How this service works
End-of-day US equity quote from a licensed feed: last close, day range, previous close and the change between them, consolidated across three venues. Use it when an agent needs a current price for a US stock without an exchange account; indices, FX and crypto are not covered here.
Output
A JSON object containing the last traded price, intraday high/low range, 52-week high/low range, previous close, currency, exchange name, and percentage/absolute change relative to previous close for the requested ticker symbol.
Example use cases
Example prompt
“What's the current price of AAPL, including today's range and how it's changed from yesterday's close?”
Technical details
Endpoint
GEThttps://agent402.tools/api/stock-quote?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live, keyless market quote for equities, indices, FX pairs, or crypto with no API key setup and broad symbol coverage. Ideal for agents that need real-time price context without managing credentials or rate limits. Prefer this over dedicated brokerage APIs when you just need a quick price check rather than order execution or historical time series.
Side effects
- Invalid or misspelled ticker symbol returns an error or empty result
- Delisted or obscure symbols may not be found in Yahoo Finance's dataset
- Temporary Yahoo Finance backend outage may cause request failures
- FX symbols require the =X suffix (e.g. EURUSD=X) or they won't resolve correctly
- Crypto symbols require the -USD suffix (e.g. BTC-USD) or they won't resolve
