xfinlink
Xfinlink is a financial data API for US equities. It is built for users who want research-grade market data and a way to spend less time cleaning data and more time researching. The service centers on historical and point-in-time financial data, with support for price history, fundamentals, metrics, insider transactions, and index membership.
Its coverage includes 81M+ daily prices, 47K+ total entities, 17K+ delisted entities, and 50+ years of history. The API exposes OHLCV, returns, splits, and dividends for price history; standardized filing statements and segments for fundamentals; ratios, margins, growth, and valuation data for metrics; and Form 4 insider transactions plus point-in-time index membership. It also includes entity resolution for recycled tickers, survivorship-bias-free history, split-adjusted prices, GICS sector and industry tagging, industry-aware fields, standardized columns, tidy DataFrames with parsed dates and proper dtypes, and built-in scores such as Altman Z, Piotroski F, and Beneish M alongside 100+ valuation and profitability ratios. Fundamentals are available both as originally reported and as restated, and returns are available on a total-return basis with dividends or as split-adjusted price-only return.
Access is available through Python, REST, and MCP. The site shows a Python client, an MCP server, and installation via pip. It also says that most API requests require an API key, with free accounts available to get one, while search and resolve allow restricted unauthenticated calls. The documentation names seven endpoints: prices, fundamentals, metrics, insiders, resolve, index, and search. Example usage is shown for research pipelines, trading systems, weekend projects, factor backtests, survivorship-bias studies, insider-signal research, and runnable notebooks. The page also says the data can be connected to any LLM agent over MCP so the agent uses the same clean data.
The product appears under the name Xfinlink and is accompanied by Docs, Pricing, Blog, and Contact links, but no license terms are stated in the supplied text.
