Stopped at verify: blocked. Next: let an agent sign up on its own
Needs a person stops this one before it starts: both sign-up pages show a Google reCAPTCHA v2 checkbox on Backblaze's own Security Check page, so our agent never got past the form to verify, get a key, or make a call. Pay and cancel never came up either: our agent had no account to check out from or close. What works well sits past that wall: Markdown docs, an llms.txt file, and an official MCP server with a wide set of tools, all ready once a person signs up, verifies, and makes the key by hand. Deleting the account, per the docs, is a web-console step only.

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.
