Backblaze B2L1Needs a person
  • Find: Some docs for agents: llms.txt and an MCP server.
  • Access: Can't sign up.
  • Use: 0% of the work.
  • Pay: Payment not reached.
  • Leave: Nothing to cancel: Can't delete its account.

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

Needs a person to sign up: Pinata sits at L1 · Needs a person. Our agent read the docs headlessly through llms.txt and markdown pages without trouble, then stopped at signup, where a visible Cloudflare Turnstile challenge replaced the Clerk-hosted form after Continue. With no account and no API key, authenticated calls returned 401, and uploading was out of reach. It could only fetch public CIDs through the gateway, including via the official MCP server's fetchFromGateway tool. Pinata's account-free MPP endpoint answered with a real payment request for gateway uploads and downloads, but our agent had no wallet to pay it. No account meant nothing to cancel or delete.

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. 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.
