What We Verify

Every medical specialty, every state, one engine

Most verification services cover MDs and DOs only. We cover the full range of medical specialties — including the underserved ones (ND, DC, L.Ac., DPT, LMT) that millions of patients see every year.

How It Works

Three steps to verified

Every verification produces a SHA-256 evidence hash, timestamp, and full provenance — so you can prove you verified.

No Account Required

Call the API. That's it.

Verify is built headless-first. No login, no signup, no account, no credit card for the free tier. Just an HTTP call. The free tier is 100 lookups/day, no key required, rate-limited by IP.

→ Use Cases
Embed in your directory: Show a "Verified by Signal Loom AI" badge next to any provider with a known NPI.
Verify at onboarding: Telehealth platforms can verify a provider's license the moment they sign up — no account needed.
Use in your CLI: curl + jq gives you a verification record in 100ms.
Power an AI agent: Any LLM with HTTP access can call the API to verify providers autonomously.
Why Verify
