Example input: octocat or github:octocat.
Supports GitHub-compatible handles, optionally prefixed with github:. Preserves provider namespace, numeric account ID and account type. A handle match is a candidate and does not link accounts across platforms.
Coverage and interpretation
GitHub only. One unauthenticated public API request. No private contacts, followers, account recovery or cross-platform enumeration. Missing or renamed profiles do not prove availability or absence elsewhere.
Public observations are not proof of real-world identity. Review candidate records against their cited sources. Saved investigations preserve evidence acquisition times and provider provenance; these timestamps do not establish when a profile or fact first existed.
