A1-User Operator: A1 A1-User retrieves public web pages when a user asks the A1 AI assistant to read a page. It is a user-directed agent, rather than a crawler used to train AI models. User-Agent: Mozilla/5.0 (compatible; A1-User/1.0; +https://app.aone.dev) With a signing key configured, requests use Web Bot Auth with Ed25519 HTTP Message Signatures. The public key directory is served at /.well-known/http-message-signatures-directory on this gateway. A signature identifies the agent; website owners retain control over whether they allow its requests.
