+API Reference
+=============
+
+The ``pysus.api`` package provides a layered architecture for discovering,
+downloading, and reading data from Brazilian public health databases
+(DATASUS). It supports three remote data sources.
+
+Architecture Overview
+---------------------
+
+The package is organized into a hierarchy of abstract base classes and
+concrete implementations::
+
+    pysus/api/
+    ├── __init__.py          # Package entry (re-exports PySUS)
+    ├── client.py            # Main PySUS orchestrator
+    ├── extensions.py        # File format handlers
+    ├── models.py            # Abstract base classes
+    ├── types.py             # Type aliases
+    ├── _impl/
+    │   └── databases.py     # High-level convenience functions
+    ├── ducklake/            # S3 DuckLake catalog client
+    ├── ftp/                 # FTP client
+    └── dadosgov/            # dados.gov.br API client
+
+Quick Start
+-----------
+
+The simplest way to use PySUS is via the high-level convenience
+functions::
+
+    from pysus import sinan
+
+    df = sinan(disease="dengue", year=2023)
+
+Or with the async API::
+
+    from pysus.api.client import PySUS
+
+    async with PySUS() as pysus:
+        files = await pysus.query(dataset="sinan", group="DENG", year=2023)
+        for f in files:
+            await pysus.download(f)
