Answer
First-line drugs include endocrine therapy (tamoxifen, aromatase inhibitors, or fulvestrant) for HR+/HER2− cases, and HER2-targeted therapies such as trastuzumab for HER2+ cases.
Evidence with coordinates
Every answer cites canonical source URIs — fixed positions in the corpus you can return to and verify. Retrieved text is evidence for review, not proof that a claim is correct.
Citation-grounded agents →
Give an agent compact search results, canonical source URIs, bounded full text, and document-level passage search.
Systematic reviews →
Build a traceable discovery and screening pipeline across scholarly metadata, abstracts, and available full text.
Patent prior-art search →
Search patents alongside papers and technical reference works, then preserve identifiers for expert review.
Build on the corpus
The same retrieval through three instruments: the web app to prototype, REST to automate, MCP for agents. One key, per-request pricing.
Search API
Ground your agents and models with the same retrieval over REST or MCP.
