Retrieve a Liveness Check Result API
/liveness_check
Retrieves the status or final result of a liveness check using the token returned from the create endpoint. Idempotent and safe to poll. Returns 202 while the check is pending or in progress, 200 when complete (with result object), and 410 if the link expired without completion.

Technical Use Cases tag
Backend polling integration
Poll from a server-side worker with exponential backoff (start at 2 to 3 seconds and back off) until the check reaches a terminal status. Stop polling once HTTP 200 is received.
Audit image retrieval
Pull intermediate audit frames (within around 30 minutes of completion) for case review or compliance archival.

How long do audit images stay available?

How long do audit images stay available?
Around 30 minutes after the check completes. After that, the same result is still returned, but without images.

What's the lifecycle?
A check progresses through pending (created but not started), then in_progress (capture active), then complete / expired / failed (terminal). HTTP 202 is returned while pending or in_progress. HTTP 200 once complete. HTTP 410 if expired without completion.

Should I trust the client-side redirect lc_token?
Never. Always validate the result via this authenticated GET call from your backend. The redirect parameter could be tampered with before reaching you.
