e621.net/iqdb_queries.json doesn't seem to accept multipart form with file with it, always returns an error.
The only thing that works is e621.net/iqdb_queries.json?url= as long it's not e621 address. otherwise it errors out as well.

Well IQDB is like shut down anyway.

So they're not going to keep it? Shame.

IQDB is a private project, it has nothing to do with e6.

I think you're confusing E6's https://e621.net/iqdb_queries with other iqdb that recently shut down.

Does iqdb not use iqdb?

https://e621.net/iqdb_queries seems to be implementation by E6.

https://iqdb.org seems pretty alive to me (so is source code), 3rd party http://iqdb.harry.lu is now shutdown, https://saucenao.com is still up.

I've looked closer at this and discovered, that a POST request to /iqdb_queries.json requires authenticity_token parameter, the same that is in HTML form on https://e621.net/iqdb_queries. It doesn't require authorization, but the token must match your session cookie.

Of course, this is not how API calls should be made and there's something wrong with this endpoint. I guess the POST method has not been adapted to use with the API, and server handles the requests like the ones from HTML form.
I hope this will be fixed, since E6's IQDB (like no other) doesn't allow URLs from domains that are not whitelisted and file upload remains the only way.

It does not (when checking url).
