{"protocolVersion":"1.0","name":"AssetFare Route Quotes","description":"AssetFare is a non-custodial service with 100 technically available routes. Forty-four are price-recommended only at or above their published threshold; 56 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.","author":"AssetFare","wellKnownURI":"https://api.assetfare.dev/.well-known/agent-card.json","url":"https://api.assetfare.dev/a2a","version":"1.7.0","provider":{"organization":"AssetFare","url":"https://assetfare.dev/"},"documentationUrl":"https://assetfare.dev/llms-full.txt","iconUrl":null,"supportsAuthenticatedExtendedCard":false,"security":[],"securitySchemes":{},"capabilities":{"streaming":false,"pushNotifications":false,"stateTransitionHistory":false,"extensions":[]},"defaultInputModes":["application/json"],"defaultOutputModes":["application/json"],"skills":[{"id":"quote-cross-chain-route","name":"Quote a cross-chain route","description":"Return one fresh unranked_candidate quote with amount-specific guidance, total token-path cost, direct_route_summary, strict continuation_v3 binding, and route-exact unsigned prepare requirements. price_recommended_for_amount is advisory; compare alternatives when price matters, but no economic acknowledgement field is required.
