SignupBear reports both overall status and per-signal coverage. Check these
fields when you send more than an email.
Status
Coverage
Each signal in coverage is one of:
complete: evaluated by the current policy
unavailable: requested, but the capability is not currently available
not_requested: not included in the request
During private beta, an email-only request normally returns:
An email and IP request normally returns status: "partial" because IP checks
are not yet available.
An IP-only request is accepted by the API, but returns HTTP 200 with
status: "failed", risk_level: "unknown", and recommended_action: "flag".
Do not treat HTTP 200 alone as permission to create an account.
