Kingy AI Take
Perplexity introduced Sonar Pro API access for developers building search-grounded AI products with citations and web retrieval (perplexity.ai). Live retrieval is a building block many agents and research apps need, and this packages Perplexity's search behind a developer surface. Teams still need to evaluate latency, cost, source quality, and citation reliability in production workflows before committing.
Who it is for
Developers and companies that need web-grounded answers, search retrieval, and citations inside their own applications.
Traction notes
Search-grounded API access is a key category for AI launch tracking because many agents and research apps need live retrieval.
