## When to prefer this

Use this endpoint when you need to verify the legitimacy and details of a US healthcare provider or organization against the official CMS NPI Registry. Ideal for credentialing workflows, insurance claim validation, prior-to-referral checks, and compliance due diligence where NPI status, specialty, and practice location are required. Prefer this over general web searches for authoritative, structured government-sourced provider data.

## Known failure modes

- NPI number not found if the 10-digit number is incorrect or unregistered
- No results returned if name search is too broad or ambiguous without state filter
- Provider may have deactivated NPI that returns inactive status
- Organization vs individual NPI type mismatch if wrong search parameters are used
- Rate limiting or payment failure for x402 protocol at $0.01 per call

## Output
