Alpha Vantage — Financial Market Data

Access 20+ years of global financial data: equities, options, forex, crypto, commodities, economic indicators, fundamentals, news sentiment, and 50+ technical indicators — all from one /query endpoint.

When to Use This Skill

Pulling OHLCV price history or a latest quote for a ticker, FX pair, or crypto asset
Fetching pre-computed company fundamentals (overview ratios, statements, earnings, dividends, splits)
Computing technical indicators server-side (SMA, EMA, RSI, BBANDS, ...)
Retrieving commodity prices or headline US macro series (GDP, CPI, yields, unemployment)
News-sentiment, earnings-call transcripts, or insider transactions for event studies

Does NOT Trigger

Scenario	Use Instead
Macro series by FRED ID (UNRATE, GDPC1), server-side `pc1` transforms, ALFRED vintages	`alterlab-fred`
Line items from the actual 10-K/10-Q, XBRL facts, Form 4/13F filings from SEC EDGAR	`alterlab-edgartools`
Treasury debt to the penny, Daily/Monthly Treasury Statements, auction results	`alterlab-usfiscaldata`
Aggregate hedge-fund leverage / SEC Form PF statistics	`alterlab-hedgefund-monitor`
Fitting ARIMA/regression models to the series you downloaded	`alterlab-statsmodels`

API Key Setup (Required)

Get a free key at https://www.alphavantage.co/support/#api-key (premium plans raise limits and unlock premium endpoints)
Set as environment variable:

export ALPHAVANTAGE_API_KEY="your_key_here"

If an Alpha Vantage MCP connector is configured (Alpha Vantage runs an official MCP server, see https://mcp.alphavantage.co/), prefer it for live lookups; the REST patterns below work everywhere.

Installation

uv pip install requests pandas

Base URL & Request Pattern

All requests go to:

https://www.alphavantage.co/query?function=FUNCTION_NAME&apikey=YOUR_KEY&...params

import os
import requests

API_KEY = os.environ.get("ALPHAVANTAGE_API_KEY")
BASE_URL = "https://www.alphavantage.co/query"

def av_get(function, **params):
    response = requests.get(BASE_URL, params={"function": function, "apikey": API_KEY, **params}, timeout=30)
    response.raise_for_status()
    data = response.json()
    # Alpha Vantage reports errors and limit hits with HTTP 200 + one of these keys
    for key in ("Error Message", "Information", "Note"):
        if key in data:
            raise RuntimeError(f"Alpha Vantage {key}: {data[key]}")
    return data

Quick Start Examples

# Stock quote (latest price; end-of-day unless you have a realtime entitlement)
quote = av_get("GLOBAL_QUOTE", symbol="AAPL")
price = quote["Global Quote"]["05. price"]

# Daily OHLCV: compact = latest 100 points (free); outputsize="full" (25+ years) is premium-only
daily = av_get("TIME_SERIES_DAILY", symbol="AAPL", outputsize="compact")
ts = daily["Time Series (Daily)"]

# Company fundamentals
overview = av_get("OVERVIEW", symbol="AAPL")
print(overview["MarketCapitalization"], overview["PERatio"])

# Income statement
income = av_get("INCOME_STATEMENT", symbol="AAPL")
annual = income["annualReports"][0]  # Most recent annual

# Crypto price
crypto = av_get("DIGITAL_CURRENCY_DAILY", symbol="BTC", market="USD")

# Economic indicator
gdp = av_get("REAL_GDP", interval="annual")

# Technical indicator
rsi = av_get("RSI", symbol="AAPL", interval="daily", time_period=14, series_type="close")

* Premium-only (per the live documentation, checked 2026-09-23). Premium-gated parameters on free functions: outputsize=full on TIME_SERIES_DAILY, and entitlement=realtime|delayed on quotes.

Common Parameters

Parameter	Values	Notes
`outputsize`	`compact` / `full`	compact = last 100 points; full = 20+ years (premium for TIME_SERIES_DAILY)
`datatype`	`json` / `csv`	Default: json
`interval`	`1min`, `5min`, `15min`, `30min`, `60min`, `daily`, `weekly`, `monthly`	Depends on endpoint
`adjusted`	`true` / `false`	Adjust for splits/dividends
`entitlement`	`realtime` / `delayed`	Premium; omit for historical/end-of-day data

Rate Limits and Tiers

Free key: 25 requests/day. Plan the calls before looping over symbols — a 30-ticker panel exhausts the daily quota. Cache responses to disk and reuse them.
Premium plans are sold by requests per minute (75 to 1,200/min) and unlock the starred functions above.
Limit hits and errors arrive as HTTP 200 with an Information (older responses: Note) or Error Message key instead of data, so check the JSON body rather than the status code; the av_get helper above raises on them.

Error Handling

try:
    data = av_get("GLOBAL_QUOTE", symbol="AAPL")
except RuntimeError as err:
    # "Information" usually means the daily quota is used up or the call needs a premium key;
    # "Error Message" usually means a bad function/parameter/symbol.
    print(err)
