Diffbot vs Aylien News API: overview

Diffbot

Diffbot combines automatic web page extraction (Article API, Product API, Discussion API) with a continuously-updated knowledge graph of 10 billion+ entities including companies, people, products, and events. Its Knowledge Graph Search API queries this structured dataset using natural language rather than keywords, enabling precise entity-level retrieval beyond what SERP APIs provide. Diffbot was founded in 2010 by Mike Tung at Stanford University and is headquartered in Menlo Park, California. It uses computer vision and machine learning to extract structured data from any web page without custom selectors. Clients include Snapchat, DuckDuckGo, Cisco, and Goldman Sachs (per company website; independently unverifiable).

Aylien News API

Aylien News API (now part of Quantexa, acquired 2024) indexes 80,000+ news sources globally and enriches every article with Natural Language Processing: named entity recognition, sentiment analysis, IAB topic classification, and author extraction. This pre-processed enrichment layer separates it from raw news aggregators — callers receive structured signals rather than raw article text. The API covers 50+ languages and enables filtering by entity, sentiment, topic, country, source, and publication time. Aylien was founded in 2012 and is headquartered in Dublin, Ireland. Following the Quantexa acquisition in 2024, the News API product continues to operate under the Aylien brand (per company website; independently unverifiable).

+ Natural language knowledge graph search enables entity queries not achievable with keyword-based SERP APIs
+ Computer vision extraction adapts to layout changes automatically — no maintenance when target sites redesign
+ Clients include DuckDuckGo and Goldman Sachs (per company website; independently unverifiable)
- $299/month minimum subscription is high for low-query-volume use cases — no pay-as-you-go tier documented
- Knowledge graph depth varies: company and person data is comprehensive; niche topics and non-English entities may be sparse
- Not a real-time SERP API — knowledge graph reflects Diffbot's crawler cadence; breaking news may lag by hours
- GraphQL interface for knowledge graph queries has a steeper learning curve than standard REST/JSON SERP APIs

+ Named entity linking resolves entities to standard identifiers enabling cross-article tracking and aggregation
- Acquired by Quantexa in 2024 — product roadmap and long-term API support subject to Quantexa's strategy (per company website; independently unverifiable)
- Pricing not publicly disclosed — requires enterprise sales contact, making cost comparison difficult
