Magento REST API – Specified request cannot be processed and Class does not exist

Class \Vendor\ModuleName\Api\TestInterface does not exist

During development move things from local-src + symlink to app/code/{vendor}/{modulename} so that namespace and folder structure could match.

If you are using interfaces in your module then this is also true that you need to use full path reference in PHPdoc instead of use import and reference.

Both worked for me

Specified request cannot be processed

rest/V1/test/ – V in version needs to be capital letter (also in webapi.xml).

And just useful tip that you can extract interface out of existing class.
