Approve indexing without requesting it.

You can use an OP server's badge to request indexing.

Two markup patterns declare that a page consents to being indexed by a specific OP server. Unlike anything else you tell OP with your page, you must use this exact markup. This check only uses a server's default harmonizer, as using a custom one would be defining your own terms of consent for any page you apply it to.

The <meta> form opts in to indexing by any OP server; the <link> form scopes consent to a specific server whose origin matches href. Both tell the OP server it can proceed without a browser-sent Origin header — the page can be indexed from a server-side script, a CLI tool, or any environment that doesn't send origin headers.

To also specify which harmonizer should be used:

<link rel="octo:index" href="https://octothorp.es/">
<link rel="octo:harmonizer" href="https://example.com/my-harmonizer.json">

Or in <head>:

<meta name="octo-policy" content="index">
<meta name="octo-harmonizer" content="https://example.com/my-harmonizer.json">

Domain registration is still required — on-page policy handles consent, not registration.
