EXA_FIND_SIMILAR

Find similar (Deprecated)

DEPRECATED: /findSimilar is a legacy endpoint and is no longer recommended for new integrations. Migrate to EXA_SEARCH with type='deep-lite' or 'deep' passing a URL-shaped query, optionally with the nested `contents` object for enrichment. Existing calls continue to work for now. Finds web pages semantically similar to a given URL using embeddings-based search, optionally retrieving full text, highlights, or summaries for results.
