{"jsonrpc":"2.0","id":1,"method":"tools/list"}hospital_price_search — What hospitals near a US ZIP charge for one service, from the standard charges files each hospital publishes under the CMS price transparency rule. Per hospital: gross charge (list price, not what anyone pays), self-pay discounted cash price, the de-identified min/max negotiated amounts, and a summary of payer-specific negotiated dollar rates; pass payer and/or plan to get that payer's negotiated rate rows. Each rate carries dollar_available: when a hospital published a percentage or formula instead of a dollar amount it says so and gives the hospital's own text rather than a number. COVERAGE IS PARTIAL AND STATED (the store is loaded state by state; each response lists the states loaded): every response says how many hospitals in range have prices loaded, why others do not (the hospital's site blocks us, no file found, ...), and distinguishes "no hospital in range", "hospital held but code absent" and "code present but payer not listed". Holds only the CMS 70 shoppable CPT/HCPCS services and MS-DRGs. Use for "what does a head CT cost near 02139", "MS-DRG 470 near 10016 for Aetna".hospital_price_compare — Side-by-side prices for one service at up to 10 named hospitals (by CMS Certification Number, CCN, from hospital_price_search or hospital_price_coverage). Same fields and same labelling as hospital_price_search: gross charge vs self-pay cash vs payer-negotiated rates, dollar_available on every negotiated rate, and for each hospital that has no price a stated reason (not held and why / code absent / payer not listed). Use for "compare MS-DRG 470 at these three hospitals for Blue Cross".hospital_price_coverage — Whether this store holds a hospital's prices and, if not, WHY. Look up one hospital by CCN or by name (partial match), or summarise a state, or (no arguments) the whole store, including which states are loaded (the store is loaded state by state, so a hospital in an unloaded state is simply absent). Every hospital in a loaded state has a status: ok (prices held), blocked (its website refuses our requests; we do not evade blocks), not_found (no machine-readable file found), invalid_pointer, soft_404, unsupported_version, too_large, parse_error, no_matching_codes, not_fetched. Use before trusting an empty hospital_price_search, or to answer "does this tool cover Mayo Clinic".Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
