Citation Network Analysis
Goes beyond keyword matching — uses the citation graph to find papers that are structurally related through shared citations.
Similarity Scoring
Each result includes a similarity score, PageRank importance, and graph distance from the seed paper.
Graph Edges
Enable includeEdges to get citing/cited_by relationships between results for building interactive citation graphs.
Credit Costs
Simple, predictable pricing
per request
Each similar papers request costs 3 credits regardless of the number of results returned or whether graph edges are included.
