Get a free key — 30 seconds.

Email in, key out. No password, no dashboard, no sales call — just paste it as a Bearer token and make your first call.

We email you the key and use your address to send quota notices. No password, no dashboard, no spam.

What the free key gets you

  • 500 calls / month
  • Identity fields — name, location, NPI, taxonomy
  • US-wide identity layer (all specialties) + every live vertical
  • Compliance signals & price visible, locked until you upgrade

The free plan is for evaluation and non-commercial use. Production or commercial use needs a paid plan — Builder is $99/mo, card checkout, full fields. If you display free-tier data publicly, please credit Data: xcircl.com.

We email a heads-up at 80% of your quota, and again when you hit it.
