Fetch\Http\Response

Response extends Guzzle's PSR-7 response and implements Fetch\Interfaces\Response and ArrayAccess. The interface is the stable type to use for type declarations.

Body readers: json(), object(), array(), text(), body(), blob(), arrayBuffer(), and xml(). Status readers include status(), statusText(), statusEnum(), isStatus(), exact named helpers such as isNotFound(), and groups such as successful(), isRedirection(), isClientError(), isServerError(), and failed(). Note ok() means any 2xx code, while isOk() means exactly 200.

Content helpers: contentType(), contentTypeEnum(), hasJsonContent(), hasHtmlContent(), and hasTextContent(). Header methods include PSR-7 methods plus headers() and header(string $name): ?string. get(string $key, mixed $default = null) reads a decoded JSON field. Debug metadata is available with getDebugInfo() when attached.

There is no isSuccess() or isJson() response method. Use successful() and hasJsonContent() respectively.
