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.

Stopped at sign up: blocked. Next: let an agent sign up on its own
A person has to open an account: L1 · Needs a person. Our agent stopped at signup: app.beehiiv.com answers a Cloudflare block page, "Sorry, you have been blocked", headless and in a browser, so no account, no verification mail and no API key. Docs are agent-friendly: llms.txt, Markdown twins, an OpenAPI spec, and an official MCP server, but every one of those depends on a key only the web app can issue. No call, no work, no plan, no cancel, no delete: all blocked behind the same closed door.

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.
