It seems there is no configuration for "Rest Api" about magento-nginx-config

[magenx]

what exactly you want to see there?

There is no "Rest Api" configuration for magento. 404 will be returned, if "http://magento.dev/api/rest/products"

[yssource]

If add the following codes in file https://github.com/magenx/Magento-nginx-config/blob/master/magento/www/magento.conf

    location /api {
        #proxy_pass http://varnish;
        rewrite ^/api/rest /api.php?type=rest last;
        rewrite ^/api/v2_soap /api.php?type=v2_soap last;
        rewrite ^/api/soap /api.php?type=soap last;
    }

It will get the result what I need.
The magento_api xml file, which looks like this

<magento_api>
...
<data_item>
<entity_id>16</entity_id>
<type_id>simple</type_id>
<sku>dress7-White-S</sku>
<color>16</color>

for me soap works either way, no need any rewrites, and rest works too if i create user/role and connect with client.

It is very strange.
for me REST does not work me. when "http://mydomain/api/rest/products"
SOAP works for me, when "http://mydomain/api/v2_soap/?wsdl=1".

And In order to make both of soap and rest working for me, I have to add the following rules.

    location /api {
        rewrite ^/api/rest /api.php?type=rest last;
        rewrite ^/api/v2_soap /api.php?type=v2_soap last;
        rewrite ^/api/soap /api.php?type=soap last;
    }
