Telegram Number Validation & Profile Lookup APIs
Telegram lookup API: verify if a phone number is registered on Telegram and fetch public profile (username, display name, About, premium/verified/scam flags, last seen). Real-time JSON API for lead validation, quality scoring, and contact enrichment.
Telegram Lookup by Phone Number
Check whether a phone number is registered on Telegram and, when registered, return its public profile in one call: username, display name, About bio, Telegram user ID, common-chats count, phone/video call availability, last-seen timestamp (Unix seconds), and flags (premium, verified, bot, scam, fake, deleted, restricted, inactive). Pass the full international number (digits, with country code); the API normalizes to digits only. When the number has no Telegram account, registered=false is returned.
