Marketstack Review, Pricing, and Features
APILayer’s Marketstack provides a REST/JSON market data API (V2) for end-of-day and intraday stock prices, corporate actions, and reference data (tickers/exchanges). Professional+ adds real-time intraday update intervals (<15min) and additional endpoints (e.g., real-time stock prices and commodities); Business+ adds analyst ratings/price-target data and SEC EDGAR company datasets. V1 endpoints were scheduled for deprecation after 2025-06-30.

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 Pricing, features, and availability may be incomplete or out of date.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.
