Explore how TerraFin provides AI agents with standardized financial data interfaces, analytical capabilities, and visualization components to accelerate the construction of automated workflows for financial research.
Section 01
TerraFin is a Python toolkit specifically designed for AI agents, providing end-to-end support from data acquisition to visualization. It implements standardized service encapsulation via FastAPI interfaces, aiming to solve key problems of financial AI agents in efficiently acquiring, processing, and analyzing data, and accelerating the construction of automated workflows for financial research.
Section 02
Building financial AI agents faces three major challenges: diverse data sources with varying formats, complex computing needs, and intuitive visualization requirements. Traditional tools are designed for human analysts, emphasizing interactive interfaces, while AI agents need programmatic interfaces, structured outputs, and automated workflows—TerraFin fills this gap.
Section 03
TerraFin designs an abstract data access layer to shield underlying data source differences, supporting free data sources like Yahoo Finance, Alpha Vantage, Quandl, and professional terminals like Bloomberg and Refinitiv. Data sources can be switched via configuration files, with built-in caching and error retry logic, and returned data is uniformly in Pandas DataFrame format.
Section 04
TerraFin integrates rich financial analysis functions: technical analysis (moving averages, MACD, etc.), fundamental analysis (financial ratio calculation), risk management (VaR, volatility, etc.), and portfolio analysis (return rate, efficient frontier, etc.). Calculation results are returned in structured format, supporting step-by-step execution to adapt to AI agent scenarios.
Section 05
TerraFin encapsulates common financial charts (candlestick charts, technical indicator overlay charts, etc.), built on mainstream libraries, and can be saved as images or Base64 strings. The chart styles are professional and clear, supporting custom themes and element configurations, making it easy for AI agents to generate intuitive visual feedback.
Section 06
TerraFin provides FastAPI service encapsulation, exposing functions in the form of REST APIs and supporting HTTP request calls. The APIs follow RESTful principles, include authentication mechanisms and automatic documentation (Swagger UI), and support asynchronous processing of time-consuming tasks to avoid agent blocking and improve efficiency.
Section 07
Typical scenarios for TerraFin include: 1. Automated research report generation (automatically acquiring data, calculating indicators, generating charts and reports); 2. Real-time monitoring and early warning (24/7 market tracking and trigger signal notifications); 3. Quantitative strategy backtesting (simulating trades, evaluating strategy effectiveness, parameter optimization).
Section 08
TerraFin is compatible with the Python data science ecosystem (Pandas, NumPy, etc.), supporting cloud deployment and containerization. Its modular architecture facilitates the expansion of new functions, and community plugins can enrich the ecosystem. It lowers the threshold for building financial intelligent agents and will promote the development of automated financial analysis.

Folkering OS is the world's first AI-native bare-metal operating system, entirely written in Rust no_std without relying on Linux, POSIX, or libc. It can generate commands from scratch, compile them into WASM, and run them in 10 seconds, achieving true self-evolution.
This project explores how to use Large Language Models (LLMs) to detect logical vulnerabilities in Ethereum smart contracts, especially business logic flaws that are difficult for traditional static analysis tools to capture, such as economic manipulation and execution order errors.
This article introduces an open-source project for building modern large language models from scratch. The project evolves from a GPT-2-style basic architecture to a Llama 2/3-style production-level implementation, covering complete tutorial implementations of key technologies such as RMSNorm, RoPE, SwiGLU, GQA, and MoE.
