+`await`ed. Install the async extra:
+
+```shell
+pip install "datamaxi[async]"
+```

+# Async client
+
+The SDK ships an async client, `AsyncDatamaxi`, built on
+[httpx](https://www.python-httpx.org/). It mirrors the sync
+[`Datamaxi`](api.md) resource tree — the same endpoints and arguments — with one
+rule: every method is a coroutine and must be `await`ed.
+
+Every endpoint page in this documentation carries a **Sync** / **Async** tab —
+switch to the *Async* tab to see the awaited twin of that page's example.
+
+## Installation
+
+The async client requires the `async` extra, which pulls in `httpx`:
+
+```shell
+pip install "datamaxi[async]"
+```
+
+## Lifecycle
+
+Use `AsyncDatamaxi` as an async context manager so the underlying `httpx` client
+is closed cleanly, or call `await client.aclose()` yourself. It reads the same
+`DATAMAXI_API_KEY` environment variable as the sync client.
+
+```python
+import asyncio
+from datamaxi.aio import AsyncDatamaxi
+
+
+async def main():
+    # Reads DATAMAXI_API_KEY from the environment, or pass api_key=... explicitly.
+    async with AsyncDatamaxi() as client:
+        df = await client.cex.candle(
+            exchange="binance", symbol="BTC-USDT", interval="1d", market="spot"
+        )
+        print(df.head())
+
+
+asyncio.run(main())
+```
+
+Without a context manager, close the client explicitly:
+
+```python
+client = AsyncDatamaxi()
+try:
+    df = await client.cex.candle(
+        exchange="binance", symbol="BTC-USDT", interval="1d", market="spot"
+    )
+finally:
+    await client.aclose()
+```
+
+## Notes
+
+- Every data and discovery method is a coroutine — `await` it (e.g.
+  `await client.cex.candle.exchanges(market="spot")`).
+- Telegram and Naver have standalone async clients, `AsyncTelegram` and
+  `AsyncNaver`, also imported from `datamaxi.aio` and used the same way (async
+  context managers, awaited methods). See the [Telegram](telegram.md) and
+  [Naver Trend](naver-trend.md) pages for tabbed examples.
+
+## Pagination
+
+Paginated endpoints return an **async** `next_request` callable — `await` it too:
+
+```python
+data, next_request = await client.cex.announcement(page=1, limit=100)
+data2, _ = await next_request()
+```
