Re: spec key aliasing or different specs for same keyword
You could always extract specific keys from the payload and validate that,
something like:
(GET "/..." req
(let [b (:body req)
data {:my/result (:resultCount b)
:my/other-key (get-in b [:some :path])}]
(my-business-logic data)))
i.e. spec what your code (my-business-logic here) expects, not the API call
itself.

Re: spec key aliasing or different specs for same keyword
Yes, the namespacing is great, so I have no issue with that. I would just rather use snake-case in Clojure than camel-case. Since the payload has 'resultCount' I'd like to map that to a spec named result-count instead. I think I figured out part of the answer: (s/def :my/result int?) (s/def :your/result pos-int?) (s/def ::test-spec-1 (s/keys :req-un [:my/result])) (s/def ::test-spec-2 (s/keys :req-un [:your/result])) I see here that I can have an unqualified keyword as part of a qualified spec name. I think that's what I want.

Re: spec key aliasing or different specs for same keyword
Avoiding global name collision is the reason why specs are named with namespace-qualified keywords. I am confused by your last sentence though. Do you mean Clojure namespaces or the namespace component of the keyword itself? There is no requirement in clojure.spec that the namespace of the specs you def be coupled to the Clojure namespace they happen to be defined in. If you are actually asking about how to write specs for unqualified keys in a map there is a built-in facility to do that as well: clojure.spec.alpha/keys has a :req-un and :opt-un argument.

spec key aliasing or different specs for same keyword
I have one spec question covering two scenarios. 1. Suppose I want to spec a payload from a third-party API that has the keyword ':resultCount' in it. Does that mean my specs for that item must have the same name? 2. Supposed I have a few payloads from that API and each has a keyword ':result' but the spec for each will be different. Other than using an entirely different namespace, how can I map the :result keyword to different specs?
