Box vs Dropbox for AI agents

As of 12 Oct 2026, both reach L1 · Needs a person, and with each our agent was stopped at sign up (needs a human).

BoxL1Needs a person

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

L1 · Needs a person describes Box today. Our agent stopped at signup: both the personal and developer forms put an hCaptcha checkbox in front of account creation, and there is no API or CLI path around it. Everything before that door works well: Markdown docs with llms.txt, a public OpenAPI reference, a CLI and an official OAuth MCP server. Past that wall, work, keys and paying all wait in the Developer Console and web checkout, so a person has to open the account before any of it runs.

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

A person has to sign up: L1 · Needs a person. Sign-up stops first: the web form shows an Arkose Labs puzzle after "Agree and sign up," so our agent never reached verification, a key, or a first call. Even without an account, Dropbox's agent surface holds up: public API docs, an llms.txt file, an official MCP server, and headless OAuth client registration through DCR all worked. The Standard trial checkout asks for a card, PayPal, or IBAN; no account was ever created, so cancelling and deleting were never tested.

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.
