Stock Quotes API
Last updated:
Access historical end-of-day (EOD) stock prices, intraday 1-minute OHLCV bars, and live-merged daily data through a single API endpoint — where most providers require three or more separate endpoints and manual data stitching. The daily mode automatically injects the latest live trading bar into your historical series during market hours, eliminating the glue code other APIs force you to write. Query one or many tickers at once — multi-ticker responses return a dictionary keyed by ticker, each with isolated metadata and data blocks, not a mixed flat array. The API is free to use.
Three data modes in one endpoint:

Stock Price API Capabilities
Most stock price APIs split EOD, intraday, and live data across separate endpoints — often three or more. This endpoint unifies all three behind a single mode parameter, returning the same clean OHLCV structure regardless of resolution, paginated and filterable by date.
Historical EOD Prices
Clean, historical end-of-day OHLCV data spanning multiple years — suitable for backtesting trading rules, factor strategies, and historical performance analysis across long time horizons.
Intraday 1-Minute Bars
High-resolution intraday price series at 1-minute intervals via mode=minute-bars. Use for intraday strategy development, event-driven analysis, and session-level monitoring.
Smart Daily Mode
mode=daily returns historical EOD data and, during active market hours, automatically appends the latest live bar at the top — one endpoint for both historical and current-day data.
Multi-Ticker Support
Request multiple tickers in a single call with ticker=AAPL,MSFT. The response is a dictionary keyed by ticker — each with its own isolated metadata and data blocks — instead of a mixed flat array.
Flexible Time Filters
Use relative period strings (1d, 1mo, 1y) or explicit from_date/till_date in YYYY-MM-DD format to define the historical window for any resolution mode.
Robust Pagination
Every response's metadata.pagination object includes current_page, limit, total_records, and total_pages so you can reliably iterate through large historical price series.
EOD, Daily & Intraday Data Modes
The mode parameter controls the resolution and live-data behavior of the response. All three modes use the same endpoint URL and return the same OHLCV field structure — no need to learn separate APIs or parse different response schemas.
1. Request Parameters
The Quotes endpoint uses URL query parameters to define the target securities, the data resolution (EOD vs intraday), and the historical horizon. Query one or many tickers, choose between smart daily, strictly historical EOD closes, or intraday 1-minute bars, and control how much history you retrieve using period or explicit from_date/till_date bounds.

2. Architecture: Multi-Ticker & Smart Daily Merging
Two behaviors of this endpoint distinguish it from a standard price feed — multi-ticker dictionary wrapping and automatic live-bar injection in daily mode. Understanding both prevents integration surprises when parsing responses.
1. Multi-Ticker Output Structure
When querying multiple tickers (e.g., ticker=AAPL,MSFT), the API returns a dictionary object keyed by ticker — each containing its own isolated metadata and data blocks. This avoids mixing price series from different companies into a flat array and makes per-ticker access O(1) by key.
{
"AAPL": {
"metadata": { ... },
"data": [ ... ]
},
"MSFT": {
"metadata": { ... },
"data": [ ... ]
}
}
2. Real-Time Interim Merging (Daily Mode)
When fetching daily data during active market hours, the API queries the Interim Real-Time Engine and injects the current live trading bar at index 0 of the data array — merging historical EOD and live data into one continuous stream without a separate endpoint.
Smart EOD Lock-in
If the market has closed but EOD processing hasn't completed, the live bar locks in at 16:00:00. This guarantees you always have the latest daily close without polling a separate real-time endpoint or waiting for batch finalization.
3. Coverage & Data Details
Scope, field definitions, and update cadence for both the historical EOD and intraday 1-minute price series.
Instruments & Markets
Historical EOD and intraday 1-minute prices for US-listed equities and ETFs. Use a valid exchange ticker symbol as the identifier — the same symbol accepted by the Company Profile API and Stock Screener API.
OHLCV Fields
Every record in the data array contains six fields: date (timestamp for the period), open, high, low, close (all in the trading currency), and volume (shares traded during the interval). For EOD records the timestamp resolves to 16:00:00; for intraday minute bars it reflects the bar open time.
Historical Depth
End-of-day price history extends back many years for actively traded large-caps and ETFs — use period=all or set wide explicit dates to retrieve the full available range. Intraday 1-minute bars cover a rolling recent window; use mode=eod or mode=daily for long historical lookbacks and mode=minute-bars for high-frequency recent sessions.
Update Cadence
Intraday bars are refreshed continuously during market hours. The live bar injected by mode=daily reflects the most recent trading activity. EOD records are finalized after market close once official end-of-day processing completes — typically within minutes of the 16:00 ET session close.
Pagination for Long Histories
When pulling multi-year historical series, use limit and page together and iterate using metadata.pagination.total_pages to know when to stop. Each page is guaranteed to be consistent — the total_records count does not change between pages for the same query.

Frequently Asked Questions
What data modes does the Stock Quotes API support?
Three modes: daily returns historical EOD prices and, during active market hours, automatically injects the latest live trading bar at index 0. eod returns only confirmed end-of-day closes with no live data — ideal for backtesting. minute-bars returns intraday 1-minute OHLCV bars.
Can I request prices for multiple tickers in one API call?
Yes. Pass a comma-separated list (e.g., ticker=AAPL,MSFT,GOOGL). The response returns a dictionary keyed by ticker, each with its own metadata and data blocks, rather than a mixed flat array.
How does the daily mode differ from eod mode?
The eod mode returns only completed, confirmed end-of-day closing prices — ideal for backtesting and factor models. The daily mode returns the same historical data but, during active market hours, automatically injects the latest live trading bar at index 0, merging historical and current-day data into one seamless series.
What time periods can I query?
Use relative period strings (1d, 1w, 1mo, 3mo, 1y, 5y) or explicit from_date/till_date in YYYY-MM-DD format. Results are paginated with total_records and total_pages in the metadata.
Is the Stock Quotes API free to use?
Yes, the Stock Quotes API is free to use. Sign up for an API key to start pulling EOD prices, intraday bars, and live daily data immediately.
