Machine-readable prediction-market monitoring, cross-market comparison, and x402-paid market data. No trade execution.
AgentCard object. It is an agent card in spirit rather than in schema — useful for
discovery, but an A2A client cannot assume it will parse.
no-protocolVersionprotocolVersion is nested inside supportedInterfaces[].protocolVersion ("1.0") rather than declared as a top-level A2A 1.0.0 protocolVersion field, so it fails the top-level protocolVersion hard check.Uses the newer supportedInterfaces[] transport model (one JSONRPC interface at /a2a) instead of the A2A 1.0.0 top-level url + preferredTransport fields.securityRequirements is an empty array (payment gating is handled out-of-band by x402, not by A2A security).
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.
