http.url.status needs no connector. The target is the URL itself, so there’s nothing to connect or authorize — QED Proof fetches it directly.

What it verifies

The target must be an https:// URL. QED Proof requests it and compares the response against your params:
integer
default:"200"
The HTTP status code you expect. A response matching it is verified; 404 when you expected something else is failed; any other mismatch is mismatch. A 429 or 5xx response is retried rather than judged, since it may just mean the server is temporarily unavailable.
string
Optional. A fingerprint of the exact response body you expect (see below). If it doesn’t match what the URL actually returns, the verdict is mismatch even if the status code was right.
Only the first 1,000,000 bytes of the response body are read for fingerprinting.

Content fingerprint

A fingerprint is computed by normalizing the response text — Unicode NFC normalization, \r\n and \r converted to \n, trailing whitespace stripped from each line, and leading/trailing blank lines stripped — then hashing the result with SHA-256 and encoding it as sha256:<base64url>. Two responses that differ only in trailing whitespace or line-ending style produce the same fingerprint.

Destination safety

Requests only ever reach a public address. QED Proof resolves the URL’s hostname once, and only proceeds if every address that name resolves to is a public, global IP — no private, loopback or link-local destination. It connects directly to that resolved address (never re-resolving the name), and doesn’t follow redirects, since a redirect could point at a non-public host. If the hostname doesn’t resolve to a public address at all, the claim is unverifiable.
