Cloudmersive Validate vs Veriphone

Cloudmersive's Phone Number Validation API parses and standardizes global phone numbers, returning line type, E.164/international/national formats, and country data, with client libraries for over 10 languages. A live OPTIONS preflight against its real API host, api.cloudmersive.com/validate/phonenumber/basic, returned Access-Control-Allow-Origin: * (cors reconfirmed "yes"), and a follow-up unauthenticated POST returned a 401 "Invalid API key or exceeded limits" over HTTPS, reconfirming auth "API Key" and https true. Its pricing page offers 600 free calls/month with no expiration alongside a $2,000/month paid tier — 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.
