Stopped at sign up: needs a human. Next: let an agent sign up on its own

Needs a person: our agent reached the trial form but could not sign up on its own. A Cloudflare managed challenge, a visible Turnstile check, stopped it at signup, and the vendor's own agent guidance says accounts cannot be created or trials started this way. With no account, our agent never reached verification or the Settings page where a token or MCP URL is issued, so no call and no work through the API, CLI or MCP server. Docs are agent-ready: llms.txt, markdown pages, OpenAPI specs and a docs MCP all worked. Paying needs a human past that same challenge first, and there is no delete-account API.

Got in; payment not reached. Next: do half of the core work (now 38%)

Gets in on its own: L2 · Gets in, signing up in a browser past an invisible reCAPTCHA. Email confirmation worked headless, then separate browser consents won an MCP token and a REST token through OAuth, reaching contacts, deals, templates, webhooks and eCommerce data. Through MCP it created a contact and read it back. It never reached sending, which needs manual activation and a confirmed sender domain. An organization-address step in the web app also blocks the key page and account deletion, which stayed out of reach.

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.
