Finance & Markets Toolkit
Ticker data, market fundamentals, and live currency conversion — three Actors for financial research and trading tools.
Ticker data, market fundamentals, and live currency conversion — three Actors for financial research and trading tools.
yfinance, the Python library half the algo-trading community relies on, isn't an official API — it scrapes Yahoo's web endpoints, and Yahoo has been actively clamping down on that traffic specifically, breaking pipelines with silent errors and HTTP 429s. Finviz has no clean API either: scrape it directly and you risk the same "auto-blocked" 403 wall, and the popular wrapper libraries break every time Finviz changes its page structure. Official paid alternatives exist, but they start around $19/month just for reasonable historical depth — real money for what used to be free. This toolkit gives you a fast per-ticker overview (Finviz) and deep fundamentals and quotes (Yahoo Finance) as maintained Actors instead of a library that breaks under you, plus currency conversion for anything crossing borders.
Finviz gives you the fast technical snapshot; Yahoo Finance gives you the deep fundamentals and financials for the same ticker — both maintained as Actors, so a Yahoo layout change or rate-limit change is our problem to fix, not a silent break in your pipeline. Add Wise for currency conversion and you can normalize prices and financials across currencies in the same pipeline — useful the moment you're comparing tickers listed in different countries.
No — neither site offers an official public API. Finviz Ticker Scraper and Yahoo Finance API Scraper reach the same data through Apify instead of an unofficial library like yfinance.
Pay-per-result, no subscription — instead of the ~$19/month official paid tiers some alternatives charge just for reasonable historical depth.
Yes. Run Finviz Ticker Scraper or Yahoo Finance API Scraper alone, and add Wise Currency Converter Helper only when you need cross-currency normalization.
These are maintained Actors, not an unofficial scraping library — when Yahoo or Finviz change their page structure or rate limits, that's fixed at the Actor level, not left for you to patch.
Pay-per-result. No subscription. Start with the one you need.
