Phone Validation vs Veriphone

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.

Veriphone validates phone numbers and returns carrier, line type (mobile/fixed/VoIP), and formatted output for 243 countries, either via a single lookup or bulk CSV upload. Its own docs state "CORS is enabled on all endpoints," and a live OPTIONS preflight plus an unauthenticated GET against api.veriphone.io/v3/verify both returned Access-Control-Allow-Origin echoing the request Origin, reconfirming cors "yes"; the GET also returned a 400 JSON error demanding the key parameter, reconfirming auth "API Key" over HTTPS. Its pricing page offers 1,000 free validations/month with no credit card required, alongside one-time credit packs and monthly subscription tiers — freemium.
