Phone Validation vs VeriRoute Intel

AbstractAPI's Phone Validation API checks whether a number is real, and returns its carrier, line type, risk score, and registered location, from a single GET request. The stored url redirected (301) to /api/phone-validation-api, now recorded as the canonical link. A live GET against its real host, phonevalidation.abstractapi.com/v1/, returned Access-Control-Allow-Origin: * (cors reconfirmed "yes") and a 400 validation error demanding the api_key parameter, confirming auth "API Key" over HTTPS. Its landing page advertises 100 free requests with no credit card required, ahead of paid usage tiers — freemium.

VeriRoute Intel is a live phone-intelligence platform offering CNAM caller-ID lookup, LRN/carrier routing lookup, message-provider identification, and spam/fraud scoring for North American numbers, served from verirouteintel.com/api/v1/<service>. A live OPTIONS preflight against its real API host carried no Access-Control-Allow-Origin header at all, resolving the stored "unknown" cors to "no"; a follow-up unauthenticated GET returned a 401 "API key required" JSON error over HTTPS, confirming auth "API Key" and https true. Its pricing page is strictly pay-as-you-go per query (from $0.0005/lookup) with a free sandbox and no subscription requirement — metered.
