Alpha Vantage is a Boston, Massachusetts based financial data company that sells programmatic access to market data rather than operating a trading venue or terminal itself. Its core product is a set of cloud based REST APIs, returning data in JSON or CSV, covering US and global equities, ETFs, mutual funds, market indices, foreign exchange rates, cryptocurrencies, commodities, company fundamentals, macroeconomic indicators, and more than 50 technical indicators calculated server side. It also ships spreadsheet add ins and an official Model Context Protocol (MCP) server that exposes its endpoints as callable tools to AI coding assistants and agents such as Claude, Cursor and VS Code extensions. The company targets individual developers, students, quantitative researchers and small fintech teams with a self serve, freemium model: a free API key capped at 25 requests per day covering most datasets, plus paid tiers running from $49.99 to $249.99 per month priced by requests per minute rather than the negotiated enterprise contracts typical of incumbent terminal vendors. Its clearest differentiator is direct exchange licensing rather than scraped or unofficial data: Alpha Vantage is listed on Nasdaq's official Vendor List as an approved distributor of realtime and 15 minute delayed US market data, and its own policy pages note that realtime or 15 minute delayed US quotes are only unlocked on its paid tiers. It also cultivates an open source developer ecosystem, publishing wrapper libraries and cataloguing community built clients in languages including Python and JavaScript, to lower the integration cost for hobbyist and early stage users compared with closed vendor SDKs. Alpha Vantage was launched in March 2017 by Steve Zheng and Olivier Porte, who co-founded it as Harvard Business School MBA classmates; Zheng holds bachelor's and master's degrees in computer science from MIT and had previously worked as a program manager at Microsoft's Silicon Valley office. Reporting from the time describes the idea as a response to the founders' view that, outside expensive terminals such as Bloomberg, there was no affordable or accessible stock data feed for individual investors. The company went through Y Combinator's Summer 2018 batch, raising $120,000 for 7% equity; as of a July 2018 report the company said it had surpassed 100,000 registered users generating more than 300 million API requests per day, a milestone Y Combinator's own company profile attributes in part to a surge of users after Yahoo Finance shut down its market data API in 2017. More recently the company has extended its developer first positioning into agentic AI tooling through the MCP server integration, and runs "Alpha Academy," an educational resource aimed at developers, investors and students learning to work with market data APIs.
