Frequently asked questions
Why pay for public NPPES data?
The raw registry means bulk-file wrangling and a rate-limited, awkward upstream API. We sell reliability: clean JSON, fast edge responses, search, batch verification, uptime, and support.
How fresh is the data?
Monthly full NPPES refresh plus weekly incrementals, with automatic live-registry fallback for records changed in between — the response tells you the source of every record.
How do I get an API key?
Email hello@npiportal.com with your use case while self-serve signup is being finished — Free-tier keys are issued same-day.
Is there an SLA?
Business-tier plans include a 99.9% availability SLA and priority support. The API runs on Cloudflare's edge network in 300+ cities.
