listing_mismatch

This key belongs to another API

Why it happens

A RapidAPI key of one listing called an endpoint that listing does not serve. Each listing opens its own endpoints, plus the paths every API shares.

What to do

Subscribe to the listing that serves the endpoint (its page names it), or call with a member key, which is not tied to a listing.
