What is Account Finder?

Account Finder is an email lookup and account search service. Given an email address, it discovers which online services have a registered account tied to that address. In most cases it confirms that an account exists on a service; in some cases it can also return additional profile details such as name, username, avatar, bio, linked accounts, or creation date. It is used for OSINT investigations, fraud prevention, due diligence, and digital footprint analysis.

How does email-to-account lookup work?

You submit an email address. Account Finder queries 170+ online services in parallel to check whether each service has a registered account associated with that email, then aggregates the matches into a single response grouped by service category with whatever profile enrichment each service exposes.

How fast are results?

Most searches complete in under 15 seconds. A live progress indicator is shown while the lookup runs.

Are my searches stored?

No. Searches are encrypted in transit and are not persisted. Account Finder does not retain query history per user.

Yes. Account Finder is available as a hosted API on RapidAPI, with an interactive playground for trying requests and copying client code. The free tier is rate-limited; HTTP 429 is returned when the limit is hit.

How is Account Finder different from Holehe and Epieos?

Compared to Holehe, Account Finder is a maintained web service with no install, covers 170+ services, and returns richer per-service profile enrichment. Compared to Epieos, it offers an open, documented API with predictable pricing via RapidAPI instead of a closed tool.

Is it legal to look up accounts by an email address?

Account Finder is intended for authorized OSINT, fraud investigation, due diligence, and checking your own digital footprint or accounts you have permission to investigate. It must not be used for harassment, doxxing, stalking, or unauthorized surveillance. Users are responsible for complying with applicable law in their jurisdiction.
