xfinlink provides a financial data API focused on US equities, offering access to research-grade datasets for developers, researchers, and analysts. The platform delivers comprehensive historical and fundamental data, aiming to reduce time spent on data cleaning and enable more efficient research workflows. Users can access the API through a Python client, REST interface, or MCP server, with installation available via pip and authentication managed by API keys.
The service covers over 81 million daily prices, 47,000 entities, and includes data for more than 17,000 delisted companies, spanning over 50 years of history. Its endpoints offer access to price histories (including OHLCV, returns, splits, and dividends), standardized financial statements, pre-computed financial metrics, insider transactions (Form 4), and point-in-time index membership. The API also supports entity resolution, ensuring that recycled tickers are mapped correctly and that historical data remains accurate and survivorship-bias free. Every entity is tagged to its GICS sector and industry, and data fields are industry-aware, providing relevant information for banks, REITs, and other sectors. Columns are standardized across companies, with consistent field names and units, and data is formatted for direct use in pandas, supporting tidy DataFrames with parsed dates and proper data types.
xfinlink is designed to integrate seamlessly into research pipelines, trading systems, or smaller projects, with quick setup and straightforward queries. It offers both authenticated and limited unauthenticated access, with a free account providing an API key for normal usage limits and full data detail. The platform also features built-in financial scores such as Altman Z, Piotroski F, Beneish M, and over 100 valuation and profitability ratios. Both originally reported and restated fundamentals are available, and the data supports both total returns (with dividends) and price-only returns (split-adjusted). AI-native integration is possible via MCP, allowing LLM agents to access the same standardized data.
The tool positions itself as a research-grade solution for accessing and analyzing US equities data, supporting a wide range of financial research, backtesting, and analytics use cases.
