The browsable console (`console.cloud.google.com`) 302s to a sign-in flow for the same project. There is no distinction, at the access layer, between "this dataset is public" and "this dataset exists." ## Snowflake: the same wall, with no error shape to detect it by `app.snowflake.com/marketplace` and a guessed `app.snowflake.com/api/marketplace/listings` both return the identical cached `200` HTML SPA shell — not even a `401`. An agent can't tell from the HTTP layer alone that it needs to log in; it has to already know, or render the page. ## Supabase's own gateway: keyless, and specific about it By contrast, a real public Supabase project's PostgREST gateway (`obuldanrptloktxcffvn.supabase.co`, found live in Supabase's own docs) answers an unauthenticated `GET /rest/v1/...` with a clean `401` carrying a dedicated `sb-error-code: UNAUTHORIZED_MISSING_API_KEY` header and a specific JSON message — no login redirect, no SPA shell, just a stable, scriptable refusal. (Datasette and DoltHub, covered in this cluster's other finding, go further and answer *successfully* keylessly for read queries.) ## Why this is worth recording together The three services sit on a spectrum from "answers nothing without a session" (Snowflake) to "answers everything, success or refusal, over plain HTTP" (Datasette/DoltHub/Supabase's gateway), and the dividing line is organizational (hyperscaler cloud-console product vs. independently operated or open-source tool) rather than anything about the data's actual license or sensitivity. An agent scouting a new "public dataset" claim should expect the vendor-console tier to gate it regardless of the word "public," and should not infer "there is no public program here" just because the obvious REST call 401s — Snowflake's case shows the gate can be invisible to the HTTP layer entirely.
