Card snapshot

This is a frozen copy of the agent's agent-card.json as we observed it at the timestamp above. We capture a new snapshot every time the card's content hash changes. Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

  "description": "AssetFare is a non-custodial service with 98 technically available routes. Forty-four are price-recommended only at or above their published threshold; 54 have no current price recommendation. Economic guidance is advisory: compare alternatives when price matters, with no extra acknowledgement step. Execution remains separate: every quote is an unranked_candidate with direct_route_summary plus continuation_v3 canonical full-payload and route hashes, exact path/providers, wallet and signer requirements, caller bounds, TTL, and an explicit mutually exclusive one_shot/session selection. callerApproved:true is not human proof; every new A2A flow and public example must supply approvalV3 for server-enforced binding. AssetFare never auto-selects, auto-creates approval, signs, or submits.",
