Numlookup vs Veriphone

Numlookupapi.com (an Everapi GmbH product) validates phone numbers and returns formatting, country, location, carrier, and line type via a REST endpoint that takes the number as a path parameter. A live OPTIONS preflight against its real API host, api.numlookupapi.com/v1/validate/, returned access-control-allow-origin echoing the request Origin plus access-control-allow-credentials: true, resolving the stored "unknown" cors to "yes"; a follow-up unauthenticated GET returned a 401 with www-authenticate: Key and a missing_api_key JSON error, confirming auth "API Key" over HTTPS. Its pricing page offers a Free plan (100 requests/month) alongside paid Basic/Pro/Scale 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.
