HTTP 200 returns the success variant. Check status: partial means usable data with warnings, and failed or challenged requests carry a failure object described in Errors & responses.

Error codes

HTTP	failure.code	Meaning
400	`invalid_request`	The request failed validation.
401	`invalid_request`	The internal service secret is invalid.
503	`upstream_error` `breaker_open`	Proxy unavailable or thread retrieval temporarily paused.
502	`upstream_error`	Retrieval failed.
504	`timeout`	The deadline expired; available results are retained.
200	`partial` `challenged`	Inspect status and failure even when HTTP succeeds.
