# Call Clearance

> Pre-call compliance for AI voice and SMS agents calling US numbers. Before a number is dialed or texted, Call Clearance runs up to six checks (opt-outs, consent on file and calling hours on every account; the National Do Not Call Registry, state lists and known litigators where that data is set up; see https://callclearance.com/coverage), answers allow or block typically in well under a second, and keeps a sealed Call Record that is chained, published daily and timestamped on the Bitcoin blockchain so any later change is detectable. A check that cannot run says "skipped", never "passed". Free plan, no card. Made by Call Clearance LLC (US). Compliance tooling and records, not legal advice.

The check sits in front of the dial request (POST api.callclearance.com/v1/check, or POST /v1/call to place the call through the customer's own Retell or Vapi account on allow). A tool inside a voice agent runs after the phone has rung, which is too late. Consent is required by default on both channels; a caller can set require_consent to false and the record says the check was skipped at their request.
