Wrong API MIME Type

[ibnesayeed]

Find an "in the wild" examples of an API with a MIME type of application/json that should be something else and suggest what the MIME type should be.

curl -i -X OPTIONS https://www.pinterest.com/ HTTP/1.1 405 Method Not Allowed content-type: application/json allow: GET, POST, HEAD, DELETE x-envoy-upstream-service-time: 1 set-cookie: _routing_id="52e16908-d8cd-4fb8-b5c3-9f2163b505a7"; Max-Age=86400; Path=/; HttpOnly x-pinterest-rid: 3843363079112262 Content-Length: 62 Date: Thu, 12 Dec 2019 04:13:48 GMT Connection: keep-alive X-CDN: fastly Pinterest-Generated-By: coreapp-webapp-prod-0a01c065

I would suggest this be text/html or text/plain

[ibnesayeed]

@Neyo-odu 1) this is not an API and 2) it indeed is returning a JSON response.

Expected MIME type - application/javascript

[ibnesayeed]

@himarshaj you did not quote the URI which contains & in it which is interpreted to run the command in the background. You can either escape unsafe characters or simply quote the URI. By doing so, you will note that it returns correct MIME type (i.e., application/javascript when a JSON-P callback function is specified, application/json otherwise).
