Acuity Scheduling vs Cal.com for AI agents
As of 11 Oct 2026, both reach L1 · Needs a person, and our agent got as far with each: with Acuity Scheduling it was stopped at sign up (blocked), with Cal.com it was stopped at sign up (needs a human).
- Find: Some docs for agents: llms.txt and an OpenAPI.
- Access: Signs up sometimes.
- Use: Work not reached.
- Pay: Payment not reached.
- Leave: Leaving not reached.
Stopped at sign up: blocked. Next: let an agent sign up on its own
Needs a person: Acuity Scheduling publishes agent-friendly docs, llms.txt and an OpenAPI spec, but a person must sign up, verify and make the key by hand. Our agent stopped first at signup: the Squarespace account form left Continue disabled with no error, blocked by an invisible reCAPTCHA Enterprise check, and no API route exists to sign up instead. It never reached verification, a key page or a call: robots.txt disallows the entire documented API base, closing that door too. No capability was driven. Pricing shows a no-card trial, but picking or leaving a plan happens in the web app after a person signs up.
Driven 11 Oct 2026 · The drive and its evidence- Find: Docs for agents: llms.txt, an OpenAPI and an MCP server.

Stopped at sign up: needs a human. Next: let an agent sign up on its own
Needs a person to start: L1 · Needs a person. Our agent read the headless docs fine, including a large OpenAPI and an MCP server card, but stopped at signup: the web form shows a Cloudflare Turnstile that stayed visible and never cleared for our agent's browser, so Get started stayed disabled. MCP client registration worked on its own, but authorization then redirects to a sign-in and consent page, and API keys are made in web settings, so no credentials followed either way. With no account, our agent never made a booking call and never reached checkout. There's also no API path to delete an account or the MCP client it registered.

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.
