Yahoo Finance’s free API effectively died in May 2017. What replaced it is a mix of paid data providers, institutional-grade platforms, and all-in-one trading tools. The right replacement depends entirely on what the original API was being used for: raw historical data downloads, backtesting, real-time news, or fundamental research.
This list covers all four use cases. Not every product here competes on the same terms, which is intentional.

1. EOD Historical Data
EOD Historical Data is the strongest direct replacement for the Yahoo Finance API. The coverage is substantial: 700,000,000+ financial data points, 30+ years of historical price data, 20+ years of fundamentals, and 150,000 ticker symbols across 70+ exchanges. ETFs, bonds, mutual funds, cryptocurrencies, and 1,100+ forex pairs are all supported.
Coverage at a glance:
- 150,000 ticker symbols
- 20,000+ ETFs
- 600+ indices
- 1,100+ forex pairs
- Data sourced from Nasdaq Basic API and 14 additional providers
Pricing:
| Plan | Monthly Price | API Requests/Day | Includes |
|---|---|---|---|
| All-World | $19.99 | 100,000 | 60+ exchanges, indexes, forex |
| All-In-One | $49.99 | 100,000 | Everything above + fundamentals, bonds, options, splits/dividends |
Students get an additional 50% off the All-In-One plan by contacting support before purchase. That brings the most comprehensive plan to $24.99 per month, which is genuinely competitive.
The documentation is well-structured. Support runs 7 days a week via email and live chat. Comparable services like Alpha Vantage and Nasdaq Data Link exist, but neither matches this combination of data depth and price.
Pros:
- Most complete coverage at this price point
- API documentation is clear and well-maintained
- Student discount available on request
- Data sourced from Nasdaq Basic API, not scraped aggregates
Cons:
- No free tier (only a 14-day free trial)
- Real-time data is not available on base plans
2. Alpha Vantage
Alpha Vantage is the best starting point for developers who want API access without committing to a paid plan. The free tier allows 5 requests per minute and up to 500 requests per day. That is enough for small projects and testing, not production workloads.
Premium pricing:
| Requests/Minute | Monthly Fee |
|---|---|
| 30 | $29.99 |
| 120 | $49.99 |
| 300 | $99.99 |
| 600 | $149.99 |
| 1,200 | $249 |
Coverage includes intraday and end-of-day historical data, forex, cryptocurrencies, and 50+ technical indicators. Global market coverage is available. No daily limits on premium plans, and cancellation is available at any time.
Two meaningful negatives: there is no official contact information listed on the Alpha Vantage website, which creates an obvious support gap for paying subscribers. The Excel add-on ships as a .exe installer rather than visible source code, which is a genuine inconvenience for anyone who prefers direct API integration over running an executable.
Pros:
- Generous free tier for testing
- Clean API with broad language support
- No daily limits on paid plans
Cons:
- No official contact information on the website
- Excel integration requires .exe installer, not open source code
- Free tier too limited for production use
3. Nasdaq Data Link
Nasdaq Data Link is built for institutional use. The platform consolidates 250+ trusted data sets in a single cloud-based API with integrations for Python, R, and Excel. Over 650,000 traders, institutions, and organizations use the service.
The documentation is strong. The institutional pedigree is genuine.
Pricing is not publicly available for most data sets, which signals that the target customer is not the individual retail developer. For enterprise buyers who need verified, exchange-sourced data at scale, this is one of the more credible options on the market. For a solo developer looking to pull historical prices, EOD Historical Data is more practical and cheaper.
Pros:
- Institutional-grade data provenance
- 250+ data sets via single API
- Strong Excel, R, and Python integrations
Cons:
- Pricing is opaque, custom quotes required
- Not designed for retail or individual developers
- Overkill and likely overpriced for most use cases
4. Intrinio
Intrinio originally served both retail and institutional clients. That positioning has shifted. The current website targets fintech companies, financial institutions, public companies, and startups. Individual pricing is no longer published.
The product itself is technically credible. Intrinio’s proprietary XBRL Standardizer uses machine learning to automate data mapping and claims 99.8% accuracy before human review. For SEC filing data and fundamental datasets, that accuracy claim is meaningful.
The absence of pricing on the website means this is a vendor you negotiate with. Expect enterprise pricing. If the use case is building a fintech application or institutional data pipeline, it is worth a consultation. If the use case is running personal backtests, it is not the right fit.
Pros:
- High-accuracy fundamental data via XBRL Standardizer
- Strong SEC filing and regulatory data
- Suitable for fintech product development
Cons:
- No public pricing
- Individual investors no longer appear to be the target market
- Consultation required before any trial access
5. Trade Ideas
Trade Ideas is a different category of product. It is not a data API. It is a scanning and backtesting platform where the data infrastructure is already built in.
The practical advantage: backtesting a strategy requires no data download, no code, and no data cleaning. Traders define strategies using 500+ filters, set parameters, and push the backtest button. Results come back within seconds. The backtest reports show all trade executions, performance statistics, and optimization opportunities.
Data feeds directly from Nasdaq and NYSE. Brokerage integration is available for E*Trade and Interactive Brokers, enabling automated strategy execution. Scanning capabilities cover gap plays, low float stocks, high relative volume, and a wide range of intraday setups.
This is not a Yahoo Finance API replacement in the technical sense. It is an alternative for traders who were using Yahoo Finance data to build and test systems, and who would rather not manage raw data pipelines at all.
The price reflects the platform’s breadth.
Pricing:
- $228/month
- $2,268/year (two months free)
Pros:
- No code required for backtesting
- Data sourced directly from Nasdaq and NYSE
- 500+ filters for strategy definition
- Brokerage integration for live automation
Cons:
- Expensive relative to pure data providers
- Not suitable for custom algorithmic development outside the platform
- No free tier; trial access requires a sales contact
6. Quantpedia
Quantpedia sits in a different part of the research stack. The platform does not provide raw data. It translates academic finance research into documented, tested trading strategies. The team has read tens of thousands of financial research papers and extracted 600+ quantifiable systems from them.
The strategy library spans equities, bonds, forex, and commodities. Categories include trend following, market timing, stock picking, and asset allocation models. Each strategy includes performance graphs, links to the source academic paper, strategy description, and out-of-sample backtest statistics.
For a trader or fund manager looking to deploy a systematic strategy without starting from scratch on the research, this is a legitimate shortcut. It is not a data tool. It is a research tool.
Pricing:
- $349 for 3 months
- $499 for 12 months
- $999 for 36 months
Pros:
- 600+ strategies with academic backing
- 400+ out-of-sample backtests included
- Saves significant research time for systematic traders
Cons:
- No raw data access
- Strategy library may include outdated academic strategies that no longer perform out-of-sample in current market conditions
- Expensive per month relative to what you get unless actively using the full library
7. Seeking Alpha
Seeking Alpha is the best overall Yahoo Finance replacement for investors who primarily used Yahoo Finance for news, analysis, and fundamental research. With over 20 million monthly visitors, it is already larger than Yahoo Finance in terms of audience.
The free version is functional. The premium version adds Quant Ratings, Wall Street consensus price targets, author ratings, dividend grades, earnings transcripts, peer comparison tools, and brokerage account connectivity for portfolio reporting.
The platform design is clean. Mobile apps for iOS and Android are available. Navigation is straightforward for non-technical users.
One honest point: the quality of analysis on Seeking Alpha varies significantly by author. The Quant Rating system is the more consistent signal. Relying solely on contributor articles for investment decisions carries the same risks as any crowd-sourced content.
Pros:
- Broad coverage of news, analysis, and fundamentals in one place
- Quant Ratings provide a data-driven layer beyond editorial content
- Earnings transcripts are genuinely useful and hard to find free elsewhere
- Free tier is substantive, not a token offering
Cons:
- Contributor article quality is uneven
- Premium pricing is competitive with significantly more specialized tools
- Not suitable for API-style data extraction
8. Benzinga Pro
Benzinga Pro is the most direct competitor to Yahoo Finance for real-time news. The platform is widely cited as one of the fastest retail-facing news services available, with keyword search, custom filters, and sentiment indicators built into the feed.
The feature set extends beyond news: interactive charting, an earnings calendar, audio squawk, a trader chat room, and fundamental data are all included. The platform covers U.S. stocks and options.
The price is the primary obstacle. At approximately $1,997 per year, it is nearly 6x the cost of Yahoo Finance Plus at $350 annually. That premium is defensible if real-time news speed and the audio squawk are essential to the trading workflow. For most investors using Yahoo Finance as a research tool, not a news wire, the cost difference is hard to justify.
Pricing:
- Approximately $1,997/year (promotional pricing is frequently available; verify current rates before subscribing)
Pros:
- One of the fastest retail news feeds available
- Audio squawk included, which most platforms charge extra for
- Keyword filtering and sentiment indicators on the news feed
Cons:
- Significantly more expensive than Yahoo Finance Plus
- U.S. markets only; no international coverage
- Feature set is wide but depth in any single area is limited compared to specialized tools
9. Polygon.io (Now Massive)
Polygon.io rebranded to Massive.com on October 30, 2025. The APIs, pricing structure, and team are unchanged. The name is new. For anyone who has followed this space, it is still the same developer-first market data platform that built its reputation on low-latency U.S. equity data and clean documentation.
The free Basic tier is genuinely usable for testing: all U.S. stock tickers, 2 years of historical data, end-of-day prices, and 5 API calls per minute. That is a meaningful free offering compared to most competitors. Paid plans unlock unlimited API calls, real-time or delayed data depending on tier, and extended historical coverage.
Stocks pricing (monthly, billed monthly):
| Plan | Price | Historical Data | Data Delay | Includes |
|---|---|---|---|---|
| Basic | $0 | 2 years | EOD only | 5 calls/min, reference data, technicals |
| Starter | $29 | 5 years | 15-minute delay | Unlimited calls, WebSocket, snapshots |
| Developer | $79 | 10 years | 15-minute delay | Trades endpoint, file downloads |
| Advanced | $199 | 20+ years | Real-time | Quotes, financials, full tick data |
Annual billing saves 20% across all plans. Options, indices, currencies, and futures are sold as separate subscriptions with their own pricing tiers. The data covers all U.S. exchanges, dark pools, and OTC markets. Latency is documented at under 20ms on premium plans. Access methods include REST, WebSocket, flat-file S3 downloads, and SQL queries.
One thing worth noting before subscribing: Trustpilot reviews for Polygon.io are sparse, only 6 at time of writing, and the negative ones raise specific concerns about options data quality and support responsiveness. That is too small a sample to draw firm conclusions, but it is worth monitoring as the Massive rebrand matures.
The platform is built for developers. Users without coding experience will find limited value here. There is no visual interface for scanning or backtesting; the product is the API.
Pros:
- Free tier includes real data, not just a demo
- Transparent, self-serve pricing with no sales process required
- Access to dark pool and OTC data alongside exchange feeds
- Multiple access methods including SQL and S3 flat files
- 20% student discount available
Cons:
- Options API has drawn criticism for data quality and missing Greeks at lower tiers
- No non-developer interface; requires coding ability
- Trustpilot review volume is very low, making support quality hard to verify independently
- Real-time data requires the $199/month Advanced plan; delayed data only below that
10. Coinranking
Coinranking is the only crypto-focused option on this list. If the original use case for Yahoo Finance was pulling cryptocurrency data, Coinranking is the most purpose-built replacement.
The API covers 10,000+ coins, 200+ exchanges, and 180+ fiat currencies. Data includes live prices, OHLC endpoints (beta), minute-level historical data, circulating supply, social links, block explorer integrations, and sparklines. The infrastructure is built for low latency and high availability with auto-reconnect functionality.
Pricing:
| Plan | Price | API Requests | Notes |
|---|---|---|---|
| Free | $0 | Limited | Basic price data, rate limited |
| Pro | $50/month or $500/year | Unlimited | Full coverage, real-time prices (beta), OHLC, email support |
For crypto developers or traders building applications that require clean, structured coin data with metadata, this is a practical choice. It is not a general-purpose financial data API.
Pros:
- Built specifically for crypto data, not retrofitted
- Rich metadata per coin, not just price
- Unlimited requests on Pro plan
Cons:
- No stock, forex, or traditional asset coverage
- Real-time prices and OHLC endpoints still listed as beta
- $50/month is expensive relative to EOD Historical Data’s all-asset coverage
Bottom Line
Best for raw market data API: EOD Historical Data. The coverage depth at $19.99 to $49.99 per month is the best value in this category. The documentation is clear, support is available 7 days a week, and the data sourcing is transparent.
Best free starting point: Alpha Vantage. The free tier is usable for prototyping. The paid plans are reasonably priced. The missing contact information is a concern, but the API itself is well-documented.
Best for traders who don’t want to manage data: Trade Ideas. The platform removes the entire data infrastructure problem from the equation. Expensive, but it solves a different problem than the others on this list.
Best developer-first API with a free tier: Polygon.io (now Massive). The free Basic plan is real, the pricing is transparent, and the documentation is developer-grade. The $29/month Starter plan is the most accessible entry into unlimited API calls for U.S. equity data.
Best overall Yahoo Finance replacement for investors: Seeking Alpha. Broader coverage, better analysis tools, and a meaningful free tier make it the closest like-for-like upgrade.

FAQ
What killed the Yahoo Finance API?
Yahoo shut down its free historical data API in May 2017. Prior to that, the API had already been altered multiple times, making it unreliable for production use. The download functionality that allowed direct CSV exports of historical prices was removed as part of that shutdown. Historical price data became a commercial product for Yahoo, not a free utility.
Is Yahoo Finance still usable for market data?
Yahoo Finance remains available as a consumer website for news, basic charting, and portfolio tracking. The API is not reliable for systematic data extraction. Screen-scraping workarounds exist in the developer community but are subject to breaking without notice and are not suitable for production applications.
Which Yahoo Finance API alternative has the best historical data depth?
EOD Historical Data offers 30+ years of historical price data and 20+ years of fundamental data across 150,000 tickers. That is the deepest coverage at a consumer-accessible price point. Nasdaq Data Link and Intrinio may have comparable depth for institutional data sets, but pricing is custom.
Is Alpha Vantage free tier sufficient for real use?
500 API requests per day and 5 per minute is sufficient for small personal projects, academic research, or prototyping. It is not sufficient for automated trading systems, broad market scans, or any application requiring real-time updates across multiple symbols simultaneously.
What is the cheapest option for a developer building a stock app?
Alpha Vantage’s free tier costs nothing. If the application outgrows 500 requests per day, the $29.99/month plan is a reasonable next step. For applications requiring fundamentals, splits, dividends, and broader exchange coverage, EOD Historical Data’s $19.99/month All-World plan is more cost-effective than upgrading through Alpha Vantage’s premium tiers.
Which platform is best for backtesting without writing code?
Trade Ideas. The platform has 500+ built-in filters, a visual strategy builder, and a backtest engine that returns results in seconds. No data download or programming knowledge is required. The trade-off is cost ($228/month) and the inability to run custom code outside the platform’s framework.
What happened to Polygon.io?
Polygon.io rebranded to Massive.com on October 30, 2025. It is a name change only. The APIs, endpoints, pricing structure, and team are the same. Existing integrations continue to work without modification. The polygon.io domain remains active during the transition.
