Finlight

Finlight is a real-time financial news API for developers, startups, and enterprises building trading platforms, alerting systems, dashboards, and research tools that need fast, precise news retrieval.

Key capabilities include:

• Three delivery methods: REST endpoints for on-demand and batch retrieval, WebSocket streaming for newly published articles matching live queries, and webhooks for event-driven notifications.
• Advanced query language with field operators such as ticker:, exchange:, source:, and content: plus boolean logic (AND, OR, NOT), inclusion/exclusion (+, -), exact phrases, and parenthetical grouping.
• AI-driven sentiment analysis (by tier) with sentiment labels and scoring, confidence metrics, and sentiment-based trading signals.
• Rich article data (by tier) including headlines, summaries, full text, and metadata such as categories, language, countries, and extracted company entities.

Pricing: Freemium, Launchpad ($0/month, 5k requests, 12h delay), Pro Light ($29/month, 10k requests, real-time access), Pro Standard $99/month (50k requests) and Pro Scale $249/month (150k requests) tiers with additional features like sentiment analysis and priority support.

What makes it notable is its combination of sub-second delivery options (REST, WebSocket, webhooks) with field-level, boolean query precision, built specifically for financial-news workflows rather than bundled market data like quotes or fundamentals.
