What Alpha Vantage (BYOK) is for

Alpha Vantage (BYOK) lets an AI assistant read your own Alpha Vantage data through the Alpha Vantage API with a key you supply (API key). Read-only: 6 tools (get_quote, get_daily_prices, get_weekly_prices, get_monthly_prices, search_symbols, get_market_status). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to www.alphavantage.co. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Alpha Vantage. Alpha Vantage and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

  • "What is IBM's latest stock price?"
  • "Show IBM's daily closing prices for the last few months"
  • "Show IBM's weekly prices over the long term"
  • "Show IBM's monthly prices over the past decades"
  • "What is the ticker symbol for Microsoft?"
  • "Are the stock markets open right now?"

What it does

  • get_quote: Get the latest price quote for one ticker: open, high, low, price, volume, previous close and change. By default the quote updates at the end of each trading day; real-time US data needs a premium plan. Free keys are limited to 25 requests per day, and the provider answers with a notice instead of data when the limit is reached.
  • get_daily_prices: Get daily open, high, low, close and volume for one ticker, newest first, for the latest 100 trading days. Free keys are limited to 25 requests per day, and the provider answers with a notice instead of data when the limit is reached.
  • get_weekly_prices: Get weekly open, high, low, close and volume for one ticker over 20+ years, dated on the last trading day of each week. The answer is long and may be cut off. Free keys are limited to 25 requests per day, and the provider answers with a notice instead of data when the limit is reached.
  • get_monthly_prices: Get monthly open, high, low, close and volume for one ticker over 20+ years, dated on the last trading day of each month. Free keys are limited to 25 requests per day, and the provider answers with a notice instead of data when the limit is reached.
  • search_symbols: Search for ticker symbols by company name or keywords; returns best matches with symbol, name, type, region and match score. Free keys are limited to 25 requests per day, and the provider answers with a notice instead of data when the limit is reached.
  • get_market_status: Show whether the major stock, forex and crypto trading venues worldwide are open or closed right now. Free keys are limited to 25 requests per day, and the provider answers with a notice instead of data when the limit is reached.

BYOK key

You bring your own Alpha Vantage API key (https://www.alphavantage.co/support/#api-key). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to www.alphavantage.co over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

Live from the Alpha Vantage API (www.alphavantage.co) with a BYOK key; documentation: https://www.alphavantage.co/documentation/. Endpoints checked against that documentation on 2026-10-16.
