  title: Payerset Data Lake API
  description: >-
    The Payerset Data Lake API provides programmatic access to U.S. healthcare
    price transparency data parsed from payer Transparency in Coverage (TiC)
    machine-readable files and hospital price transparency MRFs, enriched with
    provider, payer, and billing-code reference metadata. Endpoints support
    payer/provider negotiated rate lookups, NPI and TIN provider mapping,
    billing-code classification, and hospital MRF discovery. Authentication is
    via an API key supplied in the x-api-key header.
