As of 12 Oct 2026, Stripe gets an AI agent further: L3 · Does the work against L1 · Needs a person.
- Find: Some docs for agents: An MCP server.
- Access: Can't sign up.
- Use: Work not reached.
- Pay: Payment not reached.
- Leave: Leaving not reached.
Stopped at sign up: needs a human. Next: let an agent sign up on its own
Needs a person: gets in only when a person signs up and makes the key. Our agent stopped at signup, where an "I'm not a robot" checkbox sits between a business form and account creation, with no API or CLI way around it. Past that wall it reached only the public docs, the License API and the official JS SDK; calling the core endpoints without a key returned Unauthenticated, and no key, account or product work could be driven. Paying, cancelling and deleting were never reached: no account existed to test them against.
Driven 12 Oct 2026 · The drive and its evidence- Find: Docs for agents: llms.txt, an OpenAPI and an MCP server.
- Access: Key by API.
- Use: 67% of the work.
- Pay: Reaches the checkout: An agent payment on its API, none made yet.
- Leave: Leaves on its own: Nothing to cancel, what it made goes after 7 days.
In on its own; 67% of the work done. Next: do 80% of the core work (now 67%)
Gets in on its own through the CLI sandbox, no sign-up needed: L3 · Does the work. A working test key, a public key and a claim link arrived from one command, and that key passed the first call and the first action. It drove payments, Checkout, Elements, subscriptions, invoices, coupons, refunds, webhooks and the official MCP server headless. Claiming the sandbox into a full Dashboard account stopped at an hCaptcha puzzle after Create account, so metering, Connect, Terminal and every Dashboard feature stayed out of reach. Stripe charges per use with nothing to buy upfront; going live needs that same blocked sign-up. Cleanup removed the test data, but the sandbox account itself could not be deleted.

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.
