The API explorer doesn't handle it well either https://api.govinfo.gov/docs/

@cnizzardini - the first request is failing because CREC packages (and granules) do not have an XML representation of the content. The API is handling your request for an XML of the content and the server is returning our standard 404 for content that doesn't exist. You may want to add the -L switch to your curl request so that your request follows internal server redirects:

$ curl -L -X GET "https://api.govinfo.gov/packages/CREC-2018-01-04/granules/CREC-2018-01-04-pt1-PgD7-3/xml?api_key=DEMO_KEY" -H "accept: /"

Your options for content download for the granule you're looking for is available via the summary endpoint. e.g.:

curl -X GET "https://api.govinfo.gov/packages/CREC-2018-01-04/granules/CREC-2018-01-04-pt1-PgD7-3/summary?api_key=DEMO_KEY" -H "accept: /"

The download section in the summary shows:

"download": {
		"txtLink": "https://api.govinfo.gov/packages/CREC-2018-01-04/granules/CREC-2018-01-04-pt1-PgD7-3/htm",
		"pdfLink": "https://api.govinfo.gov/packages/CREC-2018-01-04/granules/CREC-2018-01-04-pt1-PgD7-3/pdf",

		"zipLink": "https://api.govinfo.gov/packages/CREC-2018-01-04/zip"
	}

MODS and PREMIS present descriptive and preservation metadata about the content in xml format.

You'll see that performing a request for the htm rendition does return content as expected in curl:

$ curl -X GET "https://api.govinfo.gov/packages/CREC-2018-01-04/granules/CREC-2018-01-04-pt1-PgD7-3/htm?api_key=DEMO_KEY" -H "accept: /"

The API documentation page isn't really intended for curling in that manner -- since that /docs is a page that then fires off several requests to serve the swagger.json file in a (human) user-friendly manner

You could also just request the swagger.json directly via https://api.govinfo.gov/swagger.json

I hope that helps.
