How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
A JSON object containing the ticker symbol, quote date, last price, open, day high/low, change and percent change from previous close, 50-day and 200-day moving averages, 52-week high and low, latest and average trading volume (10-day and 3-month), market cap, currency, and exchange name.
Example use cases
Portfolio price check before trading
“Pull the latest quote for NVDA — I need the current price, today's change percentage, and the 52-week high before I decide whether to buy.”
Earnings day context lookup
“MSFT just reported earnings — what's the stock trading at right now compared to its previous close, and what's the volume relative to its 3-month average?”
Automated market summary agent
“Every morning, get me the current price, day range, and market cap for AAPL, TSLA, and GOOGL so I can see how they opened.”
Technical details
Endpoint
GEThttps://x402financialdata.com/quote/%7Bticker%7DWhen to prefer
Choose this endpoint when you need frictionless, pay-per-call stock quotes with no API key registration or subscription — ideal for low-frequency lookups, agent pipelines, or scenarios where you want to pay only for what you use in USDC. Prefer it over subscription-based data providers when cost predictability at micro-scale matters or when operating in a crypto-native environment using the x402 payment protocol.
Side effects
- Invalid or unknown ticker symbol returns an error or empty response
- Payment failure (insufficient USDC balance or network issues) causes a 402 response blocking data delivery
- Market closed or pre/after-hours data may reflect stale or delayed prices
- Rate limiting or network timeouts on Base or Solana payment rails delay the call
- Ticker format mismatch (e.g. using exchange-prefixed symbol instead of bare ticker)
