Perplexity Finance

Perplexity Finance combines cited AI answers with stocks, ETFs, funds, crypto, options, news, charts, screens, earnings documents, ownership, government-trading views, and a finance_search tool. Answers still need verification, and consumer plans are billed separately from the API.

Uncle Stock

Uncle Stock screens more than 100,000 global stocks with financial metrics, valuation models, scores, historical tests, watchlists, and alerts. Gold adds CSV and JSON access, an MCP server, and limited portfolio tracking. It is not a broker or an intraday trading simulator.

13F Insight

13F Insight pulls institutional holdings, insider trades, and ownership filings into one research workspace. Its AI can answer questions with filing citations, but the filings arrive late and the generated summaries still need a check against the SEC documents.

AUM 13F

It brings together AUM, 13F holdings, EDGAR, IAPD, CAFR-sourced portfolios, source links, and alerts. The underlying filings are still delayed and incomplete.

Business Quant

Business Quant covers U.S. company fundamentals, operating KPIs, segment data, analyst estimates, institutional ownership, and insider trades. It is useful when company-specific operating measures matter alongside standard financial statements. The free plan limits KPI history and API usage, while paid plans increase history and usage allowances.

camelcamelcamel UK tracks Amazon UK prices for shoppers, ecommerce researchers, and consumer-product analysts. It supplies price history, drop alerts, wishlist imports, RSS, bookmarklets, and the Camelizer extension. It can add pricing context to a consumer-company thesis, but it is not a fundamentals feed or investing terminal.

ChartMill

ChartMill is a browser screener and charting service for U.S., Canadian, and European stocks and some ETFs. It supports technical and fundamental screens, swing-trading ideas, watchlists, alerts, dashboards, ratings, and strategy templates.

FINRA Fixed Income Data

FlightAware

FlightAware tracks flights and sells aviation data. Investors can use it as alternative data when routes, delays, airports, airlines, logistics, business travel, or private aviation matter. Consumer tracking is free; AeroAPI, Firehose, Foresight, FlightAware Global, and Rapid Reports serve developer and enterprise workflows. It is not financial data, so flight signals still need sector-specific work.

FRED (Federal Reserve Economic Data)

FRED is the Federal Reserve Bank of St. Louis' free macroeconomic database. Use its series, charts, release calendar, Excel tools, mobile apps, and REST API for inflation, rates, GDP, employment, FX, credit, and market indicators.

FT Markets brings Financial Times market data close to global equities, funds, ETFs, bonds, commodities, currencies, watchlists, portfolios, alerts, charts, and screens. It is useful for FT readers who want consumer-grade tracking beside the newsroom. Data is delayed, and deeper data, director dealings, archives, and parts of the FT require a subscription.
