 ### APIs
 
 New APIs:
-- `POST /api/v1/nlp-to-query` - Convert natural language to structured query
-- `POST /api/v1/structured-data/ingest` - Ingest structured data (CSV, JSON, XML)
-- `POST /api/v1/structured-data/query` - Execute structured queries
-- `GET /api/v1/schemas` - List available schemas
-- `GET /api/v1/schemas/{name}` - Get specific schema definition
+  - Pulsar schemas for above types
+  - Pulsar interfaces in new flows
+  - Need a means to specify schema types in flows so that flows know which
+    schema types to load
+  - APIs added to gateway and rev-gateway
 
 Modified APIs:
 - Knowledge extraction endpoints - Add structured object output option
