Services: Search, Data and Content Feeds

The index, the taxonomy and the enrichment pipeline behind the 4Search network are available on their own. Five services, all drawn from the same corpus and the same classification work.

Talk to us

Custom Search API & Search Engines

Build a domain-specific search engine on hybrid retrieval -- BM25, dense vectors and rerankers -- with taxonomy and ontology filtering on top.

Enriched Data

Every page we index becomes a structured, machine-readable object carrying the quality metadata that AI training depends on.

News & Content Feeds

Micro-tailored feeds drawn from a taxonomy of more than 20,000 topics, filtered by topic, entity, region or source.

Webpage Conversion

Turn any webpage into an Enriched Document on the same schema our data services use -- for training, search, analytics and content operations.

Topic & Niche Advertising

Reach focused-intent audiences at the topic or niche level across the network, on flat monthly pricing with unlimited impressions.

Not sure which one fits?

Tell us what you are building and what shape the output needs to take. Most engagements start as either a search index or a feed, and the enrichment layer is shared between them either way.
