Why we wrap NPPES instead of asking you to parse it

The CMS NPI Registry is the source of truth for NPI data in the United States. It is also a large JSON payload with edge cases across NPI-1 and NPI-2 records, address purposes, and taxonomy rules.

Health Provider API exists so your team does not re-implement the same normalization, caching, and error handling in every service. You integrate against a documented contract and get predictable responses.

That does not replace your compliance obligations—it gives you a cleaner boundary so product and engineering can move faster with fewer surprises when upstream fields shift.
