Runs on its own, L4 · Runs on its own: our agent got in with no account, solving a short text puzzle for an API key straight from the docs. It opened a cloud browser session, drove it over CDP, and ran saved tasks, managed logins, profiles, files, webhooks and batches, all on the free tier. Buying more credits needs the dashboard: no payment API or x402 route, so our agent never reached checkout. It deleted sessions, identities, profiles and other resources over the API, though batch records stayed listed after deletion, and found no documented way to remove the project itself or revoke the key.

- Pay: Pays per call for part of it: Paid $0.01 a call (x402), 13 Oct.

In on its own; 20% of the work done. Next: do half of the core work (now 20%)
Gets in on its own, L2 · Gets in: paying per call opens a browser session with no account at all. Our agent read the docs headless, then paid for a session over x402 on Browserbase's own domain, checked its status and shut it down with DELETE, without ever signing up. The key page, agents, functions and higher concurrency all sit behind the dashboard, and sign-up there asks for a phone number, so our agent never reached a key. Pay-per-call needs no plan and nothing to cancel; no account existed to delete.
