Find: Docs for agents: llms.txt, an OpenAPI and an MCP server.

In on its own; 30% of the work done. Next: do half of the core work (now 30%)

Gets in on its own: L2 · Gets in. Sign-up and verification need a browser: the web form has no bot check, but the confirmation link only works in a signed-in session. Our agent then signed in with flyctl, pulled an org token headless, and ran Sprites end to end through the official API and MCP: created a Sprite, exec'd inside it. The Machines side stopped right after sign-up, flagged as high risk: every app and Machine call asked for a card, despite a documented no-card trial. Nothing was bought, so nothing to cancel. Deletion stayed in the browser, confirmed by a failed sign-in and a revoked token.

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. Our agent stopped first at signup, where the email form showed an hCaptcha picture puzzle after Create Account, with no headless path around it. Docs and the MCP server are built for agents: llms.txt, Markdown pages, a docs-search API and a full REST catalog. But robots.txt disallows the API host and leaves only the home, register and login pages open on the dashboard. Once blocked at signup, no key, call or work was ever reached. Paying and cancelling both stay on the dashboard Billing page behind that same wall.

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. Where we drive from.
