+# agentic-os-api
+
+The coordination service for the **agentic operating system** — agent pods
+pursuing objectives across the estate under a governed capture cadence.
+
+Serves the canonical agentic-OS objects (`Opportunity` / `AgentPod` /
+`ReadinessScore` / `CaptureCadence`) that the cockpit console renders and the
+pods coordinate against. Object shapes conform to the **sourceos-spec**
+agentic-OS contract and compose over **prophet-workspace** (ProfessionalWorkroom
+/ OrgGovControlRoom) and **prophet-mesh** (agent-choir + estate graph).
+
+Read-only seed today; a live registry adapter will resolve the same URNs from the
+workspace + estate graph.
+
+## Endpoints
+- `GET /health`
+- `GET /opportunities` · `GET /opportunities/{slug}` (with readiness + cadence)
+- `GET /pods`
+- `GET /cadence`

+## Run
