Use for provider credentialing, healthcare due diligence, billing verification, or AML/KYB screening on medical payments.

Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/npi-lookupWhen to prefer
Use this endpoint when you need to verify or retrieve NPI provider details without setting up accounts or API keys, paying only $0.004 USDC per lookup via x402 on Base mainnet. Ideal for healthcare data enrichment, provider credentialing checks, or validating NPI numbers programmatically in agent workflows.
Side effects
- NPI number not found — no matching record in registry
- Invalid NPI format — NPI must be a 10-digit number
- Provider not found by name search — try more specific parameters
- Rate limit or payment failure on x402 — retry with sufficient USDC balance
- Ambiguous query returns multiple results — narrow search criteria
