+#### `ses.fetch(input[, init])`
+
+* `input` string | [GlobalRequest](https://nodejs.org/api/globals.html#request)
+* `init` [RequestInit](https://developer.mozilla.org/en-US/docs/Web/API/fetch#options) (optional)
+
+Returns `Promise<GlobalResponse>` - see [Response](https://developer.mozilla.org/en-US/docs/Web/API/Response).
+
+Sends a request, similarly to how `fetch()` works in the renderer, using
+Chrome's network stack. This differs from Node's `fetch()`, which uses
+Node.js's HTTP stack.
+
+Example:
+
+```js
+async function example () {
+  const response = await net.fetch('https://my.app')
+  if (response.ok) {
+    const body = await response.json()
+    // ... use the result.
+  }
+}
+```
+
+See also [`net.fetch()`](net.md#netfetchinput-init), a convenience method which
+issues requests from the [default session](#sessiondefaultsession).
+
+See the MDN documentation for
+[`fetch()`](https://developer.mozilla.org/en-US/docs/Web/API/fetch) for more
+details.
+
+Limitations:
+
+* `net.fetch()` does not support the `data:` or `blob:` schemes.
+* The value of the `integrity` option is ignored.
+* The `.type` and `.url` values of the returned `Response` object are
+  incorrect.
