As of 6 Oct 2026, both reach L1 · Needs a person, and with each our agent was stopped at sign up (needs a human).

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

Needs a person to get in: L1 · Needs a person. Sign-up is where our agent stopped: Google reCAPTCHA started invisible, then showed a visible image challenge, so no account, key or OAuth app ever existed. Its developer docs are agent-friendly on their own: an llms.txt, Markdown pages, agent skills and a docs-search MCP server, though that MCP's tool failed in our drive. Without a key, the ping endpoint answered with an invalid-key error, so no work was done. Buying needs that same gated sign-up form; cancelling and deleting were never reached, since no account or plan existed to act on.

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

Needs a person to get in, at L1 · Needs a person. Sign-up stops first: the form sits behind a visible Cloudflare Turnstile check, so our agent couldn't create an account. Verification, the API token page, OAuth login for CLI and MCP, the first call, paying and cancelling all read not reached for that reason. MailerLite ships Markdown docs with llms.txt, an official CLI, SDKs and a hosted MCP server, but none of it gets driven: the product stays locked behind that one form until a person clears the check and makes the key.

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.
