About Search for Agents

Search for Agents is a field guide to the systems an agent uses to find and check information. Start with how agent search works, then use Lay of the Land to find products and projects at each stage.

We cover three connected areas: web discovery, specialist sources such as filings and scientific literature, and the infrastructure used to acquire, index, retrieve, rerank, and evaluate information. A search API, crawler, vector database, embedding model, and reranker solve different problems. Our guides explain where each fits and what to test before choosing one.

Search for Agents is published by Valyu, which is also listed in the provider directory. The site has its own editorial identity, but readers should know that connection when assessing our coverage. Directory entries link to primary product material and describe documented capabilities. They are not hands-on reviews or performance rankings. Our methodology explains the selection and comparison rules, including what an empty coverage mark means.
