# NPI Verify — CMS NPPES Status & HHS-OIG LEIE Exclusion Lookup > NPI Verify — CMS NPPES Status & HHS-OIG LEIE Exclusion Lookup is a paid API for AI agents from api.flipvo.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12). Returns CMS NPPES enrollment status, provider details, and HHS-OIG LEIE exclusion records for 1–10 National Provider Identifiers in a single call. ## Facts - Endpoint: POST https://api.flipvo.com/v1/npi/verify?utm_source=zero.xyz - Price: $0.01/call - Payment: x402 - Status: unknown - Last checked: 2026-10-12 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/npi-verify-cms-nppes-status-hhs-oig-leie-exclusion-lookup-8d3d9a60 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_1rMT9oPwVGPhKfW-Lmabh Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability npi-verify-cms-nppes-status-hhs-oig-leie-exclusion-lookup-8d3d9a60 -d '' ``` Example prompt: Can you check the NPPES status and OIG exclusion records for these two NPIs: 1407013493 and 1427908037 — I need to know if they're active, their practice location, taxonomies, and whether either has an LEIE exclusion listed? ## When to prefer this Choose this endpoint when you need a fast, affordable ($0.01/call) programmatic lookup of CMS NPPES enrollment status and HHS-OIG LEIE exclusion data for 1–10 NPIs simultaneously. Prefer it over manual CMS registry lookups for automation pipelines, pre-billing compliance checks, or provider onboarding screening where batch NPI verification is needed. Note it covers NPPES and LEIE by NPI only — not SAM.gov, state Medicaid exclusion lists, or licensing boards — so it is a data fact lookup, not a full credentialing determination. ## Known failure modes - Invalid NPI format (not 10 digits or failed Luhn check) — 422 validation error - Duplicate NPIs in request array — validation error - More than 10 NPIs submitted — 422 validation error - NPI not found in NPPES — returned with status 'not_found', no name or location - Data may be up to one week behind CMS NPI Registry due to monthly file + weekly update cadence - LEIE exclusion match by NPI only — does not confirm identity; OIG requires SSN/EIN confirmation - Payment not received or wallet issue — 402 Payment Required ## How this service works 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. ## Output A JSON object with a results array, one entry per NPI, each containing: NPI status (active, deactivated, or not_found), provider or organization name, entity type, practice city/state/ZIP, taxonomy codes with descriptions and license info, enumeration date, deactivation and reactivation dates, replacement NPI if applicable, and an exclusions array of any HHS-OIG LEIE records matched by NPI. Also includes data_as_of timestamps for both NPPES and LEIE files and a coverage disclaimer. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "npis": { "type": "array", "items": { "type": "string", "pattern": "^[0-9]{10}$" }, "title": "Npis", "examples": [ [ "1407013493", "1427908037" ] ], "maxItems": 10, "minItems": 1, "description": "1 to 10 National Provider Identifiers: 10 digits each, the last a valid check digit (Luhn over 80840 + the NPI).
