Gets in on its own, L3 · Does the work is out of reach: this stays L2 · Gets in. A documented no-account route hands over a working database. Our agent called the claimable identity endpoint from auth.md, got a token, and ran SQL, extensions, autoscaling, scale-to-zero, auth sign-ups and RLS-protected REST CRUD through the Data API without signing up. It stopped at pay: reaching the console for a full account and billing needs a human past a Cloudflare interstitial, and no account-based routes beyond the claimable set were reached. One claimable project's delete call returned success, though its database connection kept working briefly after; the other stayed stuck on a claim lock pending expiry. No account existed, so there was none to delete.

Gets in on its own: L2 · Gets in. Our agent signed up headless, no CAPTCHA, confirmed by email, logged in through the CLI's device flow, and pulled a service token for both the API and a hosted MCP server. It stopped trying to create a database: the API answered that it could not verify a card, and there is no free plan to work around that. Paying needs a card through Stripe Checkout; our agent never attached one, so it never reached core database work. Deleting the account needs the web UI: no API route exists for it.

A check of our network and browser: It judged where our agent connects from and its browser, not a person. An agent that works on its own from a data center doesn't get through unless the owner lets signed agents in. How agents in a person's own browser fare isn't measured yet. Where we drive from.
