Completely untested, but something like:

  map $arg_key $key_ends_in_02X {
    default "";
    ~02X$ "A";
  }

(where "A" might be, for example, $binary_remote_addr, if you want to
limit the requests per client IP, rather than enforce the limit across
all clients where "key" ends "02X")

and then

  limit_req_zone $key_ends_in_02X zone=two:10m rate=2r/s;

and

  limit_req zone=two;

should probably do what you asked for.

If anything is unclear or broken, and the documentation doesn't make
it clear how it should be, then feel free to respond pointing out which
specific parts need fixing.

Cheers,
