Top 10 picks

10 picks

1
Fiscal.ai
Fiscal.ai is an AI-assisted public-company research terminal and financial data API platform for investors, analysts, developers, and AI-agent builders. It combines global fundamentals, segments and KPIs, transcripts, filings, estimates, dashboards, screeners, valuation workflows, AI Copilot, REST APIs, webhooks, and MCP access.

2
FinancialReports.eu
FinancialReports.eu is a public-company filings database, filings API, and hosted MCP server for analysts, AI-agent builders, and data teams that need fast document ingestion, Markdown extraction, watchlist alerts, webhooks, and filing Q&A across global markets. It is strongest when the workflow starts with filings rather than price charts: company documents, insider trades, IPO references, filing feeds, and programmatic document access are the center of the product. Free access is mainly for testing; Analyst or Enterprise is needed for serious API, MCP, AI chat, and production workflows.

EODHD
EODHD is a market-data API provider for developers, quants, and analysts who need REST, WebSocket, spreadsheet, and AI-agent access to historical prices, fundamentals, calendars, news, sentiment, options, forex, crypto, and other financial datasets. It is strongest for API-first data workflows, but free usage is tiny, commercial licensing is separate, and some datasets require add-ons or marketplace plans.

Financial Modeling Prep (FMP)
Financial Modeling Prep (FMP) is a market-data API and spreadsheet-data provider for developers, analysts, quants, and product builders who need equities, ETFs, funds, FX, crypto, commodities, macro, ESG, ownership, news, calendars, transcripts, and fundamentals from one vendor. It is strongest when you want REST and WebSocket access plus Excel and Google Sheets add-ins at a lower entry price than enterprise terminals. The main buying questions are plan limits, geography, history depth, and dataset access: the free Basic tier is a limited EOD sandbox, while real-time, global, transcript, 13F, holdings, intraday, and bulk workflows require paid tiers.

Alpha Vantage
Alpha Vantage is an API-first financial data provider for developers, students, quants, and analysts who need a simple API key for stock, ETF, mutual fund, FX, crypto, options, commodities, fundamentals, news, sentiment, and macroeconomic datasets. It is strongest for learning, prototypes, spreadsheets, and personal API workflows, but the free quota is small, premium endpoints require membership, and commercial use needs separate licensing.

Quartr
Quartr is a qualitative public-market research platform for earnings calls, real-time transcripts, filings, reports, slide decks, analyst estimates, AI chat, and investor-relations data. The mobile app is useful for free earnings-call and transcript access, while Quartr Pro and Quartr API serve professional research, MCP, webhook, and data-integration workflows.

Wall St. Rank
Wall St. Rank is a fund- and analyst-consensus research product for 13F manager portfolios, fund trends, analyst ratings, price targets, news sentiment, indexes, and API-accessible data. It is useful for U.S.-listed ownership and analyst research, but 13F data is delayed, API/bulk access is contact-sales, and the product is not live fund positioning or trade execution.
List votes
Pricing: From $20/moPlatforms: Web, API
8
Financial Datasets
Financial Datasets is a developer-focused financial data API and official MCP server for teams building AI agents, stock screeners, portfolio tools, research apps, and quantitative workflows. It is strongest when you need simple programmatic access to U.S. equity fundamentals, prices, SEC filings, insider trades, institutional ownership, news, crypto prices, and screener endpoints without assembling many separate data vendors. The tradeoff is scope and licensing: coverage is centered on U.S. public companies, there is no permanent free tier, and redistribution is gated to Scale or Enterprise.

9
Trading Economics
Trading Economics is a macro and markets data platform for browsing economic indicators, calendars, forecasts, market data, company financials, news, ratings, and corporate events, with paid REST API, WebSocket, spreadsheet, BI, and AI-assistant integrations. It is strongest for developers, analysts, and teams building dashboards, alerts, research apps, and macro data pipelines from one source. Guest credentials provide limited sample access, while Standard, Professional, and Enterprise plans govern real API use, streaming, rate limits, row limits, and commercial rights. It is data infrastructure, not a broker or investment-advice service.

Benzinga
Benzinga is a market-news, trading-tools, and financial-data platform for active traders, investors, developers, and data buyers who need fast news, alerts, scanners, calendars, squawk, options activity, analyst actions, filings, transcripts, and APIs. It is strongest for event-driven monitoring and real-time workflow around Benzinga Pro or licensed feeds, but the useful trading features are paid, tiered, or add-on based, and the product is not a long-term portfolio accounting system.

Börsdata
Börsdata is a Nordic-first equity analytics, screening, and data platform for investors who want long-history fundamentals, thousands of ratios, strategy screens, ownership data, insider and short-selling context, technical charts, reports, watchlists, calendars, and API or spreadsheet access. It is strongest for Nordic stock research, while global coverage, holdings data, Excel/Sheets workflows, and REST API access depend on paid tiers and professional users are routed to Enterprise.

Calcbench
Calcbench is a professional SEC filing, XBRL, financial statement, disclosure, and Excel research platform for analysts who need traceable as-filed numbers, standardized accounting metrics, footnotes, redlines, proxy data, compensation data, M&A details, and API access. It is strongest for accounting-heavy U.S. equity research and data workflows, but meaningful access is priced for professional users and API access is sold separately from standard subscriptions.

Estimize
Estimize is a crowdsourced earnings and macro-estimates platform for investors and data teams that want alternative expectations data before company reports and economic releases. Use it for EPS, revenue, and macro forecast context, not for broad portfolio management or trading execution.

FinancialData.Net
FinancialData.Net is an API-first financial data platform for developers, analysts, spreadsheet users, and AI-agent builders who want broad market data, fundamentals, ownership, options, funds, ESG, calendars, news, Excel access, and MCP connectivity from one provider. It is strongest when breadth matters: stocks, ETFs, mutual funds, options, futures, crypto, forex, commodities, OTC securities, indices, filings-related datasets, and institutional/insider activity can sit behind one REST API. Serious use is paid, and compliance/security claims should be verified directly because the local profile does not include public audit reports.

15
Intrinio
Intrinio is a financial data infrastructure vendor for developers, data teams, and AI builders who need licensed market data, fundamentals, options, ETF, mutual-fund, analyst, dividend, split, and company-news datasets through APIs, WebSockets, files, Snowflake, S3, and selected FTP workflows. It is strongest when the buyer needs production data delivery and usage rights rather than an end-user research app. Pricing, entitlements, real-time access, redistribution, and delivery methods vary by dataset and plan, so it should be evaluated as a vendor contract rather than a simple retail subscription.

Marketstack
Marketstack is an APILayer REST market-data API for developers who need stock prices, end-of-day history, intraday bars, corporate actions, reference data, ETF holdings, bond yields, commodities, analyst ratings, and SEC EDGAR company datasets through JSON endpoints. It is useful for prototypes and products that need a simple stock market API with a free tier and clear paid plans. It is not a charting app, broker, portfolio tracker, screener UI, or unlimited institutional data license.

Tiingo
Tiingo is an API-first market data provider for developers, quants, and small teams that need transparent flat-rate access to prices, fundamentals, corporate actions, news, forex, and crypto data. It is strongest when the user wants JSON, CSV, REST, WebSocket, Python, and AmiBroker-friendly data access rather than a consumer portfolio app. Free and paid plans differ by endpoint access, usage limits, history, and commercial rights. Tiingo is not a broker, portfolio tracker, research terminal, or blanket redistribution license; users need the right plan for business and commercial use.

Visible Alpha
Visible Alpha, now part of S&P Global Market Intelligence, is an enterprise consensus and model-derived data platform built from full sell-side analyst models. It is useful for line-item estimates, segment/KPI consensus, Excel workflows, and data delivery, but it is not a retail all-in-one terminal, broker, or self-serve low-cost data product.

SEC API (sec-api.io)
SEC API is a commercial SEC/EDGAR API suite for developers, quants, compliance teams, and AI products that need fast filing search, real-time feeds, XBRL-to-JSON conversion, section extraction, insider filings, 13F data, and other structured regulatory datasets. It is strongest when you want production-ready normalized SEC data instead of building your own EDGAR ingestion stack, but the free tier is only a small starter allowance and redistribution requires enterprise terms.

GuruFocus
GuruFocus is a value-investing research platform for investors who want global fundamentals, valuation tools, GF Score, GF Value, screeners, backtesting, guru and institutional holdings, insider trades, portfolio tracking, spreadsheet add-ins, and data/API access. It is strongest for fundamental and value-oriented research rather than brokerage execution.

Best Financial Data APIs FAQ

What belongs on this financial data APIs page?

This page is for API-first financial data products with endpoints, documentation, SDKs, quotas, rate limits, exports, licensing, or data delivery workflows for developers and data teams.

How is this different from stock analysis software?

Stock analysis software is investor-facing. Financial data APIs are developer-facing or data-team-facing products used to build apps, models, dashboards, databases, and internal research systems.

Are filing and transcript APIs included?

Yes, when API access is a primary workflow. Interactive filing search and transcript research products still fit better on their dedicated SEC filing or earnings call transcript pages.

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.
