HackerRank Stats API

Fundamentals profile analytics for tracks, badges, contests, submissions, and practice progress.

Every canonical endpoint shares one response envelope across all platforms, so you can swap providers without rewriting your client. Legacy aliases stay available and are clearly marked.

REST JSON No auth {username}

Make your first request

Send a GET request to any handle. Replace demo with the username you want to inspect — no API key required.

Terminal

# Fetch a HackerRank profile
curl /demo/profile

Tip

Prefer a browser? Try the live playground, open /demo/profile for raw JSON, or explore every route interactively in the OpenAPI explorer.

Response envelope

Successful responses follow one consistent shape. The data object carries the endpoint-specific payload while the outer fields stay identical everywhere.

Legacy compatibility

Kept working for existing integrations. Prefer the canonical routes above for anything new.

No legacy aliases — every path already uses the canonical route files.
