How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON array of quote results, each containing the stock symbol, current price, open, high, low, volume, and the underlying data source (Twelve Data). Example: {results:[{symbol:'AAPL',price:'348.32',open:'347.0',high:'350.0',low:'346.0',volume:'1234567',source:'twelvedata'}]}
Example use cases
Real-time portfolio valuation check
“Pull the latest stock quotes for AAPL, MSFT, and GOOGL so I can see today's prices and how my portfolio is doing right now.”
Trading signal trigger
“Fetch the current price and today's high and low for TSLA — I want to know if it's trading near its daily high before I make a move.”
Earnings day price monitoring
“What's the live quote for NVDA right now? I want the price, open, and volume to see how the market is reacting after the earnings report.”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/stock-quotes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time stock quote data (price, OHLV) without signing up for an account or managing API keys, and you are comfortable paying $0.002 USDC per call on Base via the x402 protocol. It is ideal for AI agents in crypto-native environments that already handle x402 micropayments, and for lightweight use cases that do not require historical data, options chains, or fundamentals.
Side effects
- Missing or invalid ticker symbol returns an error or empty results array
- Payment not completed via x402 results in HTTP 402 response before data is returned
- Rate limits or upstream Twelve Data outages may cause delayed or failed responses
- Requesting a non-existent or delisted symbol may return no results
- Network issues with the duckdns.org dynamic DNS host may cause connectivity failures
