 ### Quick Start
 
 ```python
-from gcf import encode, Payload, Symbol, Edge
+from gcf import encode_generic
 
-p = Payload(
-    tool="context_for_task",
-    token_budget=5000,
-    tokens_used=1847,
-    symbols=[
-        Symbol(qualified_name="pkg.AuthMiddleware", kind="function", score=0.78, provenance="lsp_resolved", distance=0),
-        Symbol(qualified_name="pkg.NewServer", kind="function", score=0.54, provenance="lsp_resolved", distance=1),
-    ],
-    edges=[
-        Edge(source="pkg.NewServer", target="pkg.AuthMiddleware", edge_type="calls"),
+output = encode_generic({
+    "employees": [
+        {"id": 1, "name": "Alice", "department": "Engineering", "salary": 95000},
+        {"id": 2, "name": "Bob", "department": "Sales", "salary": 72000},
     ],
