Cross-Platform Username OSINT

🔎 Map Usernames Across Public Platforms

Investigators, researchers, trust and safety teams, and developers can check one or more public usernames across selected platform groups. The Actor returns matched rows and, when requested, no-match rows for the username and platform checks that produce a saved status. Rows can include public profile context when a source exposes it. This gives you a structured starting point for a public username footprint review without source credentials. A shared username is a lead, not proof that accounts belong to the same person.

• Check one username across selected public platforms with Cross-platform username search.
• Build a first public account map with Digital footprint search.
• Check a handle across social sites with Social media username checker.
• Look for public accounts tied to a username with Online username search.
• Review where a public username appears with Username lookup.

📊 See Account Matches and Public Context

Each row names the submitted username and the platform checked. A matched row can include a public profile URL, source account ID, profile details, posts, videos, and accounts linked by the source. A presence value of "noMatch" is an explicit no-match row when you turn on Include no-match results. Uncertain or blocked checks are not saved as rows and are not treated as no-match results.

The Actor saves the first eligible occurrence of a source account for a submitted username and platform. If the same source account is found again during discovery, the later match is ignored. The saved row describes only the first match and does not collect evidence from later matches.

▶️ Check Usernames in One Run

1. Add one or more public usernames.
2. Choose the platform categories to check. Leave the list empty to check all non-sensitive groups.
3. Add public federated server domains only when Federated is selected. The list narrows the servers checked and has no effect otherwise.
4. Turn on Include no-match results when you need explicit no-match rows for checks that return no public account.
5. Start the run and open the public dataset.

Each submitted username is checked as its own footprint. A single run processes the submitted list independently.

⚙️ Input

Input fields

Field	Type	What it does
usernames	array of strings	Required. Add one or more public usernames. Each username is checked as its own footprint.
platformCategories	array of strings	Choose social, developer, gaming, forums, media, business, federated, or sensitive. Leave it empty to check all non-sensitive groups.
federatedServers	array of strings	Add public federated server domains, such as mastodon.social. This list narrows checks only when federated is selected and is ignored otherwise.
includeNoMatchResults	boolean	Default false. Turn it on to save an explicit no-match row for each username and platform check that returns no public account. Uncertain or blocked checks stay separate.

Example input

This is the public input from a successful current-beta default-input run:

{
  "usernames": [
    "apify"
  ],
  "platformCategories": [
    "social",
    "developer"
  ],
  "includeNoMatchResults": false
}

🧾 Output

The Output tab opens the public default dataset. Every dataset row has username, platform, and presence. Optional fields appear when the source exposes them. The tables below cover the no-match, profile, post, linked-account, and video row forms seen in successful current-beta runs.

Example matched row with posts and a linked account

💳 Pricing

The Actor uses pay-per-event pricing. The current primary event is $0.036 for each submitted username check. The event is tied to the check, not to the number of rows it saves. No-match rows are written only when requested, and uncertain or blocked checks are not turned into no-match rows.

🔌 Integrations

Read the dataset in the Apify Console or through the standard Apify API. Export the structured rows for your own workflow. The Actor uses public source data and does not need source credentials.

❓ FAQ

How should I read noMatch?

It means the selected source check found no public account for that username, and the check was saved as an explicit no-match row. It does not prove that the username is unused everywhere.

When should I include no-match results?

Turn it on when your review needs explicit no-match rows for username and platform checks that return no public account. Leave it off when you only want matched accounts and their public details.

What happens when a source is uncertain or blocked?

The check is kept separate from noMatch. The Actor does not treat an uncertain or blocked source as proof that an account is absent, and those checks are not saved as dataset rows.

Can I check several usernames in one run?

Yes. Add each public username to the list. The Actor checks each submitted username as its own footprint in the same run.

What does an empty platform category list do?

It checks all non-sensitive platform groups. Sensitive public platforms are checked only when you select Sensitive public platforms.

How do federated servers affect a run?

Select Federated to check public federated accounts. Add server domains to narrow that check. The server list has no effect when Federated is not selected.

Does a shared username prove two accounts belong to one person?

No. A shared username shows public account presence on each source. It is not proof of common ownership or an identity verdict.

Will every matched row include posts or videos?

No. Posts, videos, profile fields, engagement counts, and linked accounts appear only when the source exposes them for that match. The tables above show the fields that can be present.

Does this run continuously monitor accounts?

Each run checks the usernames you submit. Run it again when you need a new check, but the Actor does not combine separate runs or claim change history.

Can it access private or login-gated accounts?

No. It uses public source access and does not bypass privacy controls, login gates, or other access limits.
