1Request

First address line as filed with NPPES, which uses USPS abbreviations - 200 First St SW, not 200 First Street Southwest. It cannot be searched alone, which is why city is required alongside it.

City of the same address. Required because NPPES rejects an address-line-only search with 'No valid search criteria provided'.

Two-letter state code; worth adding because the same street and city name recur across states.

ZIP code; a 5-digit value prefix-matches the stored ZIP+4.

Ask with this source

A prompt for your agent that names this source and how to call it through the crw MCP.

  • Providers at a street address

    Use NPI Registry (npi) from fastCRW Pergamon, capability "Providers at a street address" (address). You have a building or practice address and want to know who bills from it. Example options: address_1=200 First St SW, city=Rochester, state=MN. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "npi" and capability "address". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Providers in a ZIP code

    Use NPI Registry (npi) from fastCRW Pergamon, capability "Providers in a ZIP code" (area). You want to see who practises in a geographic area and have neither a name nor a specialty to anchor the search. Example options: postal_code=55905, enumeration_type=NPI-1, city=Rochester. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "npi" and capability "area". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Organizations by authorized official

    Use NPI Registry (npi) from fastCRW Pergamon, capability "Organizations by authorized official" (authorized-official). You have the name of an executive or owner and want every healthcare entity registered under them. Example options: last_name=Gonzalez, first_name=Maria, city=Houston. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "npi" and capability "authorized-official". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Medicare enrollment records

    Use NPI Registry (npi) from fastCRW Pergamon, capability "Medicare enrollment records" (medicare-enrollment). You need to confirm an NPI is actually enrolled in Medicare, in which states and under which provider types, rather than merely enumerated in NPPES. Example options: npi=1003000126, size=100, offset=0. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "npi" and capability "medicare-enrollment". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
