Listing source in API

Sure it is, but you need to use Process API, not OGC. Find some example here:

Examples for S2L1C

Use these CURL and Postman examples to access Sentinel-2 L1C data with Sentinel Hub Processing API.

(the “type” parameter)

Hi, I receive the following error when calling the above API:

{
“error”: {
“status”: 500,
“reason”: “Internal Server Error”,
“message”: “MessageBodyReader not found for media type=application/octet-stream, type=class io.jsonwebtoken.impl.DefaultClaims, genericType=class io.jsonwebtoken.impl.DefaultClaims.”,
“code”: “RENDERER_EXCEPTION”
}
}

Can you provide the actual API request?

I got the required solution, thanks.
