Marketstack Review, Pricing, and Features
Marketstack is an APILayer REST market-data API for developers who need stock prices, end-of-day history, intraday bars, corporate actions, reference data, ETF holdings, bond yields, commodities, analyst ratings, and SEC EDGAR company datasets through JSON endpoints. It is useful for prototypes and products that need a simple stock market API with a free tier and clear paid plans. It is not a charting app, broker, portfolio tracker, screener UI, or unlimited institutional data license.

Curation & Accuracy
This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).
Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
