Phone Specification vs Phone Validation

Phone Specs API is an open-source, keyless wrapper around GSMArena's device database, returning brand lists, per-phone specifications, and search results as JSON — maintained by a single developer (Azhari Muhammad M) and deployed on Vercel. Both README-documented custom domains (api-mobilespecs.azharimm.dev for v1, phone-specs-api-2.azharimm.dev for v2) no longer resolve, but the underlying Vercel deployment is still live and reachable directly: its root endpoint returned a 200 JSON payload confirming auth "None" and https true, and a live OPTIONS preflight carried Access-Control-Allow-Origin: * (cors reconfirmed "yes"); the /brands and /latest routes intermittently 500 with a 429 from the upstream GSMArena scrape target, a source-side rate-limit rather than the API itself being down.

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.
