Ways to get the data

  • API

    Targeted queries

    Search and filter, pull supporting records, and compute averages, medians, percentiles and benchmarks.

  • MCP

    For AI agents

    The same data as tools your assistant can call: procedures, hospitals, rates and the source files.

  • Files

    Bulk delivery

    Flat files for warehousing and model work, or a bulk load with API refreshes on top.

What you can query

One normalized shape across every hospital.

Start narrow, with one code, one hospital or one state, and widen as you go.

  • CPT, HCPCS, DRG, APC, NDC and other code types
  • Hospital and health system
  • Geography
  • Payer and plan
  • Negotiated rate, cash price and price type
  • Inpatient or outpatient setting
  • Effective and file dates

Pricing

Pay for the records you use.The more you use, the less each costs.

Each rate applies only to the records inside its tier, and totals reset every year. Going past a tier never reprices what you've already used.
