Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Can you look up the US healthcare organization with NPI number 1234567890 and give me their details?

## When to prefer this

Use this endpoint when you need to look up US healthcare organizations from the National Provider Identifier (NPI) registry — either by exact 10-digit NPI number for a direct match, or by organization name prefix and state for a name-based search. Prefer this over general web search when you need structured, authoritative provider data including NPI numbers, organization names, and locations.

## Known failure modes

- Invalid NPI format (must be exactly 10 digits) returns an error
- Providing both NPI and organization_name simultaneously is rejected
- organization_name without state returns an error
- No matching providers found returns an empty result set
- State code not in valid two-letter uppercase format causes a validation error
- City wildcard with fewer than two preceding characters is rejected
