or after-hours may return stale or unavailable data
- Rate limiting or server unavailability from the hosted Render instance
- Crypto symbols must match expected format (e.g. BTC not bitcoin)
