finlight

What makes finlight's query system advanced?

finlight offers sophisticated field-level filtering with operators like ticker:, exchange:, source:, and content:. You can use boolean logic (AND, OR, NOT), inclusion/exclusion operators (+, -), exact phrase matching with quotes, and complex parenthetical grouping. This allows for surgical precision in financial news retrieval.

How do I filter news by specific companies or exchanges?

Use field-specific filters like ticker:AAPL for Apple stock news, exchange:XNAS for NASDAQ-listed companies, or combine them: ticker:TSLA AND exchange:XNAS. You can also use ISIN codes with isin: or OpenFIGI identifiers with openfigi: for precise company targeting.

What's the difference between REST API, WebSocket, and Webhooks?

REST API provides on-demand news data via HTTP requests, perfect for batch processing. WebSocket delivers real-time streaming with sub-second latency for live applications. Webhooks push event-driven notifications to your endpoints automatically when new articles match your criteria.

Can I get real-time sentiment analysis and company extraction?

Yes! Every article includes AI-powered sentiment analysis (positive, negative, neutral) with confidence scores. We also extract mentioned companies with their tickers, exchanges, sectors, and confidence levels. This data is available across all integration methods.

How fast is the data delivery?

REST API responses are typically under 200ms globally. WebSocket streams deliver news in real-time with sub-second latency. Our CDN ensures fast response times worldwide.

What programming languages do you support?

We provide official SDKs for TypeScript/JavaScript (NPM) and Python (PyPI) with full query builder support. You can also use our REST API directly with any language that supports HTTP requests, including cURL for testing.

How do I set up webhooks for automated alerts?

Use our Dashboard Webhook Wizard to configure webhooks visually. Set your endpoint URL, define query filters, and we'll push matching articles to your system automatically. Perfect for automated trading signals and risk monitoring.

Is there a free tier to test the API?

Absolutely! Our free tier includes access to all API features with generous rate limits. Test advanced queries, sentiment analysis, company extraction, and all integration methods. No credit card required to get started.
