Finlight is a real-time financial intelligence API for developers, designed to provide applications with real-time financial news, AI-driven sentiment analysis, and enterprise-grade reliability.
Purpose
Finlight primarily serves scenarios such as fintech, quantitative trading, risk management, and research analysis. Through this API, developers can obtain real-time financial news and use capabilities such as AI sentiment analysis and company entity extraction to build applications for trading signals, risk alerts, market analysis, and more.
Main Capabilities
- Real-time financial news: Covers global exchanges and supports precise filtering by fields such as stock ticker, exchange, and source.
- AI sentiment analysis: Performs sentiment tendency analysis on news articles and can be used in conjunction with trading signals.
- Company entity extraction: Automatically identifies related companies from news content.
- Advanced query engine: Supports Boolean logic (AND, OR, NOT), inclusion/exclusion operators (+, -), exact phrase matching with quotation marks, field-level filtering (such as ticker:, exchange:, source:, content:), and parenthetical grouping to control precedence.
- Three integration methods:
- REST API: Suitable for on-demand data retrieval, web applications, and batch processing.
- WebSocket: Real-time data streaming with sub-second latency, suitable for real-time trading applications.
- Webhook: Event-driven notifications pushed to specified endpoints, suitable for automated trading and alerts.
- Multilingual SDKs: Provides eight official client libraries: TypeScript, Python, Go, .NET, Java/Kotlin, PHP, Ruby, and Rust.
- AI assistant integration: Connects Claude, ChatGPT, and other AI assistants through MCP (Model Context Protocol).
- Automation platform integration: Supports connection with visual automation platforms such as Zapier, providing no-code workflows, real-time triggers, and prebuilt templates, and can connect to 1000+ applications such as Slack, Discord, email, and databases.
How to Use
Developers can integrate quickly through the official SDK, for example npm install finlight-client or pip install finlight-client, or directly use cURL to call the REST API. When querying, use the query engine to build complex conditions, for example using + to include terms,- to exclude terms, quotation marks to match exact phrases, parentheses for grouping, and so on. WebSocket is used for real-time streaming, and Webhook is used for event push.
Applicable Scenarios
- High-frequency trading: Use real-time news signals and sentiment data to execute trades at the millisecond level.
- Risk management: Monitor portfolio risk, track regulatory keywords, and automatically send risk alerts.
- Global market analysis: Track international market and political events that affect investments.
- Research and analysis: Build research platforms containing historical and real-time data for multi-ticker analysis.
- Economic and macro news: Track headlines on the Federal Reserve, CPI, inflation, and interest rate decisions, delivered via REST, WebSocket, or Webhook.
Limitations
Details such as the free tier, specific pricing, specific values for data latency, and support scope are not explicitly provided in the official materials. Some features (such as free account requirements) are mentioned in the interactive demo, but specific limitations are not currently provided.
