Human Browser A2A Agent
Agent2Agent protocol surface: an agent card (protocolVersion 0.3.0, JSONRPC, version 5.1.0) served byte-identically from https://agent.humanbrowser.cloud/.well-known/agent-card.json and the website apex, advertising nine skills — browser_task, login_and_scrape, meta_business_workflow, fill_form, scrape_url, relay_reverse_api, hostile_site_solver, email_verified_signup, network_discovery — reached through message/send or message/stream (SSE) at POST https://agent.humanbrowser.cloud/a2a with tasks/get and tasks/cancel, plus twelve provider "actions/*" JSON-RPC methods. Streaming, push notifications (callback_url) and an input-required human-in-the-loop pause with a documented resume contract; every call needs the hb_live_ bearer token (anonymous calls return HTTP 401 / JSON-RPC -32001). Graded conformant against A2A 1.0.0 hard checks.
