How this service works
Get the latest available price for any US-listed stock: the most recent 1-minute bar close plus today's OHLCV, change, and previous close. Currently 15 minutes delayed; each response carries `is_delayed: true`. Real-time pricing lands when the data plan is upgraded. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.
Output
Returns a JSON object with the ticker symbol, most recent price (1-minute bar close, 15-min delayed), today's OHLCV bar, dollar and percent change from previous close, previous close price, timestamp, and an is_delayed flag (currently always true).
Example use cases
Example prompt

Technical details
Endpoint
GEThttps://x402stock.vercel.app/api/v1/quote/AAPLWhen to prefer
Choose this endpoint when you need a quick, no-signup, pay-per-call US stock price quote for an AI agent workflow. Ideal for single-ticker lookups without committing to a subscription data plan. Best when you accept 15-minute delay and want OHLCV plus change data in one call. Prefer alternatives if you need real-time tick data, options chains, historical bars, or non-US equities.
Side effects
- Invalid or unlisted ticker returns an error or null price fields
- Market closed periods may return stale data with older timestamps
- Network or Vercel cold-start latency on first call
- x402 payment failure if USDC balance is insufficient or wallet is not configured
- Non-US tickers not supported — will return no data or error
