Alpha Vantage
Comprehensive stock, forex, and crypto API with free tier and NASDAQ-licensed real-time data at low price points
Viable option — review the tradeoffs
You need affordable access to stock, forex, and crypto data including 50+ technical indicators without building your own data pipeline.
Free tier vanishes after 25 calls/day (5/min)—fine for prototyping, forces premium ($50+/mo) for production; data reliable but cache locally to dodge throttling.
You want ready-to-use technical indicators for trading signals or backtesting without computing them yourself.
Excellent coverage and accuracy; compact mode (100 points) saves calls on free tier; full history needs premium.
Free tier too restrictive
Only 25 requests/day (down from 500 historically) with 5/min rate—exhausted instantly for multi-asset agents; real-time US data premium-only.
Rate limits kill live agents
Free: 25/day total, 5/min; premium scales to 1200/min but IP throttling reported on shared hosts—schedule fetches post-market, cache religiously, or upgrade early.
Alpha Vantage dominates indicators + AI integration; Polygon wins latency + free tier generosity.
Need 50+ pre-built TA indicators or official LLM server.
High-frequency needs or better free tier (5/min vs 25/day).
