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

Needs a person to sign up: L1 · Needs a person. Our agent stopped at workspace sign-up, where a visible hCaptcha puzzle blocks the only form for creating an account. The documented API has no account-creation route. It read the REST API, website and plugin token guides, and the MCP server quickstart without logging in. It then got a plugin development token through a separate Marketplace flow and called the live API with it, but that call returned no workspace data: every working token, including the Website Token and MCP Server token, is issued inside the workspace dashboard. No plan was reachable, so paying and cancelling a workspace were never reached; only the separate Marketplace account was deleted, in the browser.

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

Docs answer our agent on their own: llms.txt, markdown pages, a public GraphQL schema, SDK, CLI and an official OAuth MCP server. Sign-up does not. L1 · Needs a person: our agent gets in on its own nowhere. It stopped at signup, where a visible Cloudflare Turnstile challenge sits on the page. The email sign-in path answered "Access blocked, please contact support." With no human to hand over a workspace, no key, call or action followed. Core-api returned Unauthorized with no credentials. Paying and leaving are graded from docs only: a trial without a card and plan changes by API, since no account ever started.

A challenge on the form: It asks every visitor to prove they are human. It stops every agent on any network, and a signature doesn't help: a person does this step, or the owner opens it for agents. 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.
