title: Serif Health Pricing API
description: >-
REST API for Serif Health's normalized healthcare price-transparency data.
Query payer-negotiated reimbursement rates and percentile rate distributions
for an individual procedure code (CPT/DRG), filtered by region, tier, site of
service, payer, and weighting. Rates are derived from federally mandated
machine-readable files (MRFs) published by payers and hospitals.
Only the rates and distributions endpoints are documented here from public
Serif Health materials. Find Care, Provider Directory, and dataset/extract
capabilities are offered but their request/response contracts are not publicly
documented and are intentionally not fabricated here.
