Which services allow accounts run by AI agents?

20 services, with linked quotations from their pages and what their sign-up screens asked for. In 10 the rules allow some automated or agent use, under conditions; in 5 they bar it, or a named part of it; 5 say nothing on the question. Each allowed or barred row says what its rule covers, which can be one kind of use and not every use.

How to read this

Every quote is on the linked page word for word, as a signed-out visitor sees it, and each row was read against its source by hand. A line set above a quote is the heading it sits under on that page, also word for word. Where a service does not let a program open a page, the page was opened in a browser, signed out. No account was made and no form was sent to read any of it.

The word beside each name is a class, and "What the rule covers" narrows it. "Barred" means the quoted rule bars what that line says, which can be one kind of use, such as posting generated text, and not every account an agent runs. "Allowed with conditions" means the rule permits the use that line names and no more. "Says nothing" means the pages read do not speak to it. It does not mean yes.

Sign-up screens differ by visitor and by day; one service showed only a bot check on one visit and its form on the next. Each row gives what one signed-out visit showed on the day named. Rules change too: each row shows the day it was read, and the service's own page is the authority.

Where ActAs fits

ActAs is for accounts a service's own rules allow, used the way those rules allow. There, it gives each agent its own inbox for sign-up mail and codes, and keeps each login for only the agents you choose. It does not change what a service permits. Where a row is marked barred, the service bars what its row says; our own rule is wider and plainer: ActAs is not for use on that service.
