What it does

For 1 to 10 NPIs, the CMS NPPES status of each (active or deactivated, with deactivation and reactivation dates), provider name or organization, practice city, state and ZIP and taxonomies, plus any HHS-OIG LEIE exclusion listed under the NPI, as facts from the files: not a credential check and not a determination about the provider.

An NPI is not a license or credential. These are facts from the files, not a determination about a provider: a not_found NPI or an empty exclusions list certifies nothing. The OIG requires a possible match to be confirmed on its online search (https://exclusions.oig.hhs.gov) with the SSN or EIN before any action. Not for employment or credit decisions about a person (FCRA). Not endorsed by CMS or HHS.",

Use with an agent

  1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
  2. Inspect. Fetch /resources/36151.json for the price and payment options.
  3. Pay. Call GET https://api.flipvo.com/v1/npi/verify. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
  4. Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
