Yep is built on the same crawling infrastructure that powers Ahrefs, with an index that spans about 100 billion pages and refreshes roughly 8 billion of them every 24 hours. Rather than selling a general search box, it is positioned as a retrieval layer for AI: the API accepts a query along with filters such as include or exclude domains, categories, location, page type and language, then returns ranked pages and matching passages your model can read directly.
The service is aimed at developers building RAG pipelines, AI agents and research tools who want open-web context in one call instead of scraping and maintaining their own crawler. Results arrive structured, which reduces the post-processing needed before a prompt is constructed.
Pricing is deliberately simple and prepaid: $15 in free credit at signup with no card required, then $0.004 per request for a balanced result set of 1 to 50 results. You define spending limits, and there is no overage billing, so costs stay predictable. It is best understood as an independent search and retrieval API with the heritage of a former consumer search engine rather than a mass-market search destination.
