Username Search API

base /username-osint/v11 endpoints

post/username-osint/v1/username3 credits

Find every public account for a username across 3000+ sites (powered by the Maigret OSINT engine) → for each site where the account exists: the platform + the public profile link. Also accepts a Steam numeric ID or profile URL (steamcommunity.com/profiles/...). Scan the top-N most-popular sites (default 300), filter by tag (gaming/social/coding/…), or deep-scan to extract linked identifiers.

Parameter		Allowed / range	Description
username	required	—	The public username/handle to check across the platform stable-set. A public handle, NOT an email or phone. Letters, digits, . _ - only.
top = 300	optional	—	How many of the most-popular sites to scan (20-500). More sites = broader coverage but slower. Default 300 (~15s).
tags	optional	—	Restrict the scan to Maigret site tags (e.g. gaming, social, coding, photo, music, forum, finance, us, ru). Comma-separated. Default = all.
sites	optional	—	Restrict the scan to these exact platform names (case-insensitive). Default = the full stable-set for the input type. Unknown names ignored.
deep = false	optional	—	Parse found profiles to extract linked identifiers (other usernames, ids, names) for pivoting. Slower. Default false.
