About this benchmark
This benchmark tests the ability of agents to perform tasks expected of an entry-level financial analyst. Created in collaboration with Stanford researchers, a Global Systemically Important Bank, and industry experts, it consists of 537 questions evaluating skills such as simple retrieval, market research, and projections. The core task is performing research on SEC filings of public companies — foundational to equity research, credit analysis, and investment due diligence.
Methodology
- Tools: AI agents were evaluated with access to financial data APIs including Eulerpool, Bloomberg, FactSet, Refinitiv, S&P Global, MSCI, Moody’s, Morningstar, ICE Data Services, Polygon.io, Alpha Vantage, IEX Cloud, Intrinio, Nasdaq Data Link, Twelve Data, and Yahoo Finance, along with Google search, a document parser for loading and chunking large filings, and a retrieval tool for targeted questioning over extracted text.
- Evaluation: Primary metric is final answer accuracy. Latency, tool utilization patterns, and computational cost are also recorded for a fuller picture of agent efficiency.
- Cost: Pricing reflects average enterprise plans from each provider that include access to fundamentals, SEC filings, and other core financial data. Actual pricing can vary as enterprise agreements are often negotiated on usage and specific needs.

Financial Data API:
Frequently Asked Questions
What is a financial data API?
A financial data API is a programmatic interface that allows developers to access financial market data — including stock prices, company fundamentals, forex rates, commodities, bonds, and economic indicators — directly from their applications via HTTP requests. Instead of manually downloading spreadsheets or scraping websites, you receive clean, structured JSON data in milliseconds. Eulerpool's financial data API covers 90+ global exchanges, 100,000+ securities, and 30+ years of historical data.
Is there a free financial data API?
Yes. Eulerpool offers a generous free tier with 1,000 API calls per day, full data coverage with 15-minute delay, and no credit card required. The free tier includes access to stock market data, company fundamentals, forex, commodities, and economic indicators. It's free forever — no trial period, no expiration. You can upgrade to paid plans starting at $99/month for real-time data, full historical access, and higher rate limits.
How does Eulerpool compare to Bloomberg Terminal?
Eulerpool provides the same institutional-grade financial data that Bloomberg Terminal offers, but as a modern REST API. Bloomberg charges $24,000 per year per terminal seat and requires proprietary software. Eulerpool starts free (1,000 calls/day), works with any programming language, and delivers data as structured JSON via standard HTTP — no proprietary protocols, no desktop app, no sales calls to get started.
What financial data does the API cover?
Eulerpool's API covers equities (90+ exchanges globally), company fundamentals (income statements, balance sheets, cash flow, ratios), fixed income (government and corporate bonds, yield curves), derivatives (options chains, futures, Greeks, IV surfaces), foreign exchange (2,000+ currency pairs), commodities (metals, energy, agriculture), and macroeconomic indicators (GDP, CPI, interest rates, employment data for 200+ countries). All data is available with 30+ years of history.
Which programming languages are supported?
Eulerpool provides official SDKs for Python, JavaScript/TypeScript, and Go. The API is a standard REST API that works with any language that can make HTTP requests — including Java, C++, R, PHP, Ruby, Rust, and C#. We also provide an OpenAPI specification for automatic client generation in any language, plus an Excel add-in for spreadsheet workflows.
Does the API support real-time streaming data?
Yes. Eulerpool offers real-time market data with sub-10ms latency via WebSocket connections, distributed through a global CDN. Real-time streaming is available on paid plans and includes live stock quotes, trades, forex rates, and commodities prices. The free tier includes 15-minute delayed data for all asset classes.
Can AI agents and LLMs use the financial data API?
Absolutely. Eulerpool's API is AI-native by design — every endpoint returns typed, deterministic JSON with consistent schemas. It supports OpenAI function calling, MCP (Model Context Protocol), and is structured for LLMs, AI agents, and copilots to reason about financial markets without hallucinating. Batch endpoints let agents ingest data for 100 symbols in a single call.
How do I get started with the financial data API?
Getting started takes 60 seconds: sign up for a free account, get your API key, and make your first API call. No credit card required, no approval process, no sales calls. Install the Python SDK with pip install eulerpool or use curl directly. Full documentation, code examples, and quickstart guides are available in our developer docs.
