Graph, vector and text retrieval for AI agents on your Postgres
Query graph, vector, full-text and hybrid retrieval through one consistent interface instead of stitching multiple systems together.
The open-source pgGraph engine follows relationships across your records, enabling multi-hop and shortest-path retrieval without moving data.
Semantic search over embeddings combines with sparse and full-text matching so queries that mix meaning and exact terms still work.
A dashboard playground, CLI for imports and configuration, and a typed Python SDK make it straightforward to prototype and then ship.
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.
