Ask a question in plain English. Get healthcare providers with full provenance.

Search runs against the Fonteum healthcare-provider data graph. Each result is ranked by semantic similarity to your query and carries an 8-tuple provenance trace — source, dataset, snapshot, methodology, last-checked, confidence, availability — so a citation is always one click away.

• Your query is parsed by an LLM (Anthropic Haiku) into structured filters — vertical, state, county, exclusion flags. The raw query also goes through an embedding model (OpenAI text-embedding-3-small) to rank by semantic similarity.
• Results come from the Fonteum healthcare-provider data graph — ~26K confirmed providers across the published methodology. Every result is one Postgres row, ranked by cosine distance, hydrated from the underlying CMS NPPES snapshot.
• For the API contract, query examples, and code samples see /docs/search.
• Search shares the same 8-tuple provenance contract as the audit-pack and the MCP server. Tooling that consumes one consumes all three without translation.
