Free web search API for LLM agents, RAG pipelines and AI chatbots
Issue search queries and receive titles, source links and snippets with no per-request charges on the free plan.
Request full page content instead of snippets and cap it per result with a max_characters setting.
Call the same search engine from an HTTP API, an MCP endpoint for agents, or a skill for coding assistants.
Restrict results with includeDomains and excludeDomains, plus freshness presets, single dates or inclusive date ranges.
Independent web search and agent grounding API built on the Ahrefs index
Submit a query and receive ranked pages, not just links, from an independent index so you are not dependent on a single commercial search provider.
Each result includes the passages that answer the query, so a language model can read relevant context without parsing entire pages.
A single endpoint call returns open-web context for your model, designed for RAG and agent grounding workflows.
Roughly 100 billion pages crawled since 2010 with around 8 billion refreshed every 24 hours, which keeps results reasonably current.
