 See the [Rate Limit](https://www.aftership.com/docs/tracking/quickstart/rate-limit) to understand the AfterShip rate limit policy.
 
-The API returns the current rate limit status in the headers of **every** response, and the SDK exposes them on both successful and failed requests, so you can monitor your consumption proactively instead of waiting for `429` errors.

-### On successful requests
+The API returns its current rate limit status in the headers of every response, and the SDK exposes these headers on both successful responses and rate-limited errors, so you can monitor your consumption proactively instead of waiting for `429` errors.
 
-Every successful response contains a `response_headers` object alongside `data` (available since v15.0.0):

-import { AfterShip } from "@aftership/tracking-sdk";
-
-const aftership = new AfterShip({ api_key: "<your_api_key>" });
-
-const result = await aftership.tracking.getTrackings();
+Every successful response exposes a `response_headers` object alongside `data` (header names are lower-cased). Taking the Quick Start example above:
 
-console.log(result.data.trackings);
-
-// Rate limit status for this endpoint
-const limit = Number(result.response_headers["x-ratelimit-limit"]);
+```javascript
 const remaining = Number(result.response_headers["x-ratelimit-remaining"]);
 const resetAt = Number(result.response_headers["x-ratelimit-reset"]);
 
 if (remaining <= 1) {
-  // Throttle or defer lower-priority workflows before hitting the limit
+  // Throttle or defer lower-priority requests until `resetAt`
 }
 ```
 
-### On rate-limited requests
-
-When the limit is exceeded, the SDK throws an `AftershipError` with `code = TOO_MANY_REQUEST`. The same headers are available on the error:
-
-```typescript
-try {
-  await aftership.tracking.getTrackings();
-} catch (e) {
-  if (e.code === "TOO_MANY_REQUEST") {
-    const resetAt = Number(e.response_headers["x-ratelimit-reset"]);
-    // Wait until resetAt before retrying
-  }
-}
-```
+When the rate limit is exceeded, the request fails with a `429` error that carries the same headers — see [Error Handling](#error-handling).
