Deep health check (exercises DIDKit end to end)

get

Issues and verifies a test credential + presentation with the service keypair, proving the full DIDKit crypto path (plugin load, signing, and the runtime delegation inside the native plugin) works. Reports which DIDKit engine loaded. Added after the 2026-07-02 incidents, where shallow health checks stayed green while DIDKit paths were broken.

Resolve a recipient locale by email

post

Returns the account's saved BCP-47 locale preference for this email, or null when no preference is set or no account exists. Returning null (rather than defaulting to 'en') lets the caller fall back to its own signal (e.g. the client UI locale) before English. Never reveals whether an account exists — a missing account and an account with no saved locale both return null — so it is safe to call before authentication (e.g. to localize a login-code email). Rate limited to 10 lookups per email per hour (plus a broad per-IP circuit breaker); callers should treat any error as an unresolved locale and fall back, never as a failure.
