How this service works
Returns the last price for a US stock, 15 minute delayed.
Output
Returns a JSON object containing the ticker symbol, the most recent 1-minute bar close price, today's OHLCV (open, high, low, close, volume, VWAP), the absolute change and percentage change from the prior close, the previous close value, a timestamp, and flags indicating whether the data is delayed (currently always true at 15-minute delay) and by how much.
Example use cases
Portfolio value snapshot
“Can you pull the latest quotes for AAPL, MSFT, and GOOGL so I can see how my portfolio is doing today — current price and percentage change for each?”
Pre-trade price check
“Before I decide whether to buy, what is Tesla (TSLA) trading at right now, and what was its previous close?”
Daily market open monitor
“What did SPY open at this morning and where is it trading now — is it up or down from yesterday's close?”

Endpoint
GEThttps://agents.x402stock.xyz/api/v1/quote/{ticker}?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, current price snapshot for a US-listed stock or ETF and do not require a full order book or streaming feed. It is ideal for agents that need to check a stock price on demand without managing API keys or subscriptions — payment is per-call in USDC via x402. Prefer this over historical endpoints when you only need the latest quote, not a time series.
Side effects
- Invalid or unknown ticker symbol returns an error response
- Market closed or pre-market hours may yield stale or null price fields
- Network or payment failure may prevent the request from completing
- is_delayed is always true on the current plan — real-time data requires a plan upgrade
- Tickers not listed on US exchanges are not supported

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
