About this endpoint
Checks a US phone number against the US Do Not Call list. A successful check costs one credit whether the number is listed or not. Non-US and malformed numbers are rejected before the lookup. The original /v1/dnc-check route accepts the same request and returns the same response for existing integrations. For UK numbers, use /v1/uk-dnc-check.
