Hi!

Thank for writing it. I suggested some changes:

• Added that <contentType> must follow structure of a MIME type, or an error is thrown
• Added that <fileType> must be recognized and translatable to a MIME type, or an error is thrown.
• Use of the word "query parameter" instead of "query", more precise

Thanks!

Suggested change

	- `mime.content=<contentType>`, where `<contentType>`, after URL decoding, sets `Content-Type` field in the response header; or
	- `mime.content=<contentType>`, where `<contentType>` is a URL-encoded [MIME type](https://datatracker.ietf.org/doc/html/rfc6838). If the URL-decoded `<contentType>` does not follow the structure of a MIME type, an error is thrown. After URL decoding, `<contentType>` is set as the value of the `Content-Type` header of the response; or

EIP cannot use the external link. Going to remove the link here.

We do actually allow links to RFCs! See EIP-1 for details.

Suggested change

	- `mime.dataurl=(true|false)`, which determines whether to decode the returned EVM data and set the MIME type according to data URL standard. If the data cannot be parsed as data URL, an error will be returned.

Also I just remember we discussed the mix ?returns=&mime.xx=
If ERC-4804 returns is present, mime.xx will be always ignored : Sound good?
I think we should add this.

Hi! I am going to add more changes for the auto mode, please don't merge this pull request yet! Thanks.

I am closing this pull request because we are in the process of separating EIPs and ERCs into distinct repositories. Unfortunately, as far as we are aware, GitHub does not provide any tools to ease this migration, so every pull request will need to be re-opened manually.

As this is a PR to create / modify an ERC, I will kindly ask you to redirect this to the new repository at ethereum/ERCs. We have prepared a guide to help with the process.

If there is relevant history here, please link to this PR from the new pull request.

On behalf of the EIP Editors, I apologize for this inconvenience.
