+# NAME
+
+CURLOPT_DOH_SSL_VERIFYSTATUS - verify the DoH SSL certificate's status
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DOH_SSL_VERIFYSTATUS,
+                          long verify);
+~~~
+
+# DESCRIPTION
+
+Pass a long as parameter set to 1 to enable or 0 to disable.
+
+This option determines whether libcurl verifies the status of the DoH
+(DNS-over-HTTPS) server cert using the "Certificate Status Request" TLS
+extension (aka. OCSP stapling).
+
+This option is the DoH equivalent of CURLOPT_SSL_VERIFYSTATUS(3) and
+only affects requests to the DoH server.
+
+If this option is enabled and the server does not support the TLS extension,
+the verification fails.
+
+# DEFAULT
+
+0
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
+
+    curl_easy_setopt(curl, CURLOPT_DOH_URL,
+                     "https://cloudflare-dns.com/dns-query");
+
+    /* Ask for OCSP stapling when verifying the DoH server */
+    curl_easy_setopt(curl, CURLOPT_DOH_SSL_VERIFYSTATUS, 1L);
+
+    curl_easy_perform(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
