      summary: Get Credit Status Endpoint
      description: 'Machine-readable CEO operational credit health.


        Designed for agent consumption: an agent can poll this endpoint

        before negotiating an expensive deal to avoid wasted round trips

        when the credit pool is exhausted. The CEO dashboard also reads

        this via a same-origin proxy.


        Public surface intentionally minimal -- exposes health band,

        utilization percentage, and remaining USD headroom but NEVER the

        raw PHP credit limit. The raw limit is operationally sensitive

        (gives an attacker the exact spending ceiling); the available_usd

        figure is the only number an external agent legitimately needs.


        Distinct from the older /credit-health endpoint (zero-state

        scaffold from Phase 36, never wired to ap2_executions). This

        endpoint reads live spend data. /credit-health is preserved for

        backward compatibility with the boardroom Credit Tank widget.


        No authentication required -- safe-by-design response surface.'
