DATAFRAMEpandas.DataFrame or polars.DataFrameReturns a DataFrame with quotes indexed by symbol (default).
INTERNALlist[StockQuote] or list[StockQuotesHumanReadable]Returns a list of StockQuote objects. When use_human_readable=True, returns a list of StockQuotesHumanReadable objects with capitalized field names.
JSONdictReturns the raw JSON response as a dictionary.
CSVstrWrites CSV data to file and returns the filename string.

def quotes(
    symbols: list[str] | str,
    *,
    use_52_week: bool = None,
    extended: bool = None,
    output_format: OutputFormat = OutputFormat.DATAFRAME,
    date_format: DateFormat = None,
    columns: list[str] = None,
    add_headers: bool = None,
    use_human_readable: bool = False,
    mode: Mode = None,
    filename: str | Path = None,
) -> list[StockQuote] | list[StockQuotesHumanReadable] | dict | str | MarketDataClientErrorResult

Fetches stock quotes for one or more symbols. The symbols parameter can be passed as the first positional argument or as a keyword argument. All other parameters must be keyword-only.

Parameters​

  • symbols (list[str] | str)

    A single symbol string or a list of symbol strings for which to fetch quotes.

  • use_52_week (bool, optional)

    Whether to use the 52 week high and low. Uses API alias 52week.

  • extended (bool, optional)

    Whether to use the extended quotes.

  • output_format (OutputFormat, optional)

    The format of the returned data. Defaults to OutputFormat.DATAFRAME. See Settings for details.

  • date_format (DateFormat, optional)

    The date format to use in the response. Defaults to DateFormat.UNIX. See Settings for details.

  • columns (optional)

    Specify which columns to include in the response. If not provided, all available columns are returned. See Settings for details.

  • add_headers (optional)

    Whether to include headers in the response. Uses API alias headers. See Settings for details.

  • use_human_readable (optional)

    Whether to use human-readable format for values. Uses API alias human. Only applies when output_format=OutputFormat.INTERNAL. See Settings for details.

  • mode (Mode, optional)

    The data mode to use. Available options: Mode.LIVE, Mode.CACHED, Mode.DELAYED. See Settings for details.

  • filename (str | Path, optional)

    File path for CSV output (only used with output_format=OutputFormat.CSV). Must end with .csv. Directory must exist. File must not already exist. If not provided, a timestamped file is created in output/ directory.

Returns​

  • list[StockQuote] | list[StockQuotesHumanReadable] | dict | str | MarketDataClientErrorResult

    The quotes data in the requested format, or a MarketDataClientErrorResult if an error occurred.

Notes​

  • When using OutputFormat.DATAFRAME, the DataFrame is indexed by the symbol column.
  • When using OutputFormat.INTERNAL, timestamps are automatically converted to datetime.datetime objects.
  • When using OutputFormat.CSV, the method writes to a file and returns the filename string.
from marketdata import MarketDataClient

client = MarketDataClient()

# Get stock quotes as DataFrame (default)
# symbols can be passed positionally or as keyword
df = client.stocks.quotes("AAPL")
# or
df = client.stocks.quotes(symbols="AAPL")

# Get quotes for multiple symbols
df = client.stocks.quotes(["AAPL", "MSFT"])

print(df)
