Finnhub
finnhub.io
Stock, forex and crypto API with fundamentals, estimates and alternative data like congressional trades, a 60-calls-a-minute free tier and paid data packs.
What it is
Finnhub is a REST and websocket API that combines market data with company data. Besides real-time US stock prices, forex and crypto, it offers financial statements, analyst estimates and price targets, earnings calendars, company news, ETF and mutual fund holdings, and alternative data including congressional trading, Senate lobbying, patents, ESG scores and social sentiment. Official client libraries exist for Python, Go, JavaScript, Ruby, Kotlin and PHP, and there is an MCP server for AI assistants.
The free plan is generous for prototyping: 60 calls a minute, US coverage, a websocket for 50 symbols, a year of company news, a month of earnings calendar and the last four quarters of earnings surprises. Paid access is sold as separate packs rather than one ladder. Market data runs from $49.99 to $199.99 a month and mainly adds history depth, call limits and websocket symbols; fundamentals cost $50 or $200 a month per market; estimates, ETFs and indices, forex, crypto and bonds each have their own pricing.
Read the billing terms before subscribing: most packs are billed quarterly or annually rather than monthly, and the listed plans carry a personal-use license, with startups and enterprises pointed to a separate page. Every plan also has a hard cap of 30 calls a second. Options data does not appear in any of the pricing tables.
