- Pay: Payment not reached.

Stopped at sign up: blocked. Next: let an agent sign up on its own
Needs a person before an agent can drive it: L1 · Needs a person. Our agent read llms.txt, Markdown pages, an OpenAPI spec, an AI catalog and an official OAuth MCP server headless, then stopped at signup: the web form's invisible reCAPTCHA rejected it after the email step with "reCAPTCHA verification failed." It never reached a key, a call or any work, through API, MCP or CLI. Paying needs a card entered in the web app's billing settings, and with no account our agent never tested cancelling; deleting an org is a support ticket handled once a month.

Stopped at sign up: needs a human. Next: let an agent sign up on its own
L1 · Needs a person describes PostHog today: docs are built for an agent to read, but no agent can open an account on its own. Our agent stopped at signup: the documented headless path answered 403, "Account creation is not enabled for this partner," and the web form ends in a visible Cloudflare Turnstile. With no account, the key page, the first call and any real work through the API, CLI or MCP server stayed out of reach. Paying, cancelling and deleting were never reached either, since no plan was ever started.

Bot checks, and where a person was needed.

| First wall | Invisible reCAPTCHA rejects agent at sign-up | Turnstile on sign-up; wizard sign-up refused (403) |
| A person helped | No | No |
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.
