We ranked 14 free stock APIs on limits, delay, history and terms; Tradier ranks first, we rank sixth. - [Max Nowak](/about/), Operations Manager - Last updated September 26, 2026 A yfinance alternative is worth switching to once the Python library’s rate limits, IP blocks or breaking changes cost you more time than a paid API would. yfinance scrapes Yahoo Finance’s own pages, and Yahoo’s terms forbid that kind of automated collection. We ranked 14 free stock APIs, official and documented, that replace it. We are one of the 14, so we have a stake here. A search for a yahoo finance api alternative usually wants the same three things: a documented endpoint, a rate limit set on purpose rather than discovered by accident, and terms that allow a real app. We scored our own free plan with the same rubric as the rest, and it lost points on freshness. ## Which free stock API is the best yfinance alternative? The [free stock API](/alternatives/free-stock-api/) ranking scores all 15, Yahoo Finance included; this table leaves it out. | Rank | Provider | Score | Best for | Paid plans from | | --- | --- | --- | --- | --- | | 1 | Tradier | 7.1 | Free real-time stocks and options | $10/mo | | 2 | Alpaca | 6.5 | Real-time free data via a brokerage | $99/mo | | 4 | Tiingo | 6.4 | Generous free quota with deep history | $25/mo | | 5 | Google Finance | 5.8 | Unlimited free quotes in Sheets | Not published | | 6 | Market Data | 5.6 | Free forever, no card needed | $12/mo | | 7 | EODHD | 5.4 | Small free quota, best reviews | $16.58/mo | | 7 | ThetaData | 5.4 | Free EOD options and stock snapshots | $40/mo | | 9 | Financial Modeling Prep | 5.1 | Free fundamentals and filings access | $22/mo | | 10 | Massive | 4.8 | Free access to a broad multi-asset API | $23.20/mo | | 11 | Twelve Data | 4.6 | Free trial-symbol access, generous quota | $66/mo | | 12 | Finnhub | 4.4 | Broad data, undocumented free limit | $49.99/mo | | 13 | Nasdaq Data Link | 4.2 | Free key to a broad marketplace | $9/mo | | 14 | Alpha Vantage | 3.8 | Free access to global symbols | $41.58/mo | | 15 | Marketstack | 3.5 | Cheap international EOD, small quota | $8.99/mo | The four most relevant alternatives, with Yahoo Finance’s own free tier for comparison: | Feature | Tradier | Alpaca | Tiingo | Yahoo Finance | Market Data | | --- | --- | --- | --- | --- | --- | | Free tier | Yes, $0 min., real-time data included 1 | Yes, IEX equities + indicative options 2 | 1,000 req/day, DOW 30 fundamentals 3 | Yes, real-time US quotes, no card 4 | 100 credits/day, 1yr history, delayed | | Real-time US stocks | Yes, free with any account 5 | Free: IEX only.

In August 2026 we onboarded an options research service that was explicitly replacing Yahoo Finance as its backend price source, feeding a scanner from our API instead of scraping one. A real-time price starts on the Starter plan at $12 a month billed annually; try our [stock market API](/api/) free plan first. ## Is yfinance still free to use in 2026? Yes, but “free” only covers the price. Yahoo’s terms bar automated collection of its data, and [yfinance’s own GitHub issues](https://github.com/ranaroussi/yfinance/issues/2422) record HTTP 429 errors and multi-day IP blocks through 2026, with no published threshold for either. ## Is yfinance legal for a commercial app? No. Yahoo’s [terms of service](https://legal.yahoo.com/us/en/yahoo/terms/otos/index.html) forbid using its content for any commercial purpose and bar building a product that substitutes for its own service. Our [Yahoo Finance API](/alternatives/yahoo-finance-api/) guide covers the scraping workaround and where it breaks. ## Which yfinance alternative fits which need? For free real-time stock data, Alpaca, if a brokerage account is acceptable. For the longest free history, Tiingo. For options alongside stocks, ours or Tradier’s, since the options chains yfinance reads from Yahoo are always 15 minutes delayed. We’ve told developers who assumed a Yahoo-style ticker meant global coverage that we cover US markets only, every year from 2022 through 2026, so anyone trading outside the US should look elsewhere on this list. Our broader [best stock API](/alternatives/best-stock-api/) ranking scores the paid tier here against 16 others, and the [ranking of financial data providers](/alternatives/financial-data-providers/) adds commercial pricing to the comparison. ## Is a product that shows only derived scores still commercial? Yes, if other people see it. In August 2026 a startup building a paid options research service asked to use our API only on its servers, as a replacement for Yahoo Finance. Its customers would only ever see its own scanner scores and option picks, never our prices. We still classed it as commercial use, because the output served a paid product to other people, and we referred it to our partner Intrinio. The same rule separates it from the personal case: a subscriber who feeds our data into an AI assistant for his own trading stays on a personal plan. ## What does a price mismatch with GOOGLEFINANCE usually mean? In our support history, a different listing or a different adjustment, not bad data. In September 2025 a Sheets user reported a symbol more than 10% away from GOOGLEFINANCE, stamped 17:30 instead of the 4 p.m. close. GOOGLEFINANCE was returning a Stockholm listing with the same ticker, and the customer confirmed it. His second symbol differed because we had adjusted its history for a January 2025 spin-off and the free source had not. Our STOCKDATA formula takes an unadjusted option when you want prices as traded. ## When should you stick with yfinance? yfinance still makes sense for a class assignment, a weekend backtest, or a script that runs a few times a day and can absorb an occasional block. It needs no signup and no card. Once a rate limit costs you data on a day that matters, or the code has to run in production, an API built for that is the safer bet. If yfinance is one of several providers on your list, our pages on [IEX Cloud alternatives](/alternatives/iex-cloud-alternatives/) and [Alpha Vantage alternatives](/alternatives/alpha-vantage-alternatives/) use the same rankings.
