 - [application/vnd.ipld.car](https://www.iana.org/assignments/media-types/application/vnd.ipld.car) – disables [IPLD codec deserialization](https://ipld.io/docs/codecs/), requests a verifiable [CAR](https://docs.ipfs.io/concepts/glossary/#car) stream to be returned
 - [application/x-tar](https://en.wikipedia.org/wiki/Tar_(computing)) – returns UnixFS tree (files and directories) as a [TAR](https://en.wikipedia.org/wiki/Tar_(computing)) stream. Returned tree starts at a root item which name is the same as the requested CID. Produces 400 Bad Request for content that is not UnixFS.

If the requested CID already has `dag-json` (0x0129) codec, data is validated as DAG-JSON before being returned as-is. Invalid DAG-JSON produces HTTP Error 500.

 - [application/cbor](https://www.iana.org/assignments/media-types/application/cbor) – same as `application/vnd.ipld.dag-cbor`, unless the CID's codec already is `cbor` (0x51). Then, the raw CBOR block can be returned as-is without any conversion.
 - [application/vnd.ipfs.ipns-record](https://www.iana.org/assignments/media-types/application/vnd.ipfs.ipns-record) – requests a verifiable :cite[ipns-record] to be returned. Produces 400 Bad Request if the content is not under the IPNS namespace, or contains a path.
