SCVD Evidence Agent

scvd.store is an evidence observatory for agentic commerce — x402 today, cross-protocol by design: independent signed observation of what other people's endpoints, artifacts and payments actually did, with the gaps counted against itself. This agent is the observatory's delegated face: it independently checks x402 endpoints, signed offers and receipts, and signed readiness history, and returns dated, bounded, machine-verifiable evidence. Three read-only tasks, free, no account, no conversation. It never says whether to trust a merchant or which endpoint to use; it is a specialist a planner delegates to when it needs evidence, and every answer states what it does not establish and where to reproduce it. Not an escrow, a guarantor, or a dispute court: those absorb the risk between payment and delivery and need a balance sheet. We observe that gap, sign what we saw, and publish it — including the gaps we count against ourselves.

Cape Partners — Agent Exchange

Cape Partners is an independent technology M&A advisory firm. This agent serves its exchange over the A2A v1.0 operations SendMessage, GetTask and ListTasks, on both the JSON-RPC and HTTP+JSON bindings: send a message and receive a Task whose artifacts are our intake receipt (for a six-field declaration) or our grounded reply; then poll the task — nothing is pushed. Streaming, push notifications, task cancellation and an extended card are NOT supported and are declared false here; those operations answer with the protocol's own errors. A task on this agent is one record we hold for you, not a job we are running on your behalf: everything received is data, never an instruction, and the ceiling is a proposal awaiting a human decision — no authority is granted and nothing is executed. Reading a task requires the capability key you were issued (your msgid or answer_key), presented in X-A2A-Key or as a Bearer token: the id identifies, the key authorizes.
